    LG 60" Plasma TV Picture Problem

    Hi,

    My TV has just recently started to lose its picture for a split second at random intervals. Say, on average, 6-12 times a minute. The loss only lasts for a fraction of a second - so I guess you could call it flickering? But it makes watching TV next to impossible!

    I originally thought that it may be caused by the Rogers NextBox 3 HDPVR - which I just switched over to from Bell. But I have tried every conceivable thing (connecting through the AVR vice direct to the TV / tried the standard def box that I use upstairs on this TV / even hooked Bell back up) to confirm that it was not the NextBox 3 that was at fault - although the timing is suspicious - never had a problem with the TV for 5 years using Bell and now within a month of switching over to Rogers this?

    Weird thing is though that if I leave the channel on the On Demand for Rogers the picture is fine and doesn't flicker?

    I did replace the Y-Drive recently to correct a loss of picture on the bottom of the TV (about 4" horizontally at the bottom). This went well and the TV was working like new again.

    So what do you think can be causing this loss/flickering?

    Also, if I have to get a new TV which brand of Plasma would you recommend - I will be getting an extended warranty this time!

    Thanks Much.

      It could be a bad Y-Sus. I'd open the TV and monitor voltages during the flickering. As far as a replacement TV is concerned, which I don't think will be necessary in your case, Panasonics are the highest rated TVs.

          Hi CapKid,

          One other thing I forgot to mention is that I run everything through an AVR to HDMI 1 on the TV. All other connections (Xbox / Wii / Patriot BoxOffice (for movies from computer)) play flawlessly - no flicker. Only the cable TV (NextBox 3) causes this flickering? Which doen't make sense to me?

          Thanks for the Panasonic recommendation - this is where I may be going this PM.

              Sounds like I would rule out the tv as the fault if no other input can reproduce it. Is the AVR an Onkyo by chance ? They are known for failing capacitors on the digital/hdmi board and some inputs start acting up before others.

              Maybe try switching around your inputs see if the fault follows the input.

                  Yeah, the TV seems to be fine. If you want to buy a new TV, just say so

                      Hi,

                      Yeah, I've tried all of that switching (the AVR is a Pioneer Elite). I ended up going out and buying a new TV (Panasonic 65" with extended warranty to 5 years). I will take this TV apart and start exploring (again) so expect a new post as I start to fiddle around and need to know how to "X" or "Y" and where is "Z" etc.

                      Thanks again for the help and I do hate parting with the money!!

                              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.

                              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)...

                              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...

                              Hello, I need your help for a failure on a laptop:

                              It's a Packard Bell Kayf0, motherboard LA-5021P, Rev 1.0 with graphic issue.

                              I received this pc because it was turning on but not displaying anything, the fans are running normally and all chipsets heat up on startup but no picture on screen, no backlight either. I noticed that ENAVDD and ENVDD are not present and that there is no LCDVDD on the connector. I didn't check the screen because, maybe I'm wrong, but if there aren't these signals, even if the screen is good, it can't display anything? I tried heating the...
