Jim1348,


My original STB3500 suddenly stopped working as you described. I took it apart and noticed two capacitors that had gone bad. I picked up some at the local electronics store for less than 5 bucks, soldered them in and my unit has been working like new again for months now. Look for leaking or mushroomed ends on the caps. I had one leaking and one mushroomed. It was pretty obvious what had failed.

Don't know if this is possible with the 3500, but @fathereagle modified an eMatic to run off a 5V wall-wart (often sold as USB chargers):

RE: I have a 3500STBII and am anxious to upgrade my firmware (S/N 1511xxx, SW Version: 201522V5.00; HW Version 7802123783650) to fix the "Add Event" bug .. I took your advice, navigated to http://www.iviewus.com/firmware3500STBII/ and downloaded & installed IVIEW-3500STBII (EPG Fixed) - 1511 - 6 MB - 10/31/2016. I am happy to report that the "Add Event" bug has been fixed JH .. Update on above (EPG Fixed) f/w update .. Now the "Add Event" feature works correctly, BUT the unit does not always record the scheduled/booked event. Seems to be a hit-or-miss recording bug. Sometimes you get a recording error message. Additionally, pressing the red RECORD button does not always work.

Uh-oh; can you provide more details? What does the recording error message say?

JH .. The error messages state: "Enter Recording, Waiting" and "Unknown Error, Leaving". I use a fast SanDisk USB thumb drive that has been performing well for over a year. If I turn the unit OFF, then reboot, the error messages go away and the unit records / plays perfectly. Also, if I do not reboot, the unit will not play any previously recorded programs on the USB drive. Have you experienced these error messages, issues? Interestingly, if I select a program to be VIEWED, not recorded, the unit switches to the correct channel just fine with no error messages. Do you think the 1604 firmware might help ?

The 1604 firmware is worth a try. I haven't run into this issue myself so I don't know for sure, but it might help and I can't see any reason not to try it. You can always flash the 1511 firmware back on your box if 1604 doesn't help.

When I tried the 1604 firmware on mine, I noticed several bugs but they were all pretty minor except for the CC on playback bug. But if the 1604 firmware records more reliably, that's probably more important.

If changing the firmware doesn't help, you could also try another HDD, even though the one you're using has been working until recently. Perhaps the new firmware versions don't get along with it for some obscure reason.

It sounds like your box's USB port just quits working somehow after it's been on for a while. It's hard to tell if this is a new firmware bug or a hardware issue such as overheating. Maybe it's been a problem for a while but you're just now noticing it because you're using it more now that the "Add Event" bug is fixed.

Good to hear the EPG entry works, as well as the "bare channel entry" fix. That is a real pain, currently.
I discovered something interesting about entering "bare" channels with the new firmware: If you enter a bare channel number, it first looks for a matching channel number, and if it exists it tunes to the lowest subchannel for that channel. So, if I enter 23, it tunes to 23-2 (because I've flagged 23-1 as a "skipped" channel). So far, that's pretty normal.

But here's the interesting part. If there isn't a matching channel number, it looks for a matching subchannel of the current channel and tries to tune that instead! So, let's say I'm on 30-1. If I punch in "4" it'll go to channel 4-1, because that exists; but if I punch in "3" it'll go to 30-3, because there's no 3-anything in my area, but there is a 30-3!

So with the new version, you can change to a different subchannel by entering just the subchannel number if there's no matching channel number in your area. Note that's always true for "1;" there's no channel 1 anywhere so entering 1 will always take you to the -1 subchannel if your current channel has one. (I suppose that's also true for "37" but I've never seen a channel with 37 subchannels!)

I think that's what they were trying to accomplish with the firmware your 3200 shipped with; they just didn't get it right until this new version.

Wow, cool find. At first glance, entering a non-existent channel number and it going to a sub-channel sounds great, as it saves you the step of entering the "-" as is the convention on must tv's. But on second thought, it should default to the current channel if a non-existent channel number is entered (so as to not add to the confusion). I give iView a "B+" for effort, but a "C-" on execution of this issue.

BTW, in many TV markets around the country, there really is an OTA channel 1. The reason being is that all the channel numbers we are talking about here are "virtual channel numbers" as per the ATSC spec. True, there is NO "physical channel number 1" as per FCC specs, but often the (virtual) Channel 1 is used as a combo channel guide and advertising channel for the local TV viewers.

