Re: Samsung Plasma PN58B650 Power Cycle
@SewnNsilent
In the end I determined several components had failed in my Plasma panel but I am happy to say I have successfully repaired my Plasma panel and it continues to work operate beautifully.
By performing the tests noted in my original post and by following[URL="https://www.badcaps.net/forum/showthread.php?t=29327"]this forum thread[/URL] I determined the following components failed.
- Y-Main
- Y-Upper Buffer (upper long thin boards vertically aligned on the TVs back left edge)...

Re: Samsung Y-scan (buffer) replacement boards?
Again, to help visualize the board differences, I wanted to post pictures of the backside of the boards. My original board is on top. Also, should I be concerned with the board I received having a white residue on the back side? Is the white residue a sign of the board being used?

Re: Samsung Y-scan (buffer) replacement boards?
tom66,
Thank you for the quick reply. I have already tested the board and it checks out (no shorts). I actually used this same test to determine my lower-Y was bad.
For the sake of being thorough, I contacted several other sources regarding the different PBA numbers and only wish the replies were the same. This is what was said.

The different PBA numbers show that the part I received is a known replacement for my TV.

Samsung Y-scan (buffer) replacement boards?
I ordered a Y-Scan (buffer) Samsung Part# BN96-09760A from a company out in California (Dappz.com). The part came quickly to NY (free 2 day), but when I looked at the board numbers, these did not match the numbers I have on my board (see below).
I need to know if the board sent to me is considered a revised version to the one I pulled, since all of the screw mounting, black connectors and white connectors all match size and position. If you look at the attached picture (my original y-scan on top), there are slight differences in components and placement.

tom66,
I did remove the screws for the y-main and y-buffers so I could swing the board out and inspect the back. There are no visible signs of damage on the backside or front. As I stated before, the only time I saw smoke was after the first time I jumped the PS-ON to GND, VS-ON to 5V with 100 ohm resistors and plugged in the tv (30 seconds). Since then I've been caution leaving the TV on longer than 10 seconds while the y-main and x-main are plugged into the Power Supply. Further tests with the resistor jumpers in place would...Last edited by unkiexeon; 12-28-2014, 12:01 PM.Leave a comment:

Re: Samsung Plasma PN58B650 Power Cycle
tom66,
Thank you for the quick reply and suggestion.
Checking for shorts - meter set to auto range ohms:
Y-main Green fuse:
ground -> right side of fuse :: 2k
ground -> left side of fuse :: 30M (high resistance)
X-main Green fuse (fuse is standing vertical on the board):
ground -> right side (top) of fuse :: 11.5k
ground -> left side (bottom) of fuse ::11.5k
Since the caps seems to be taking a charge from the my meter, I held...Leave a comment:

Samsung Plasma PN58B650 Power Cycle
Thank you for this awesome resource! I would really appreciate some additional help on this issue.
I purchased my PN58B650S1F Plasma in 2009 and just yesterday (12/26/2014), the TV went into the clicking loop with no picture; exactly as described by MyEvolution [URL="https://www.badcaps.net/forum/showthread.php?t=29327"]in this thread[/URL]. I performed all steps as advised in [URL="https://www.badcaps.net/forum/showthread.php?t=29327"]this forum thread[/URL], but for the sake of being thorough I am posting my exact steps below.

Re: Samsung plasma PN58B650S1F clicking relay no picture
I wanted to add the images to my original post as attachments. Sorry for missing this request in the sticky.
I also wanted to note, I have checked all removable fuses for continuity and all have checked out.
