The picture and sound come on then a few seconds later the picture goes off to black screen and sound stays on can you help please


hi,
Is there is any light in the screen at the time picture gose. If not, then Backlight inverter is faulty. All lcd tv have backlight to light the pixels. If you watch the screen very near then you will be able to see image on the screen. First of all check is there is any budged capacitors in the power supply. If there then replace it will solve the problem. If no then check the inverter board. Do on thing check the fuse in the inverter board. If the fuse is faulty then replace it. If the fuse blews again then the inverter board is short you have to replace invereter baord. It is not possible to repair the backlight inverter. You have to replace the board with a new one.Have added the picture of inverter board and budge capacitor for your reference. If you need any more assistance feel free to contact me by Fixya.

Have no picture but there is sound. what can be done?


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.

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 .

Samsung plasma all black screen


Black Screen come from three areas. 1- Power Supply Board 2- Inverter Board 3- Processing Board on the LCD. Since the Power Supply Board was replace, it easy to troubleshoot where the problem. lies If you cannot get the backlight, then its the inverter board. If you can use a flash light on the TV screen and can barely see the images, then the problem is indeed the inverter board. If you cannot see any images when using a flash light, then the problem comes from the LCD processing board. Let me know if you have any success. Mike
