If your power light is coming on and you can hear sound.It should be your inverter.The inverter works like the starter in a florescent light bulb.Your backlight isn't coming on. Try ebay by typing inverter and your model number in their search.

Picture went out on 2-year-old Samsung TV model UN50EH5000F. I have sound and full backlight but no video.


You have replaced everything that could have gone wrong - except for the video Screen itself. Check the connections (ribbon) to the screen for oxidation - use eraser to clean.

Sounds like you've replaced everything but the backlight itself!
If you have another working unit, connect this LCD panel to the working unit and see if it works. If it's still dark, you need to replace the FL tube (backlight(s) ).

Have no picture just sound


Your video board is defective.The sound indicates your power supply is working.Often the inputs are to blame and no signal is getting through.If a picture appears on TV mode then the problem is on the inputs-it could be loose and needs resoldering the terminals.But if it all happens on all functions then you need to replace the video board.In comes in between the input board processor and the video processor(the board that is terminated to the Plasma screen).

Can i change the sound board for samsung plasma ps 50c91h in my home and what will be the cost of the board, the main problem is when we increase the sound above 17 point the sound goes off, please help me...


There is no sound board in your TV. You need to replace mainboard that control sound and video.
Before having replacing that board, try to use button to see if the same problem happens. If there is no problem with buttons, the cause from the remote control or sensor board. Main board costs $300 up, you can call Samsung and order or go to their affiliates.

Sound but no video HPT5054 Samsung


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.
