Westinghouse LTV-37w2hd was working, now turns on and halts on W logo or Blue screen.

[Shinju]

Hey friends!


I got this 37" Westinghouse for 5.00 out of the recycle pile at the local VV today.

I got it home and plugged it and and it fired right up, I plugged in my HDMI bluray player and watched Avatar from start to finish on it. Was working great, had a great picture, sound ect.

After the movie I decided to go into the menu I hit the menu button and it brought up the menu and then BAM the backlight went off but the audio was still going.

I couldn't turn it off as it seems the buttons were locked out. I unplugged it and it came back on with a solid blue screen, again I couldn't turn it off via the button. After a few more times I finally got it to turn back on and show a picture but no audio and the buttons were not responding and now its just stuck doing the W logo or a blue screen.

I searched here and didn't find much on this unit but could this be a bad mainboard or a corrupt firmware? I couldn't find any firmware updates for this unit.

I can take it apart and get photos of the boards, these are a pain! lots to remove

Sorry not much to go on here, I will try to tear into it tonight.

Was crazy it was working great I was really impressed by it as I had it next to a 40" Sammy and it looked more natural.

Thanks for reading

Yea just from what you have said it does sound like a main board. Since that controlled the turn on and sends the video signal and signal to turn backlight on and off. And beig stuck on the logo would should kinda like the EEPROM issues vizios have.

Lame! If only I had a firmware update to try and push to see if it can be resolved.

I am going to take it apart and see if the eprom is socketed like the newer gen one I took apart today for a friend. That one too has a bad mainboard as the PS is putting out the right voltage. It just sits dead with a Orange LED.


Thanks for the reply, I might just get a new mainboard I only have 5 bucks invested and they seem to be pretty reasonably cheap.

I would just try to get a new main board. Your probably not gonna find a EEPROM for that main board.

So I ended up getting the entire guts to a 37hd for super cheap. The tv fired up and I was able to surf the menu and change inputs ect. I have not put a singnal to it yet.

My quest is the original mainboard was power by ATI CPU the new one is not, is there going to be a difference in picture quality? Does anyone know of a place I can get a firmware update?

I will report back when I get to see a signal work. Also I have a ton of extra parts for one of these minus the mainboard.

If you can get a update it would be from the manufacturer website.

I tried their website no dice, good news is the tv works the bad news is the HDMI port seems to be bad and doesn't work. I tried a Facotry reset with no luck. The funny thing is if I have a composite source and plug in the hdmi cord it switches to that input and says HDMI no signal detected, does this even if I select it manually or turn the tv off then back on.

No audio on any input! Lol well shoot.

Hey friends.

I got another mainboard, this one is an ATI mainboard same as the original one. Again I have no HD, HDMI, no componate and no audio. I do however have standard AV with no audio.

I did the reset all, reset picture and reset audio. I am at a loss on what to do, there was these foil sticky stripes on the shell of the main/ps case that attached to the back if the panel and one smaller strip that attached on the part if the mainboard near the t-con connecter that stuck to the backside of the shell that housed both the ps and mainboard, do those strips need to be there? Are they more then just a noise/interference strips?

I cannot believe that 2/2 mainboards are DOA in the same manner, well almost the non ATI board all inputs worked (no audio) and the hdmi was dead.

Any suggestions on what to try for next?

Another thing to note aswell, the auto signal sense is on and when I turn on a device it switches to that input and and after 2 seconds it says no signal and goes into stand by.

Re: Westinghouse LTV-37w2hd was working, now turns on and halts on W logo or Blue scr

do you get sound on the TV input using an antenna?

[Shinju]

Re: Westinghouse LTV-37w2hd was working, now turns on and halts on W logo or Blue scr

I don't have cable, but I can hook up a game system using rf.

[Shinju]

Re: Westinghouse LTV-37w2hd was working, now turns on and halts on W logo or Blue scr

No audio using RF, I have an HD antenna I can try but I am not getting any audio with RF I don't think the hd antenna will change that but I will try

Thanks for the suggestion!

Sounds like those MB's not compatible.

Re: Westinghouse LTV-37w2hd was working, now turns on and halts on W logo or Blue scr

I don't think it's that, I have the entire guts to another Westinghouse here and althought the mainboard and power supply are different revisions the harnesses all match up, even the t-con and it's cables match up.


I put in the non ATI board back in and I think I am just going to sell it as is and return the other ATI mainboard. The non ATI mainboard at least had all working connections besides HDMI.

Oh and the speakers work, I ohm tested them and hooked them up to an external source.

Re: Westinghouse LTV-37w2hd was working, now turns on and halts on W logo or Blue scr

what about +12 volts from the power supply? did you check the power supply caps? post picture of the inside

[Shinju]

Re: Westinghouse LTV-37w2hd was working, now turns on and halts on W logo or Blue scr

I put it back together, I am not sure this is a power supply issue. The tv turns on with no hesitation. The messed up part was when I first got it it was working fine, HDMI And audio on all inputs, the second I hit the menu button to tinker with the picture settings is when the original mainboard took a shite!

Oh well, it's just a Westinghouse it actually had a pretty nice picture and sound for a lower end panel.

I do however have another revision power supply from a donor LTV-37w2HD guess I can try that and see what happens.

do you have an multimeter and a soldering iron? Im sure you will need it, this is a older model TV and my first guess will be bad caps on your power supply.