I'm still debating whether to upgrade the FW, given the minor quirks. They got most of it right, but I'm still on the fence. LOL

I never heard of an OTA channel 1 or 37, but many cable systems have them. So I checked with RabbitEars.Info, but I couldn't find an OTA virtual channel 1 or 37 there either. Still, there's no reason you couldn't have, say, a channel 1.1 if you wanted. It could be just a low-bandwidth subchannel of an ordinary station in the area (like many weather channels), and it would make sense to broadcast one of the old "slow-scroll" channel guides there.

It's just that legacy OTA stations set their virtual channel to their old analog channel, and new ones set it to their physical channel number if it's available, and if unavailable they make a "closed loop" with the station with their physical channel number. (For instance, in DFW, after the DTV transition we ended up with legacy channels 21 on RF 29 and 29 on RF 30, so when a new station went on the air on RF 21, it became channel 30, closing the loop.) Since no one was on channel 1 before, no one ever ends up using that channel number now.

(Trivia: some cable systems have a physical channel 1! It follows channel 4, and they move channels 5 & 6 up by 2 MHz to make room. This cuts a couple MHz off of the 20 MHz-wide FM band, but these cable systems usually take that over for physical channels 95-97 anyway. I don't know if the iView has a way to tune physical channels 1, 5, and 6 on these systems.)


Most of the quirks I found in the new 1603 firmware aren't present in the 1511 firmware iView posted on their 3500 firmware page, so that's the version I finally went with. My System / Information page now incorrectly reads Model: iView 3500STBII, and the new 12-hour time format isn't quite right, but I can live with that.

BTW, I think if you enter a non-existent channel number, it's probably a mistake; not an attempt to change subchannels. So while the iView's trick is neat, it probably isn't what you were trying to do. So if I enter a "3," the old behavior of just reporting "Invalid Channel" probably makes more sense than going to channel whatever-3.

OLD SanDisk Cruzer Blade .. NEW SanDisk Cruzer Glide. I know these models aren't the fastest, but they record 1080 just fine with no playback glitches. Have also successfully utilized SanDisk Ultra 3.0 64GB.

Question

JH: Upgraded my firmware (S/N 1511xxx, SW Version: 201522V5.00; HW Version 7802123783650) to fix the "Add Event" bug ..but unit misses timed recordings. The error messages state: "Enter Recording, Waiting" and "Unknown Error, Leaving". Tried a different San Disk thumb drive and thought recording problems solved. Will see if this is a "permanent" solution, if not, I will try f/w1604 and report back.

JH .. Unfortunately, the Recording Error messages returned using SW Version 20160815V5.0 Just installed f/w 1604 with hopes it will remedy missed recordings. SW Version now reports: 20160923V5.0. Hopefully I can report better news in the future. Thanks again.

P.S. I noticed the iView download page now has a WinRAR "Trial" version (misspelled "Trail" on d/L page http://www.iviewus.com/firmware3500STBII/ If f/w 1604 doesn't resolve recording issue, might this be another alternative ?

I think that's just a trial copy of WinRAR (Windows software to open .RAR files), not firmware.

If you still have trouble, you might give this thumb drive a try:

iView newbie coming from TiVo and DirecTv.

I have a STB3500II, just purchased from Amazon.

Model: iVIEW-3500STBII
SW Version: 20160815V5.0
HW Version: 78021237836650
Serial: 1609-3500STBII-DZ3676

Remote works very well.
Tuner is very good (using Chicago OTA only).
Channel surfing is quick.
Boot is around 15 seconds.

Seems real good so far.

Will I gain anything upgrading the firmware on this box?

Thanks!

The info you posted seems to match the "1511-EPGFix" firmware version posted on iView's web site. My experience with it was very good; in fact, I left that version on my iView 3200!

But @LH92037 had some problems with failed recordings to SanDisk thumb drives with that version. LH92037 is now trying the "1604" firmware version which is similar, although I found a few minor bugs in it. It hasn't been long enough yet to know if the 1604 version fixed the recording failures, but I'm sure we'll get a report soon.

My advice is to leave your box's firmware alone for now, but keep following this thread in case you too experience occasional recording failures.

