20 Most Recent LG 47 in. Flat-Panel LCD HDTV Questions & Answers


Hello
Just unlug the TV from AC mains wall socket, and replugh it after 5 minutes and see whether it helps you. If not, open the TV, and check the fuse on its power board. If found blown up, never insert an other one before rectifying the short in it. In most canses, power board need replacement.
You haven,t specified the exact model number of the TV. If it were there, I may have suggest the exact power board, and its picture that will help you to identify the same. OK.

hi,

You have to check the back light of your lcd TV. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

first of all check all the electrolytic capacitors in the power supply and back light inverter board.If available then replace these capacitors first.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .
ok

Is this TV a flat panel LCD TV or projection TV?
Flat panel LCD TV does not use projection lamp. Please verify with model number.
