Facing TV Problems? Ask a TV Technician.
Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
so is your intent to try to fix this yourself? Or just finding out what would be involved?Does sound continue after startup (you'll have to hook something up to test)?
Yes, I'm here, but please give me time to respond, find parts, etc.
It is possible, but may not be worth the investment for a 6 year old set, as it is past its service life at this point and plasma technology is now obsolete. For comparison you can get a new set this size (LED) in the $400 range.
Test an input if you can, based on what you've described so far it is a bad Y main as the most likely cause. Look for the larger board toward the top left, and check the ceramic fuse there for continuity, replace and test if that resolves it. If not, replace the board: http://www.shopjimmy.com/samsung-bn96-17225a-y-main-board.htm this is the likely part but check board number on your existing one for an exact match and re-search if necessary.
No the LEDs do not, though the latest OLED is every bit as good as plasma. Regular led does not have the same black and contrast levels. The issue with the old plasmas is ability to find parts, and that even when you do fix it, all the other parts are well past the designed service life and will continue to fail, so just don't expect it to be a long term fix is what I am getting at.
The board I linked to was only about $25, so that is certainly a reasonable fix to try out.
