The backlight inverter which is also part of the power supply needs to be replaced. If you feel comfortable you can replace the blown capacitors on it.

Black screen after five minutes of watching. Audio is fine but no video.


What would need to be done here is some voltage tests on power board when set is working and then again when it is not, also a valuable source for some parts:

i have a samsung 32" that went black and made weird noises... it had a blown capacitor, shown here in the upper right corner, i just bought a entire board for 40$ from shopjimmy.com rather than dealing with samsung service, which i hear is way more expensive. its very easy to switch the boards. zelmer05.jpg

I have a ps50Q91HD plasma and have sound on inputs but no picture at all just a black screen, does not even come on at start up of TV.


Check if fuse F5700 is blown. Replace if necessary and then replace C5709 if fuse is blown.

Let me know if it works. If not, we can check other things.

The backlight controller is most likely faulty. It could be bad capacitors again, or the inverter board itself may need to be repaired - possibly faulty inverter(s). Try shining a torch close to the screen and see if you can see anything on the screen.
