    LG 42PX11 no picture

    Been offered a LG RZ-42PX11 42" plasma for £50 complete with remote, no picture, just a black screen which "fades" to grey after about a minute

    Does this sound like a panel problem?

    Don't want to put any more money out on TVs at the moment really, but this one seems too good to miss if it's repairable.

    Cheers

    Jim

    Huge NO. At least 7 years old (released Nov 2004) and 852x480 resolution.

      Ah! ok.

      Should have checked the specs, wasn't even aware such a low spec plasma had been made.

      Thanks for the heads up

        I can purchase a new tier 1 name 40 to 42 inch 720p plasma/ 1080p LCD for about $400. With Boxing Day coming up, that might drop to $350 or so.

        IMHO, the fair market value for a WORKING 7 year old plasma 852x480 should $100 or less.

          I bought a 480p 42" plasma for a very good price - £2.19 - and was able to sell it on for £120. Had three bad caps, big 560u/250V ones on the Vs, rare failures...

            Not bad for 30 mins work

            It averages out though when you get a bu**er of a job and it takes days to sort.

            Good work though

              Cost £20 to get the components for the TV from the US, though... but still was nice to fix it.

                Well, I was off a bit. One boxing day ad has a 43 inch Samsung Plasma 720p for $299 CDN (taxes not included). Limited quantities, but it gives you an idea what the used market should be priced at.

                  Ugh. Don't even get me started on low end Samsung plasmas... There's a reason they are $299.

                    SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
                    by JJAAMM
                    This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                    Problem
                    TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                    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...

                    by KYBOSH
                    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.

                    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)...

                    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...
