Re: samsung le32r73 picture problems
Thanks for the pointer. I got hold of a working psu and fitted that but the problem persists so suspicion now falls on the mainboard.
As the picture is fine for a while from cold its looking like its heat related so the 1st thing I was going to do was take out the mainboard and look for dry solder joints. Is there anything which could cause the TV to fail once its warmed up? Cheers

samsung le32r73 picture problems
Hi folks
The above TV startedhaving picture problems. After a few mins of use the picture would start breaking up until eventually it would freeze or go black
I took the back opp and 1 bad cap on the psu near the mainboard connector. I replaced that but after a few mins the cap bulged again and the picture went soon after. I replaced the cap again with a higher rated 1 and the tv worked came on and worked fine for about half an hourbut had no sound this time and then the picture went again.
Ive not had chance to take the back off again but im thinking the mainboard is at fault...

Re: lines on screen Manta LED4201
Still trying to find a tcon for the Manta TV. The con is a c6870 0328a v0.6.
There is 1 of these on ebay but does the replacement need to be not only the same part number but from the same TV or will any c6870 0328 v0.6 work in my set? Thanks

Re: lines on screen Manta LED4201
Yes, I was when I 1st opened it up and the picture was displayed though washed out.
Didnt test it after id jiggled with the ribbon cable and the screen went to just vertical lines.

Re: lines on screen Manta LED4201
Thanks for the suggestion though I still think I'll try a new tcon - if I can find one.
Scoured ebay and they seem to be rarer than hens teeth so can anyone suggest where else I can try? Also tried flattvparts, spares2repair etc.
Cheers

Re: lines on screen Manta LED4201
Hi
Still unable to upload fotos from my tablet but think it is a faulty tcon.
Having no luck tracking down a replacement. Not even ebay has them, its an e8844194v.
Does anyone know where I could pick one up or even somewhere which can fix them.
Much appreciated
Andy

lines on screen Manta LED4201
Hi
Picked up the above tv today and initially the picture came on but appeared washed out, lacking greens.
Suspected the Tcon so reseated all connections and much jiggling later all the screen displays is a screen full of multicolour vertical lines. Sound is fine.
Im having probs uploading fotos from my tablet but does this sound like a tcon fault before I try to track down a replacement or a bad panel? Cheers

Re: Toshiba 32DL934B IR sensor
This TV doesnt have an on/off button, just the remote (I hope or I'm gonna look stupid)

Re: Toshiba 32DL934B IR sensor
Thanks for the reply
Ive scoured ebay for a part and had looked at one but wasnt sure if it was the right one
I recently fixed a 26" DL series and from memory it looks identical so have been looking for an IR sensor from any DL TV's but none are listed as such.
Do you think that one will fit? Thanks

Toshiba 32DL934B IR sensor
Hi
Just bought a faulty 32dl934b off ebay with no power lights showing. I assumed it would be an easy fix with the old Vestel diode problem.
However, when I opened it up the IR sensor was missing, hence no lights.
So I need to buy a new IR board but cant find the part number anywhere
Does anybody know the board number I need to be looking for please? Cheers

lg 34px3rva
Hi folks
1st post so apologies for any noobiness
Ive been given an old LG plasma to look at 42px3rva which has the seemingly common sound but no picture problem.
I opened it up and saw a blown 350v cap on the y sus (c26 I think) which I replaced.
When I put it all back together a resistor right next to the cap glowed red and blew.
Now I cant see what value the resistor is.
So, 2 questions please
Is it common for it to be another failed component on the y sus which has caused this and if so is it worth replacing the resistor?
