  8. Hi, I have a Samsung 50” plasma, model number PS50A456P2DXXU serial Z5GF3STS200897V.
    The tv was left on standby for 6months without use. When I eventually went to turn it on there was no picture. I have taken the back off and tried reconnecting the ribbons and giving it a good clean but no luck. There is a green flashing light when on standby so I guess there is no issue with power. Any ideas?

  46. hi, I have a Lg plasma TV 60pg60f-ua . On the upper right part of the screen there is a white square with colored lines going down in it. Rest of the screen is showing fine. On and off just find, no blinking lights or such. Where would I look first or most likely problem to check. could it be the logic control board or main board ? Power board is fine, Ran a meter on things and I just cant locate the problem. Didn't find any thing wrong on the YSUS board or the ZSUS board. Ribbons seem fine, looked at the ends of them all and reseed them in place. Any directions you could give me to look for or test ? Thank you.

  47. Lg 60ps11 plasma. The picture will come on for a little bit (varies on how long) then it goes black but the sound still plays. What could be the problem? Sometime it’s only seconds before it goes black but the sound always plays

  48. I picked up a Samsung Plasma Model# PS42B4302D from my friend. This unit had multiple issues. Pretty much all the boards, i.e. Y-Sus, X-Sus, buffer boards had blown up MOSFETs and diodes. I have been repairing electronic gadgets and computers for a few years, but I have never encountered a device with so many faults.

    Ideally, I should have abandoned the repairs and recycled this TV, but something prompted me to troubleshoot. And guess what, after changing the MOSFETS and other SMD diodes the TV is powering up with constant voltage (VS: 207VDC and VA: 54VDC ) readings.

    However, I noticed that the set displays the OSD, but as soon as on pressing any button on the menu, the TV shuts down. If I don't do anything, then OSD keeps on showing and the voltages are constant. I believe the logic board has some issues as well. Since I don't have the schematic for this Plasma, I am wondering if you can shed some light on which SMD component can be suspect? Repairing this TV has become fun, but wasting more time on it is not worth it.

    I am thankful to anyone in advance for advising me on what I should do next.

  59. I have a samsung 64" plasma tv pn64d8000ff. With the x sustain board and ribbon cable going to the y sustain board unplugged i get all the correct voltages. When i plug in the ribbon cable the vs and va voltages drop. When i plug in the x sustain board i dont get the va and vs voltages. Possible bad x sustain?

  60. I have a Samsung PN43D450A2DXZA.  Unit turns on using the remote control.  A brief (<1sec) ~1" scruffy looking white video band shows at bottom of screen.  I then hear the startup tune, but no video ever shows.  The42/50DH LJ41-09475A LOGIC MAIN board has LED2001 that glows green for 5secs, off for 2secs, and repeats this pattern.  I do not know how to interpret this.  I did change out CX818 and CX823 on the 42HD PSPF271501A (BN44-00442A) POWER SUPPLY board as those had leaked.  I did disconnect the Y board from the POWER SUPPLY board to see if they would change LED2001’s pattern.  It did not.  Not sure what I’m going after at this point and have exhausted my technical diagnostic abilities.  Thank you in advance for your help.
