LG LST-3410A Review and Discussion - Page 240

post #7171 of 7201
You wont get much. I recently bought 2 brand new 3410's off craigslist from a guy in LasVegas who had them from a bankrupt resort construction project.
On ebay I dont think used one's go for more than 100-150, but do the research for completed listings and maybe i am wrong. Good luck.

Wife still uses the 3410a's here, primairly for OTA recording and occasional cablebox SD recording
post #7173 of 7201
I use my LG primarily for QAM recording, as a back up to my two OTA DTVPals DVR's. When it's windy, cloudy or rainy my OTA reception drops to almost zero. Come Oct 3, my cableco is eliminating analog & QAM transmissions. I've never tried hooking up the LG to my cable box. Are you referring to using Video In for SD recording, or the 75ohm RF CH3 output of the cable box ?
post #7174 of 7201
We've ganged 4 cable box SD outputs together, so on our "SD RF Feed" (That used to contain Comcast Analog SD transmissions Now Long Since gone) and I mixed in CH3, CH4, CH 68.
Now that Comcast part is gone, it's our own CH3,4,68 (And 66 in bedroom) custom feeds.... This way 3 of 4 3410a's can record 3 boxes, and bedroom can record off 4 boxes.

On Demand free playbacks have minimized the 3410a use somewhat... but they are still being used....

CH3 RF goes into CH3 isolator & Mixer... This output goes into CH 4 isolator and mixer (fed by CH4 box). HD box's SD output is active, and after a pass through a video Proc, it feeds a CH68 Modulator.
All this feeds distribution to 3410a's cable input.... and bedroom where another SD Box followed by a CH3

Kludge, yes, but until the late 1980's Sony Trintiton dies, I see no reason to purchase a new TV.

In the last few days my unit has started acting up. On both recordings and just watching tv the image has sparkles and horizontal streaks of red, and blackouts. Audio is still present. Do I have a failing video board? I'm considering selling the unit as for most shows I can just watch them on demand.

You didn't mention how it's connected. OTA, cable or both ? Inadequate signal reception can cause such problems,
as can a failing hard drive, the video board or the power supply. I would start with checking all your connections and
reception, from there, format the hard drive from the Menu, and lastly trying installing another drive. If it is the video board,
you'd need to have it repaired or replaced.

What channel or channels is the LG tuned to ?
I can think of many reasons to buy a new TV. Last time I bought a Sony Trinitron was in 1981. Things have progressed somewhat since then....

It's connected via cable and all connections are fine. DTV Signal is within normal range. The hard drive has developed bad sectors. Some recordings would just stop in the middle and I got a message about bad sectors. The blackouts, red streaks and sparkles happen whether watching a recording or just using the tuner.
post #7179 of 7201
Once the hard drive has bad sectors, the LG will not function correctly. I've been through this several times with my own 3410A. I replaced the original Seagate 120GB IDE drive with a Western Digital 250GB SATA, using an IDE to SATA adapter. It worked for about two years, then the WD drive developed bad sectors, and had to be replaced. I've never experienced the video problems you described. I would guess the only way to know if the video board or motherboard itself is at fault, is to repair or replace the hard drive. After that, if the video problems persist, then your only option is to replace the motherboard, or sell it as a defective unit.

That sounds like a heat/bad tuner problem. I had something similar on an (old) satellite/OTA box, and eventually it went kaput.
post #7181 of 7201
My old faithful 3410A is starting to flake out. Where can I get the instructions for replacing the caps?
post #7182 of 7201

Jan J is the expert on this. Assuming you already know how to replace components on a PC board, this post of his should help:

post #7183 of 7201
Thanks. I can probably replace caps OK on my own but if necessary my local PC repair guy should be OK.

I installed a 250gb Quickview drive that I found (new) on eBay a couple years ago. Works fine.

I'd be willing to try some other PVR, but the 3410A suits me fine since I only watch OTA.
post #7184 of 7201
Would replacing some caps fix my video board problem? Although, it may be an exercise in futility; I checked my channels yesterday and every one of them comes up as scrambled according to my 3410. Thanks Comcast! mad.gif

That prompted me to look back at your original problem. Here are your symptoms:

A good way to troubleshoot a problem is to try different things to see what works and what doesn't. You've already started that by noting that you have the video problems whether you're watching live or from disk. Watching live doesn't involve the hard disk as it does on some DVRs, so the disk isn't causing the video glitches even though you know it has other problems. Also, the fact that audio is unimpaired even when you have video blackouts suggests that momentary loss of the incoming signal isn't the problem either.

The 3410A has 4 types of video output (5 if you count S-Video): DVI, Component, Composite and RGB/HV. The latter can go directly to the VGA input that most computer monitors and some TVs have, provided the monitor can handle the scan rate. DVI can be converted to HDMI with an inexpensive adapter and that's the preferred way to go to a TV with HDMI inputs. Most TVs, even old analog ones, have a composite input. Try as many of those outputs as your display will support. You might have to set up a computer monitor near the DVR to try the RGB/HV output. See if you have the video problems on some or all of the other outputs. If the problem is just with the output you normally use, there's a good chance that it's an intermittent connection in the cable between the DVR and the TV or the connectors at either end. I've had trouble particularly with HDMI connectors. Wiggle them a bit and they work for a while. If you're using HDMI into the TV and the TV has more than 1 HDMI input, try a different one. Try a different cable if you have one.

If none of that helps, you can try a diagnostic technique I call slug tuning. Remove the top of the DVR and use an insulated object such as a plastic pen to tap everywhere on the motherboard to see if you can cause the problem and maybe narrow it down to a component or a small area.

