Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

SOURCE: TV No Picture

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

Do you know if i can use an inverter from any LCD tv, or does it have to be specific to that model? I was thinking about taking an inverter from another broken TV.

Sound ok white screen no picture


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
