    Panasonic TC-P42S1 no picture no sound.

    I have a 42" Plasma that does not have a picture or sound. I have done little testing on it and if i unplug the top right board then the tv will power on and have a picture. Its a bad picture but its there. If the board is plugged in the it wont turn on at all and just flashes 10 times. I have not done much to it, I still need to blow all the dust off. lol.

    Its a TC-P42S1
    heres a few pics.

      Sounds like you've isolated the problem to me as bad SS board.

          Picture purplish tinted, somewhat faded, and/or very dim? SS is dead.

              Yep thats what it looks like. I Know the SS is dead but i would like to try to Fix whatever died on it. Does anyone have a trouble shooting guide or a service manual for it.

                              If that's all that's shorted how lucky are you. At least it's off the shelf available.

                              The schematics are all you're most likely going to find. SS boards are usually cheaper than SC to buy.

                                      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.

                                      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

                                      Hi, I have a Samsung UE50TU with:
                                      - sound and backlight, but no picture
                                      - when it arrived, it had a picture for a few seconds
                                      - it keeps rebooting
                                      - without ribbon cable between the two panel boards, it does not reboot but I have no picture
                                      - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
                                      - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

                                      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                                      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                                      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
