Low vs and no va on samsung pn64e8000

[Newcastle]

Hi everyone. Great site 👍. I recently picked up a samsung pn64e8000. No power when I got it. Changed a fuse, blew a mosfet and then read everything I could find on this site relating to this particular set and a couple similar posts. I've purchased the rebuild kit from an online source and I still have the exact same issues. Low voltage on vs (4.0v +\-) and nothing on va. Green led in the back blinks on for 5 sec off for 2. Only $100 for the tv and $30 in parts. I'd like to get it going. Not ready to give up yet.

Fuse is still good after the repair? What happens when you disconnect y main? Do you get VS and VA at the power supply? To be missing VA with a bad y Main sounds odd. Va should still be there at.power supply rails imho.

It would seem the PSU is bad.....can you source a replacement from e-bay or any other source?...If yes...replace PSU....No Va is not a good sign and low Vs......transformers??

There are a lot of kits out there that have bad parts. Even shopjimmy kits contain bad parts. I would say your best bet would be to find a used part on eBay or to source the parts yourself from mouser, digikey, or other reputable distributors.

Thanks I will look into finding another board. Hopefully I can find one at a reasonable price somewhere

I was able to get my local electronics shop to order me a board direct from samsung. I should have it by Monday. Fingers crossed this was my only issue. Thanks again everyone for pointing me in the right direction.
