Or you can send the power supply board to us to have a look and tell you why does it keep blowing capacitors.

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.

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:

Possibly capacitors on power supply PCB have failed. If you are competent in electronics a visual check could reveal problem.

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.

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.

I have samsung 40" LCD tv and it's happening the same thing. I turned it on and it last for 5 minutes and the screen went back but the audio is fine. I turned off and turned it back on it worked fine but an hour later it happen again.
