This tv had a shorted X-SUS board. Replaced the board and the TV worked fine. I put the back on and then I turned on the tv. No picture. I took the cover off again. When I powered up the tv, there was a loud buzzing sound which seems to be coming from the Y-SUS. Is this something that can be repaired? What causes the buzzing. Is it possible it is a bad panel since the xsus was shorted out originally.

Re: Samsung PN51D550C1F buzzing sound
These use combined ERC (Ymain and Xmain recovery linked) so if the Xshorts it can damage the Y and the same time. Have you checked the Ymain for short circuits on the Fets ?Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only.

Hi all
I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.
Symptom:
No picture no sound.
When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
No sound at all.
What I tried:
1. I tried unplugging the left or right ribbon... -
Hello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged... -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
