    panasonic tx-p50gt30 8 blinks afrer 7 blinks repair

    Hello again.

    I have a little problem with my tv: it had the 7 blinks failure, and I repaired the SC board. After that, it starts for 1 second and goes to 8 blinks. Everything on the SC board looks to be fine but I discovered that I have one shorted transistor on the SS board, Q102. I have a new one but I am wondering if it would be better to replace also IC 191.
    I did not check the SS board before the 8 blinks. Do you think it's possible that it went off together with the SC board or it died after my repair?

      You should be fine with replacing Q102 only. I've had this fault myself.

          Ok, thanks. I'll give it a go.
          Have you found the cause of this double failure?

              Just the loose screws that mount the boards.

                  Yeeeee! It's alive!
                  It was only Q102 on the SS board.
                  The SS screws were not loose. On the SC yes, they were loose, almost all of them. I had some screws with washers and replaced all of them.

                      Good job! Those damn screws have kept a pretty good supply of cash coming my way.

                          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                          by Tynan Dill
                          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                          Upon bringing it home and plugging it up, it showed a standby light.

                          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                          The screen seems to blackout and stay black, but with a flashlight I can see the display.

                          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                          Assuming...

                          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...

                          Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
                          by sam_sam_sam
                          I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

                          This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

                          Panasonic TC-P54VT25 No image. A or D board?
                          by canadaboy25
                          I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

                          The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

                          I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...

                          Panasonic P50VT20B Plasma 12 Blinks, Power Supply or A-Board?
                          by Biruslapio
                          Hello, I've had this TV for 3 years, 2 years ago it stopped working signaling 12 Blinks, SOUND_SOS according to the service manual.

                          It has no VSUS or VDAT, and P15V has 1.0V instead, the same 15V goes to A board. F15V is ok and other main voltage rails.

                          It seems the power supply is defective, since unplugging D20 ribbon cable that goes from D-board to SC-board makes the behavior change, the TV stays on, there's no image nor VSUS, but 15V reads 2.4V, high enough to not trip the SOS 12 blinks, so it stays on, fans do not spin but I left it 2 hours, green led lit up...
