    RCA 42PA30RQ - Sound but no picture. Clicks multiple times

    I was recently handed down a 42" RCA Plasma TV - model 42PA30RQ.

    Bad storm caused the power to go out, and since then the TV has had no picture but the sound still works.

    Clicks multiple times when turning on, and clicks once when turning off.

    Took off back cover and:
    • Disconnected the Y-sustain board - still clicks when turning on / no picture.
    • Disconnected the X-sustain board - still clicks when turning on / no picture.
    • All capacitors look good - no bulging. Don't see any burned or damaged components.




    I'm very new at this and don't have any tools to test the voltages or anything like that. Would it be best to just purchase a Y-main + Y buffers + X-main and be done with it?

    Is it worth it to keep a plasma TV like this alive?

          From a quick search on other forums it seems the problem got replaced by changing the Y-Board.

          Some other individuals recommend changing both the Y and X main for it to last longer.
          Good luck!

                  Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
                  by TR103
                  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.

                  - without cable between mainboard and lcd panel and with a jumpered...

                  Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                  by Mgiffune
                  I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                  I ordered a supposedly ‘new' Tcon board this time, and                  ...

                  Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
                  by Ierwin
                  Hello everyone,
                  Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
                  The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
                  He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
                  I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
                  Anyway I still fully expect that there has been something seriously damaged...

                  Samsung UN70NU6900F no picture and no sound
                  by jchang
                  Hi all

                  I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



                  Symptom:
                  No picture no sound.
                  When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
                  No sound at all.



                  What I tried:
                  1. I tried unplugging the left or right ribbon...

                  by ChaosLegionnaire
                  so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

                  i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
