Replaced the main video board
What is the make and model? Your post says that you ARE getting picture and sound. What was the original problem? What lights work on the unit?

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.
The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

One of your transformers on the inverter board are failing to sustain regulated power to the florescent lamps resulting in a dark picture. Also check the SMD fuses on the inverter board(s) see if they have blown. You will need a continuity meter to check them. You can get one from radio shack and be sure to get one with audible sound....you don't have to replace boards when you can fix them.

If you received a remanufactured board it might be defective,Or did you forget to hook back up the speakers? Sounds dumb but happens alot. Speaker wires get in the way,we disconnect them to look at a board or replace one.Often gets over looked.But I have received several defective boards.Hope this helps. Toddthetvmd

Thanks for using FixYa. As you have already replaced the Z-sus and the main logic board then the issue seems to be with the Y-main and/or Y-sus board. You’ll need to take the back off and check for any blown/bulged capacitors that might have gone bad and causing this issue. Please do accept the solution if the issue is resolved or post a comment for further assistance.