JH .. The 1604 f/w update solved both my "Add Event" bug and failed recording problems (without having to purchase a new thumb drive). As you noted, 1604 has a few minor bugs, but no deal killers. BTW, I noticed iView has added another f/w download .. 1309 dated 11/29/2016. Have you experimented with 1309 yet ? http://www.iviewus.com/firmware3500STBII/

Glad to hear that 1604 fixed your recording failures!

Both 1511-EPGFix and 1604 are very new and we haven't had much experience with either. The big knock I had against 1604 was that if you pressed CC while playing a recording, even accidentally, the box would lock up. The other bugs I found were all pretty minor. But if 1511-EPGFix won't record reliably, that's more serious than the CC thing. (It would be nice if iView had a firmware version without either problem.)

I did download 1309 and extract it from the .rar. It turned out to be simply V1 for the 3500s with the channel 3/4 switch. I compared both usb_upgrade_all_flash.bin files and they were identical. I'm not even sure why 1309 is there, since the very same firmware (minus the .rar envelope) is available further down the page (along with V2a and V3 for the same boxes).

Newbie here. Purchased a 65 Vizio "TV" on Thanksgiving evening and didn't notice that it didn't come with a TV tuner....

That being said, I picked up this guy off eBay in order for it to work with my Brighthouse basic TV service via coaxial cable.

I ran the channel search and it pulled quite a few channel but none of channels are labeled and the epg is virtually useless since each channel has a strange set of numbers to identify them(NBC HD is 81-2608). My zip is 33809.

Is there any way to get a more useful guide?

From the new iView tuner itself? No.

You may get more channel lineup info by entering your zip code here:

Not really with the iView. Cable companies have their own proprietary channel mapping and program guides that iView's firmware doesn't understand. So your experience is pretty common: it works, but you have to do a lot of work to ferret out which channels are which and rename them - and hope that Brighthouse doesn't move their channels around and make you start all over!

If you're just looking for a tuner and don't need the iView's recording ability, you might check out this box: http://www.samsung.com/us/support/ow...yer-gx-sm530cf. You can even add a CableCARD from your cable company to tune encrypted channels, but it will tune unencrypted channels without one.

I need some help with my iView-3500stb, it's been awhile since I've been on this forum. The 3500 has been working well since I got it in 2013, but recently the cable company changed the channel mapping and I had to rescan. I've been using firmware version 053013_V6_QAM_PHYSICAL. both v6 and v7 had about the same results for me. But it had been working fine well until the cable company started screwing with the QAM layout.

But here's where I am stumped/confused/baffled. I cannot pick up the frequency block of 309mhz. There are channels there as verified by a 3500STBII, but that display output for composite video is NOT as bright as the original 3500STB. I would like to keep my original 3500stb instead.

What I don't get is how can just one frequency be missing? I've tried all sorts of firmware, including the newest from iview, and it will not find that frequency. I was thinking if a tuner was bad why would only one single frequency give out?

I would appreciate any help that can be offered. I tried everything I know.

What firmware was the 3500STBII that worked using? I believe the 3500STB can run V9 or V13 (latest versions for the original 3500STBIIs) if you have the new 3500STBII remote, so if the 3500STBII was using one of those versions, try it on your 3500STB. (The 3500STB definitely won't run V1-V5 for the newer 3500STBIIs though.)

Just to be sure, the 309 MHz block is physical cable channel 38, right? The only thing I can think of that might be different is if it's QAM256 and the others are QAM64 (or vice versa), and perhaps the original 3500STB tuner won't tune QAM256, but I don't know why the cable company would use a different modulation on only one channel. So I'm probably wrong about that; it's just all I can come up with.

Unencrypted QAM is going away slowly but surly. Many cable markets already have completely done away with it. Maybe they figure removing it one channel at a time will make it less of a blow?

Thanks for the reply! The serial number started out with 1609 for the 3500STBII, so I used the latest software from iview. File name is IVIEW-3500STBII (1604), dated 09-08-16.

I do have V9 and V13 firmware versions, not realizing those were for the first generation STBII's. I did try those and no improvement. What was odd when I used those versions the signal strength of the cable channels were around 30%, and the picture was pixelating. I switched back to V6/V7 (same performance) and I had 85-92% signal strength.

I also agree that I doubt the cable company would change the modulation from one to another only for two channels! I have the number of the manager over the entire area where my cable system is, I did talk to him before and that's how I found out that the channels missing were on the 309mhz block and yes it's physical cable channel 38 for that frequency. I am also missing 303mhz right below it.

