    Phillips 50" Plasma - 50PF7321D/37

    Hi All,

    While watching TV at very random times the picture goes black. It still has sound and appears to still have back lighting. Not sure if this will help but when it happens all I have to do is smack the back of the TV and the picture comes back. Also sometime I get the rainbow of vertical colored lines just before it blacks out.

    I opened her up yesterday and found what I believe to be two bad caps. One is easily fixable and seems to be just slightly raised. The second (left arrow in photo) I can not see very well because it is under a heat sink. It apears to be leaking slightly. I am looking for any sdvice you might have and links to where I can purchase these capacitors.

    Thank you for any help!
    Kevin

      Here is one (and can use as an example) for the first one
      http://www.digikey.com/product-detai...2735-ND/613719

      They both look bad (from my perspective) but the fact you can hit it and it work again is strikingly odd. (sorry :P)

      But on a serious note, I would just make sure all your connectors are seated correctly, especially ribbon types.

          I'd replace all of them except the big input caps, they're Samwha...they're all doomed to bulge eventually. You can leave those Samxon caps those should be good. List all the specs of the caps so we can give you proper links

              Yes it is very weird! 95% of the time the TV works perfectly. But it is annoying to have to get up once or twice a day to smack the back of the TV. Yes I know this sounds lazy but its hard when you have a sleeping baby in your arms... Thanks for the link and the advice! It looks like that one is perfect for the first one. The one under the heat sink unfortunately I can not see so I will have to wait till I have time to really take it apart before I can give the specs on it.

                  If you hit it and it comes back on then it is likely a loose connector or cold solder joint.

                  Leave the back off (well away from kiddies) and when it does it again slightly flex each circuit board to see which is the problem. Use a bit of wood to do it.

                  Then when you have found the board look for cold or poo solder joints.
                  Do NOT touch heatsinks when testing for voltages as they may be LIVE!

                      Thanks Gill71984, I will have to try that. The trick will be keep my 4 year old away from it.

                          Oh make sure the dimensions are correct for the capacitors - that's the only criteria I couldn't match but it'll be slightly annoying when the cap is taller than the heatsink lol

                              Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
                              by KYBOSH
                              Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
                              No picture but you hear the TV static (white noise) playing loud and clear.
                              The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
                              But it seems they didn't get too far and just left it.

                              When I first took a look I was amazed at how pristine the inside looked.
                              Its as if the TV had been in a time capsule.
                              Caps looked like they were just pulled off the self.
                              Copper coils had no sign of corrosion on...

                              Saved this beast from the landfill this weekend.
                              Manfactured July 2013 in Mexico.

                              I love working on plasma TVs.
                              Its been a while but I was lucky enough to find 2 this week.

                              The TV powers on and stays on but no picture. Havent checked for sound yet.
                              No bulging caps although the insides are pretty dusty and the boards are discolored from many years of high heat.
                              Will start troubleshooting tonight.

                              Phillips 58PUS7805/12 No Picture
                              by Bloopeta
                              Phillips 58PUS7805/12, was told it had sound no picture, sometimes picture would come back then go again?

                              From what I have seen myself, its just blank illuminated screen. Tried unplugging each ribbon cable from Tcon in turn.

                              When one is unplugged, I get half sceen, clear picture.

                              With other unplugged, get half screen but with thin horizontal lines

                              Any ideas? Or is it likely a bad panel?...

                              Customer said if he keeps it on for a long time, turns it off, and later back on, it takes 10 minutes to get to proper brightness. Is this just a cap issue? I didn't have time to take it apart I was just there to drop a repaired laptop off

                              T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
                              by Tr0ll
                              Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                              The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                              Original T-con:
                              Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                              First replacement T-con:

                              I thought it might be t-con and ordered new t-con from china(supposedly tested)...
