    Troubleshoot Samsung Plasma

    Hello newbie here.. My neighbor gave me a nice plasma to repair. PN69d660c1f.
    I found the power supply was bad. I tried to do component level repair but screwed up some traces. So , I bought a China (replacement board). The logic board blinks slow. The VS out of the PS is 319 and the VA is 5.1. When I test the vscan on the y board I have nothing. I replaced the y board and still nothing. The x board has 319. The Vs and Va are out of spec, so I emailed the company and they said it was better technology. ( not sure ?) I did not replace the y buffer board. Could that be why I still have no voltage at the vscan?

      On your plasma panel, you should have a sticker with all the voltages listed. 319 seems about 100 volts too high, and va should be around 55 volts.

          The sticker says VS 217 and VA 55. The adjustments don't work.

          From the power supplier:

          We have improved the technology and it is completely applicable to bn44-00445a,thanks

                  by m1ch43lzm
                  Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                  Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                  Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
                  by ohren
                  I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

                  I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

                  The models launched in 2018 and 2019 respectively....

                  Samsung UN65KU6290F PS board blows fuses
                  by valvashon
                  Samsung UN65KU6290F (May 2017); received from local Buy Nothing group. Was listed as "just went dead" and they wanted it gone. I brought it home, didn't notice anything visually wrong with the power supply board, looked up the cost of a new one and that's about as far as it went. Family was tired of tripping on the foot of the set so I decided to dig in and repair or toss.

                  Can't believe that I didn't check it earlier but I found the main 8 amp fuse blown. Jumped across it with a 10 amp blade style fuse and you can see that it literally exploded inside the second I plugged...

                  Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                  by Asraf Atb
                  Hi everyone,

                  Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

                  Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

                  I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....
