    I have a Samsung LE32B450 that has a crackling sound and picture freezes/pixelation/green spots. It does it whatever input it's on. I've tried opening it up as I believe this can be caused by bad capacitors on the board but I can't see any that are bulging or leaking. I've also seen varioius posts from people saying to replace either the main board or the power board. I've found both on ebay.

    Power Supply Board LE32B450C4W (BN44-00260A) TV PARTS | eBay

    SAMSUNG LE32B450C4W BN94-03130N MAIN AV BOARD | eBay

    Can anyone tell me which one is the more likely culprit so I can try that one first?

    Thanks.

    Hello, I would like to ask you something. I see you have got Samsung LE32B450C4W. I have got the same, but I have accidentally changed panel type in service menu. Now my screen is Black.
    I know how to clear EEPROM, but I do not have original values. Do you have screenshot of service menu values please?
    Thank you very much in advance, Jan
