Artec T3A Pro NTIA CECB - Page 7

I have 2 new T3AP-LL's. Both are not getting 12-2. Both were.
I also have a Zinwell which does get it so it is broadcasting.

The LL's are showing no signal and it does not beep yet the meter is showing a very strong signal.

It does ID the channel and it does show the guide, with good signal but says no signal.

They have no picture.

I tried factory default. I scanned with no antenna and again with antenna.

It picks up the channel and adds it to the list but no picture.

I can't believe both boxes are broken unless it is a defect.

As I said, they are both new. One used for about a week and the other for 30 mins to test and make sure it worked ok.

I sure could use some help on this one!

OK, I'm in. Just ordered one of the 'Pro-less' LLs for absolutely free from www.freetvsignal.com . The extra 10 bucks for the Pro was tempting since it has CH/VOL buttons and a set of A/V cables (how cheap Q though?) but not knowing the tuner type swayed my choice.

I jumped on it after I discovered it ran off 12V DC. My neighbor just gave me a portable 5" analog LCD that comes with a cig lighter adapter so I was trying to piece together a camping setup for my van (stationary). I did a little research based on the mfger's website http://www.artectv.com/ehtm/products/t3ap.htm :

1) Both the regular and Pro use only 4.5W max, excellent for portable apps.
2) The TVGOS version (T3APR-T) uses 7W max; must be an added chip for that function.
3) They DON"T specify them for automotive use so I would suggest NOT leaving it plugged in while the engine is running (13.6V+tolerance &noise with alternator spinning unless your car has a fancy 12V auxilliary device regulator).

Thanks to everyone, esp Yankee for the review and Ron for the vendor link.

It almost sounds like it's keeping old info in memory even though the signal may be too weak for it to properly pick up. You might try deleting whatever you can find about that channel (main and subs) and starting over. Wish I could help more but I don't have an Artec yet.

Those Zinwells are sneaky if a station changed something on you. I had a station change but my Zinwell still displayed the new station on the old virtual channel.

I bought a Artec T3AP-LL from Meritline last week, and have taken it apart (you just have to take off the two footpads at the front of the box to get to 2 screws, and pop the top off. It has an LG-Tuner inside.

Here's a photo of the circuit board if anyone is interested.

Thank you!

I believe my problem may be the station. We had a severe storm a couple of months ago that took down this stations tower and destroyed the building(tower fell into the studio and a house! Not a pretty site)! They were off air for over a month!

http://www.wirelessestimator.com/wif...r_Collapse.jpg

They are using a sub channel of KODE 12 (12.1). It is KSNF 16 (12.2). They are getting their own channel going...I am getting it...16.1

I just can't figure out why the Zinwell gets 12.2 and both Artecs do not...they did get it just fine. I'm thinki9ng about calling the station and ask them if they are doing something. I just need to know if it is the Box (The zinwell working worries me).

Any help would be appreciated!

And Floydage, you're gonna love the LL's! (if this is not a defect!)

The LL has 3/4 signal but says no signal. You know....I didn't delete it from the Zinwell and try to get it back! Bingo, maybe?

Also see above about tower going down....I bet they are doing something and the Zinwell is still showing it....will report back...

It can't be my beloved Artecs!

Great Pic Bluesloth! All we need now is someone to wire up that 3 pin data port so we can screw'em all up!!!

Hahaha...

Floydage,

I was leaning toward some genius at the station. Now Zinwell has no sound. A rescan brought it back the same way, no sound.

Whew! I was worried for a minute!

And, I almost plugged the Artec power supply into the Zinwell! I don't think that would be a go! 12v into a 5v box...you guys watch out for that!

OK, the station has a picture on the Zinwell and no sound. It had color bars for about 10 secs and then no pic and then pic and no sound!

You can all relax now....it is not the LL's

I just check out freetvsignal and they list the LL as having an LG tuner. Meritline doesn't.

Also they list the specs as "3-4 channel switch x1", which it doesn't have a switch, it is in the menu which I like!

I cant seem to find a code on my ReplayTv 5040 that will change the T3A Pro channels.
Does anyone here have a ReplayTv working with the Pro box?
Thanks

I tried a universal remote...it was a no go all the way.

The remote will power off a zinwell, but that is it.

I am sure the answer is the same for both, but I mean so the replaytv can tune in a channel for automatic recording.

What brand box works best with replayTv?

Thanks, I really miss automatic recording...

Thanks and nice pic! You just voided your warranty but I won't tell. LOL

That's the same tuner listed for the Zenith/Insignia boxes, supposed to receive pretty good from what I've read. LG Decoder IC the same too (med pic Q per Consumer Reports).

Ouch! Those things are horrendous when they come down, good thing most are out in the sticks. Guy wires are real killers when they snap too.