You can also thank the FCC for believing the bogus arguments of the cable companies that encrypting everything would reduce truck rolls and save the environment. Comcast is well along in the rollout of total encryption and they may well have done it in your area. If so, you should have gotten a notice with options. But they may just have moved the channels around. Try a rescan. If you have another clear QAM tuner (most digital TVs have one) try hooking it directly to the cable and see if you can get anything. Or use any TV to scan for analog channels. They're supposed to remove them before they encrypt the digital broadcast channels.

I've been away for a while....

All 4 of my 3410a's have had the cap upgrade (Posted somewhere way back in thread)...
Each has had the 'reset' cap replaced as well ......

and on each I've CUT OUT the TVG coupling cap... to defeat TVG...

All 4 are working fine.... and do timed recordings with start/stop & Channel settings... as if it was a VHS machine... Works fine.

Regarding hard drives........

Two of the 4 units have original 120Gb drives in them.....

One has a replacement IDE 250Gb computer hard drive and I've been lucky.. no media errors encountered.

One has a 330Gb 'Quickview' drive and I did have it die under warranty, which was replaced by Maxtor, and the replacement (Now Far out of warranty) is working fine....


Hints on how to co-exist with a drive with media errors:

Actually if you have a recording that will cause it to stop playing because of media errors.... You're halfway to fixing it...
Assuming that the drive only has a few bad spots, and not bad across the board.... IF you encounter a bad recording.... RE-NAME IT: BAD--DO NOT ERASE and don't ever erase it!!! You've just LOCKED OUT the bad spots!!! Hopefully the rest of the drive is good, or, if you encounter it again, re-name it BAD, ALSO, and don't erase it!!!

I've got one 30 min recording marked this way one one of the systems, and we renamed it bad-do not erase over a year ago... Haven't had any issues, as subsequent recordings are occurring outside of this bad area....

My $.03

Mine is in it's original condition except for the hard drive. Works fine using cable QAM and OTA. When powerered up, the message on the screen reads "the search for data has failed"...... and that's it. No problems except I cannot edit the 'Channel Listing" screen. No need to unplug it every three days like years ago, it has been stable for most of 2013.

For anyone interested, there's another thread on AVS which describes forthcoming high-definition OTA recorders from Philips/Magnavox. Two distinct models, one with a 500gb laptop hard drive, the other with a 1tb laptop hard drive. Single tuner, manual recording similiar to the LG.
It's been unclear as to when these models will be released. So, those of us who still own LG LST machines, or Sony DHG, DTVPal, etc. will have an alternative coming to market.
post #7189 of 7201
I've never seen that error message, what firmware vesion are you using? Or, maybe it just doesn't like the hard drive?
post #7190 of 7201
It's software version 1.17, 7/23/2004. I think it just means no TV Guide data has been found. When Guide data was available, I never saw that message. The hard drive works fine, don't believe the drive has anything to do with that message.
post #7191 of 7201
I've got V1.17 in all 4 here, and TVG caps pulled.... Never saw that error message...

Anyone else?
post #7192 of 7201
just picked up a brand new 3410 last week for $100.

Didn't you remove the caps prior to the demise of TV Guide ? If so, one would have to assume the LG no longer searches for data, in which case the error message would not be shown. This leads me to believe that it's not necessary to remove those caps with the absence of TV Guide data, unless the machine is malfunctioning due to other causes
post #7194 of 7201
$100= good price. definitely worth it
post #7195 of 7201
The TVG Cap I pull removes the signal to the TVG Board.... It doesn't stop TVG Board from Searching...

Removal of the TVG cap was determined during the days that CBS transmitted an Advanced TVG Signal on their SD feeds to Cable Companies.

That signal would over-write the TVG Ram, Locking up TVG board, which also locked up the 3410a, which could only be resolved by a power reset, which, in combination
with the Ram Over-Write erased the TVG Ram.... forcing the 3 day reload and lockup issue.

But with no signal at all going there, it can't possibly misread the signal (SD only)...

Removal of cap may not be an absolute necessity, especially since CBS gave that part of TVG the heave-ho... but it certainly is an Absolute... smile.gif!
post #7196 of 7201
Well obviously, whatever works for you.... works for you. My LG is still functioning very well, with the cap intact. I see no need to change anything. At most the current hard drive will acquire bad sectors, or have to be replaced. I recently purchased a Channel Master CM7400 at an extremely cheap price on EBay to add to my collection of HDTV recorders. So if and when the LG bites the dust, I will still have five other HDTV recorders to use.
post #7197 of 7201
Cap intact here as well...and still on original hard-drive! Only gets light use (about once a week), but still has a great picture!
post #7198 of 7201
I think the cap issue is a moot point now after the removal of TV Guide. Most cable companies are eliminating analog and QAM transmissions. I had no luck with the original Seagate hard drive, it kept on developing bad sectors, almost making my machine unusable. It was only after I changed the drive (and the internal ribbon cable) that my LG began working consistently for the last few years. I use mine several times per week, and it records very nicely. Too bad LG never issued a follow-up model, with an HDMI connection and things like twin tuners. That would have been great.
post #7199 of 7201
Anyone know where to get a new unit? $200. on ebay does not appeal to me.
post #7200 of 7201
Not much else besides Ebay and Craigslist. Sometimes members here have one for sale on occassion, but it's rare. I agree $200 is a bit much. If the seller doesn't get rid of it, maybe he'll lower the price.
