Re: lg 47inch picture fault

looks like panel fail to me,bad tab bonds

try re-seating lvds cable after cleaning contacts both ends with iso alcohol

flex gently the screen,does anything change?

still could be t-con though

can you show a picture of the screen,with the menu up ?

I'm going to agree with panel, and I've never had good luck repairing LG panels with tab faults :/. Has to be zero for three on success rate.

Well--trust me to disagree!

I had a 37" LG 1080P set on Sunday with exactly that symptom--Working well for up to half hour, sometimes only 10 mins from completely cold. Strange thing is--certain scenes, like computer generated stationary images (intros to programs etc) were mostly stable--only when the pic changed to motion would it go beserk!

It was the Mainboard at fault.

Changed the T-Con, no difference, replacement (Philips-LG) mainboard cured the fault completely.
It was a LG 37LF66 summit or other....
