Re: Samsung PS58B685 (like pn58b650). Sound but no image.

Update:

Got my used Y-main and on X-main from eBay this week, and just got around to try them.

I meassured the Y-buffer again for shorts, but found nothing wrong, so I crossed my fingers and fired it up. The picture is back and everything seems fine, and as a nice bonus the loud hum is gone :-)

Thanks for helping out!

Thanks for your anwser!

I just bought a set of used X and Y mains on eBay. Are there anything else I should check or replace while Im at it?

I guess I could double check the Y buffer boards for shorts, and also check for shorts between + and - of the input. But besides that?

Hello all

I could really use some help with this Samsung Plasma TV.
It has been running fine for 6 years until a few days ago. Then the picture just disappeared. Screen went totally black, and the usual loud hum was gone. Audio still worked though.

I took it apart and started debugging. Power supply board seems to deliver the voltages written on the connectors, and the logic board blinks every second. All caps looks fine! I then looked at the X and Y-mains.

I found 2 pico fuses that was blown. One on Y-main, and one on X-main. I have attached pictures...
