    Problem with my Plasma TV LG 50PB560B

    Good evening, I have a plasma TV LG 50PB560B that did not light anymore. There was just the red LED on when I turned it on. I suspected the Y-SUS card. Indeed, controlling, I found a transistor 30F133 shorted. I replaced it with IRG7R313U. When I turn it on again, the screen lights up and then stops almost every second and it's repeated. No OSD display, no sound either. The voltage Vy oscillates between 0V and 5V. Here are the few pictures of the TV that I could take.
    Thanks for your help.

              Problem with LG Plasma 60PM6700 - Random power downs
              by theone111
              I have an LG Plasma TV 60PM6700 for the past ~12 years.

              In the last ~3-4 months I have been having some issues.
              1. Problem: It started with random picture disappearing (sound still worked).
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait a few seconds before turning it on again.
              2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
              3. Problem: TV shuts down

              panasonic TH-42PC77U plasma television half screen problem
              by renech
              hello,
              I hope someone on this forum can assist me.
              I have a panasonic TH-42PC77U plasma television.
              the lower 1/2 of the screen has become flaky....in and out, then finally goes black and you can only see the top portion.
              i have performed the reset to default settings quite a few times. Panasonic recommended..did not believe this would help...it didn't.
              I have removed the back panel and looked around for something obvious...burn marks in a board, etc....nothing obvious...
              I have read some posts that suggest the problem is related to the boards on the left...

              Thinkpad X1 Carbon "LMQ-1MB 12298-2 48.4LY26.021" VCC3M problem
              by Zeonalbasta
              i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
              The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...

              Hi. I have a problem that has been going on for some time (2-3 years). It's hard to explain what it really is. Sometimes, my computer stops playing music, stops videos (starts buffering on youtube), there is no sound in games and when I minimize the game window and return to the game there is a black screen with window borders...

              Lenovo T580 - LCD Panel problem - error 0288
              by perzyk23
              Good morning,
              I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....
