    When it fails to turn on do you notice any power light blinking or such? If so, count the blinks between each pause.

      Like Tom asks, blink code? The C2 series SS boards seem to short out , Check for shorted Vsus line on TNPA5072 SS, Q001,Q002,Q021,Q022 short, RJP30E4 IGBTs.

      Could be SC, need more info.

        Usually if SC LED lights up the MID ERC voltage is good so it is sustaining the panel at least briefly, unlikely to be dead short SC.

          Yeah, I'm expecting SS most likely. Too soon to call. Could be a number of things.

          Massive electrical storm here 3am, yippee. Who needs sleep?

            If I disconnect c1 and c2 data drivers the light on sc board stays on and my 15 volts don't go away

              You may have a bad panel. Try repeating the test but with each ribbon going to the panel isolated and C boards both connected. If it doesn't die then power off, connect some ribbons randomly, repeat until you isolate the failed one. If one is failed, the panel is toast, unfortunately...

                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...

                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

                After all of...

                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...

                Problem

                This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                by howardc64
                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
