Telefunken TLCD-40FHDB dim picture Repaired

[Grunder]

Thanks guys, after reading up on your forum, I have now been able to repair this set that i would normally have written off as a faulty panel.

the tv came in with a dim display, there was cockroach faeces along the inside of the cabinet, so i decided to open the panel and have a look. Photo 1 shows the roaches, however i dont know if they caused the problem. Photo 2 shows the lamps burning dimly with the fourth lamp from the top burning purple.

Photo 3 shows the lamps now burning brightly after having replaced the purple lamp with one from a scrapped panel. (you can see the fourth lamp down seems slightly longer.).

It was a bit awkward handling the light defuses/filters between the lcd film and the lamps, but I managed to make a successful repair. Thanks once again.

Someone else had monkeyed around with it before you opened it is my guess. Looks like the set has quit a bit of hours racked up.

Looks like lots of well worn lamps.

Starting to see a couple off CCFL backlit Tv's with worn out lamps recently.

It is good to turn down the backlights level too on CCFL.

Agreed, had a 42" Cmo panel a few days ago actually which backlight was on max one burnt out lamp causing a greyish bar on the screen. After replacing it set was fine.

Thanks Budm, CapLeaker & ReeceyBurger. Yes, saw other blackened tips on cfcl's, maybe should have replaced them all one shot.

When you say turn down the backlights do you mean from the user menu, or from the factory settings?? (not all sets have backlight setting in the user menu.)

just set the backlight to 50 or 60%, doesn't matter... most of them TV have it adjustable in the users menu. I've been doing this since ever LCD came out. I never had a backlight fail on any of them yet.

Thanks CapLeaker, sets gone back already, will check this adjustment in future.
