    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.

Koss KLD2700 LCD TV no picture


http://www.fixya.com/support/t860220-screen_blank
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
