    Picture flashes on for 1 second then the screen is black. Sound is fine

  • lenmartin Mar 22, 2009

    I am experiencing my second problem with this Samsung model.

    billn352's fix worked for my Samsung when it would not turn on--NO VIDEO AND NO AUDIO. The fix worked for a week, then I lost the video but RETAINED THE AUDIO. I removed the back--the caps I replaced and the other caps on the power board appear to be fine.

    So my current problem is carolina602's problem and not billn352's problem. Is it a power board problem or a video board problem?

Faulty parts on PS board , bad press for Samsung

Because the Samsung LNS4051D would not turn on and the power LED would blink 4 times and the relay would click and this would repeat again and again. I replaced power supply board parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors, three had their tops bulged up slightly that I missed on initial visual inspection. After seeing the reports of problems with these caps on http://www.fixya.com/support/t1336881-will_not_turn_or_off , I replaced them with Radio Shack part 272-1032, 1000 uf, 35v. They are slightly bigger, but fit OK. TV is working fine now. Cost was 4 x $1.59 = $6.36 plus the time. I saved between $100 to 300 in the process of either replacing the board or getting the unit serviced.

42 inch LG Plasma TV - Lost picture


Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

As in almost all lcd type tv/monitor the backlight will go out and the inverter should be replaced at the same time. Your cost about 50.00 if you do it yourself.

Take care

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