Good point on the DC connectors as I suspect it's a pretty common component. Ironically I was just looking at those for my 'RV' setup. I wish I knew what type it's called, was trying to explain to a friend over the phone (works for an auto electronics dist.).

DC cable:

If you have a thrift store around go there! They have all kinds of power supplies (wall warts) and you can just find a plug that fits and cut the cord off!

I get them all the time for 50 cents!

We have a salvation army thrift store...they have a couple of boxes full...

WATCH THE POLARITY!

Good idea - thanks! Come to think of it I probably have a thrift store of this kind of stuff in my spare bed (storage) rooms; but hard to get myself to cut one up, never know if it belongs to something I'll need someday. 50c sounds better. Can also get a variety of voltage sizes to complete sort of a makeshift variable power supply set.

I chose to get a couple of free boxes (with free S&H).
These are the folks that topped Google, so I tried them.
I ordered these two, and they arrived just fine, and free!

Artec - T3AP Pro 5-Button Wiring Info:

For T3AP-LS (Sanyo tuner) ans T3AP-LL (LG tuner) the following is correct
Pin #1 is FARTHEST from the tuner / closest to LEFT side of equipment

For the T3AP Pro modelthe following is correct
Pin #1 is NEAREST to the tuner / FARTHEST from LEFT side of equipment

Determine which last pin/pad is chassis ground and Pin-7 as confirmation

1 - +3.28-VDC (Measured) for four function buttons (Vol Up/Dn, Ch Up/Dn)
2 - Power on - Switch goes from Pin-2 to Pin-7 chassis ground (Tuner casing...)
3 - Channel Up - Pin-3 To Pin-1
4 - Channel Down - Pin-4 To Pin-1
5 - Volume Down - Pin-5 To Pin-1
6 - Volume Up - Pin-5 To Pin-1
7 - Chassis ground, and ground for two jack support solder pads also

See NTSC's Post #236 for additional details & pics
This is what the T3AP-LL looks like without the surface mount style 7-Pin connector:
Ron350 confirms earlier LS/LL units were populated with the surface mount 7-Pin male jack.

I now see why this hack became a reality...

No registration needed.

Do you think vent holes voids the warranty? LOL

You're hired - nice! Reminds me of when we dissected competitor products at my last job. We had the first product out so I didn't feel too bad about it.

Based on that switch design, maybe it's a good thing I didn't spend the extra money for the Pro (CH/VOL buttons); but then again I have to rely on that flimsy remote. LOL

I see the SOC power consumption equates to 8W. They must be running it at a lower consumption mode (lower supply voltage, duty cycle, etc.) and/or not using all of the functions. I take it the D and T suffixes describe different IC package types.

Thumbs up or thumbs down on the Craig? I can't find a thread on it performing a "Google Search AVS." The brand gives me visions of drug store cheap stuff (but hey, I read here that Zinwells were once sold in Albertsons!).

Should extend the warranty IMO.
Holes on top look OEM - nice drill press work!

I wonder if a small heatsink can be thermal-glued to the top of the SOCs of these boxes? Might get in the way of the WSE (Worst Switch Ever) on these Artecs though.

Despite the distaste for wall-warts, they do remote power supply heat from the box.

It looks like it has a place to mount another switch...to the right of the firmware sticker...

But not enough to be the same board as a pro...

It also looks like straight back from the data port there is possibly a ribbon cable that could be added..maybe these are for the channel/volume switches...

Found a firmware bug.

Hit freeze. Leave it there for one minute. It will start motion video again but leave the "freeze" info up. Hit freeze again and it will freeze but the "freeze" will go away.

Hitting EPG blackes out all channels...with "no signal"....even if you exit.

It comes back in about 1 minute and is ok...

Hey Floydage,

Ole ron350 can put a switch anywhere he wants! Gotta enough holes!

Use the big hole for a fan, and put a small switch somewhere else!

Hahaha

No, really...looks nice...factory should've done that or something like that.

Mines runs pretty cool...Sunkeys run hot!

But you guys are right....heat is the enemy.

Floydage the plastic box and the switch arm just snap together so you can take the switch arm out and have extra room and an extra cooling hole.

Yankee495

See post number 145 for a picture of the older LL board and you can see what they left off.

It is a switch & connector...what for? Anyone push that button?

That missing switch acted like a reset button when pushed?
The box would blip off the back on just like you had pushed the power button twice. As far as I can tell no settings change when that button is pushed.
The Freeze feature only lasts for 1 minute even on the LS box.

Indeed, #145 shows a cable connector and switch in the aforementioned optional spots. Might be a tiny LED in the 3rd open spot just NE of the RCA connector (bluesloth's LL pic). Maybe #145 is a Pro or older version with CH/VOL buttons?

Cool, has a Freeze function.

I doubt the code is thoroughly tested on CECBs. Can be pretty extensive, think of all the permutations.

Darn, you just missed the free fancy $9.99 antenna with every Craig 508 purchase (today).
