I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

The power and inverter boards are combined in this model. If you inspect the three transformers that power the lamps you will most likely see that one or more is deformed (looks like it is slightly melted). You will also notice that the board under the transformer is discolored due to heat. This board is also known for bad solder connections. The actual repair would be to replace the transformer (T1, T2, or T3) but as of writing this I have not found that part available without having to buy the complete board.

hi,

The best and the only solution to fix this problem is to call a tech and get it serviced or if it is still under warranty just get it replaced.

Few troubleshooting steps you can try:

1)Do a hard reset by unpluging all the cords for 4hrs and then plug it back.
2)The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.

Goodluck,
Please don't forget to rate the solution

When tv turned on will get apicture for only a few seconds then screen goes black, but wil continue to have audio. Cannot pull up menu on tv either


Hello.The screen goes black means that the backlights of your LCD is not working.Maybe the problem is the power supply or the driver board of the backlights.They shutdown because there have a shorted parts on the circuit or power supply. Did you try to reset the power and turned on and get a picture or every time that you reset the power it will get a picture and the picture goes black?

Sharp LC37D44U Power LED was flashing green. TV would turn on, channel indicator shows in upper right corner, sound good, but screen would be black. Channel indicator disappears but screen is still...


I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.

Your model has a maximum resolution of 720p. What you might want to do is make sure that both your cable/sat box and game stations are outputting at no more than 720 resolution. It's easy to assume that all HDTVs may accept a higher signal, and while they might, some of the scene changes or handshakes may make that operation cause the symptoms you describe.

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
