could be, did you try reseating your tcon cable and ribbons? careful with the ribbons, use fingernail to pop up retainers, can check youtube tcon replace for a video, if you like.

Will need to take apart and see what the story is.

Look closely at the bottom of the black bar, it looks like an impact point.

Definitely looks cracked to me... that can't be anything but impact damage. Unrepairable.

Re: Lg 42ln543v bar in screen

Yes the screen is in bits alright.Will scrap it and remove working parts>
Sorry for the bother guys..

Re: Lg 42ln543v bar in screen

no problem at all, at least there was a conclusion, too bad about the broken screen, looks like a nice tv otherwise.

Eh, just a basic 42" LCD... if it were a KURO plasma I'd be weeping!
Still a shame, no doubt, hope that it was as-is, not like this after a repair...

Re: Lg 42ln543v bar in screen

can't seem to get ahold of any plasmas, but I like the good clear picture on lgs and sonys.

Re: Lg 42ln543v bar in screen

No not after repair so no loss really to me!!!

Trust me if you are a beginner at repairing tvs stay away from plasmas untill you gain more confidence, lots of things can go on them.

I think plasmas are easier than LCDs. You just need to know what to test. 9 times out of 10 I can fix a plasma by doing five simple voltage checks.

I find the voltage testing and short testing easy just like lcd its just alot more work as the are lots of buffers and sustain boards to test. And if you have a bad y sus repair it and the x sus is also bad it will take out the new y sus just basially alot more work.

Re: Lg 42ln543v bar in screen

Hm, if you say so. A little testing can eliminate that risk. Always use a light-bulb tester when testing plasmas on the Vsus rail.

Bad master-slave inverter can also destroy opposite inverter (had that on a Sharp LC-52XL2E... what a nightmare.)