Now about the firmware you were saying from the earlier STBII. I did find an earlier version with serial number starting with 1309, my 3500STB is a 1305 so I'm thinking that one is close enough as you were saying. I could try that. Just didn't want to brick my tuner.

What I did do to make everything stable (minus the two channels) was used the latest firmware for the 3500STB. That gave me the actual network channel names in the channel list, but it wasn't the strongest signal (pixelating), so I then flashed to V6 but did not do a factory reset. And so far I now have a channel guide for some of the re-broadcasted OTA channels. that was nice! I am also going to contact iview and see what they have to say..

Thanks for the advice! At least now I know it has to be a firmware problem not an actual hardware issue.

I looked at the 1309 firmware version on the iView website. When extracted, it appeared to be identical to V1, which was for the 3500STBII boxes with the channel 3/4 switch, so I don't think it'll work with the 3500STB. (The demod chip is different.)

I don't know why iView posted it on their website that way, since the boxes that used V1 didn't start coming out until mid-2014. Besides, V1 is posted further down on the same page! I wonder if they meant to post V13 and just grabbed the wrong file?

Your 3500STBII that worked is one of the new ones. That box uses a 7802 SoC and a 1237 demod chip, while the 3500STB uses a 7816 SoC and a Samsung demod (not sure of the Samsung chip number), and of course those changes require different firmware too.

Interesting that the signal strength reading was so different with V9 and V13. There may be some difference between the tuner in the 3500STB and the one in the first 3500STBIIs.

So that's four differences between the box that works and the one that doesn't: the SoC, the demod chip, the firmware, and it looks like the tuner chip is probably different too. I don't think you can yet say which difference is causing the problems with channels 37 and 38.

But I think you've tried all the firmware versions that have a chance. Won't hurt to ask but I doubt iView does any firmware development on older boxes once they start selling a new box; heck - they can barely handle firmware for the current version of their box!

Thanks for all that info! I did receive channels 38 (6 channels on QAM within that block) before the cable company began moving stuff around. They have never left anything alone just keep messing with stuff, including the cable internet.

You're right iview won't be spending any more time on firmware for an older tuner version. At least I know it has to be something to do with the firmware and not an actual tuner issue. Since it's a software tuner and to lose only 2 sets of frequencies doesn't add up.

So my options are to just keep what I have and let the two channels on the 309mhz (channel 38) go away, or get the 3500STBII and use that.

The one issue I did have with the 3500STBII I received was that the display was very dim. Almost as if the brightness control was turned all the way down. I flashed the latest firmware, that brightened it up. But it was never as bright/vibrant as my original 3500STB. Guess nothing is perfect. But thanks for spending the time helping me understand what's going on. I kinda thought it might be the firmware causing this. And I've tried all I can.

I would like to know, if you or anyone knows.. is there a better stand alone QAM tuner out there than the 3500STBII? I've heard the homeworx isn't so good lately.

UPDATE:
I was looking around on the forum and saw that Channel Master has come out with the7003 ATSC/QAM tuner. I ordered it from Amazon via Solid Signal. I will see if that solves all the problems and yeah it's the 7816 chip but maybe the display will be brighter than that of the 3500STBII. I'll update this soon, should have it this week.

Actually the CM-7003, as well as the new iView 3500STBIIs, use 7802 chips now. All the importers (iView, HW, eMatic, etc.) seem to have switched from the 7816 to the 7802 in the last year or two. I suspect the 7816 chip isn't made anymore.

You can usually see which chip a box has by going to "System/Information" and looking at the HW Version. There aren't many differences between the two chips, but there are a few you need to be aware of:

  • The one good thing I know of is that firmware for the 7802 chip generally supports closed captions on playback. (Unfortunately, some of the new iView firmware versions have bugs in this feature.) The 7816 firmware never did that, AFAIK.
  • The recording format is slightly different, meaning you can't easily take recordings made on a box with one chip and play them on a box with the other chip. You can often work around this by using a PC to rename the files, changing the extensions from .mts to .m2ts, then playing the renamed recordings in the "Movie" section of the USB menu instead of the "PVR" section.
  • Obviously, cross-flashing firmware between boxes with different chips is a big no-no! It will most likely brick the box.
