I have a Samsung UE40C8000 TV that is about 6 years old. It is a 3D TV, so the 2D picture was of decent quality and that was the main reason I bought it. The picture has been playing up, with fine horizontal lines appearing across the whole screen (so like watching TV through a venetian blind - though sometimes it goes a bit 'tartan' with vertical lines too). Initially this would clear after 10 minutes, but then it took longer and longer and it now seems permanent and so unwatchable.

I would like to have the TV repaired and keep it if possible, but not if the repair is prohibitively expensive. Does anyone have any experience of repairs with flat screen TVs - worth pursuing or so expensive that they are not worthwhile? I seem to have a Samsung service centre very close, so would likely take it there..

Many thanks

Just saw the other Samsung TV thread - interesting that it is the same series and the same age. I have had already had the back off mine and couldn't find any swollen capacitors...

Could be something as simple as a cracked solder joint or busted PCB track which re-makes itself as the TV heats up and things expand.

That might be solved by re-flowing the PCB, but you might also completely fry the board if you're not careful.

If there's nothing obviously amiss on the inside and you don't want to risk killing the unit completely, then it's probably off to the service centre.

This might sound like madness but I have repaired to TVs with this method, a
50" LG and a cheapie from Asda.

LG wouldn't recognise any HDMI inputs and the cheapie had an unstable picture and no sound. After a flick through the internet the general consensus was dodgy soldering. Fine made sense. The cure didn't, put the offending PCB in the oven at 200c for 10min.

So that's what I did. Put a sheet of a4 on a baking sheet and then the PCB. Into the preheated oven for exactly 10min then oven off door open and leave it to return to room temperature.

This worked for both my faults. The family thought I was mad but who cares.

If your options are bin it or get a new one then definitely worth a try IMHO.

Sounds like a faulty screen. Price on screens has dropped, but will still be quite expensive. Worth giving a Samsung service centre a ring to get a price
