    Daytek EPT-4202AN Picture cuts out

    Good day everyone. I have a Daytek plasma TV model# ept-4202AN that is giving my friend picture problems. The tv set works great for about an hour, then the screen turns into red pixels and fades to black. Sound works throughout. If i turn TV off for 15 min or so and turn it back on the picture works for about another hour then kicks off again.

    I have taken off the back panel (sorry no camera) and can't see any visibly blown capacitors. The heat sink located on the YSUS board seems to be running much hotter than the heat sink on the ZSUS board, not sure if this is root cause of problem.

    Any advice would be greatly appreciated, as i said i have checked for visibly blown capacitors and have verified the fuses are still working properly with my multimeter. I can't seem to find any information on this TV brand on other websites, so hopefully the tech gurus here will be able to advise. Am i looking at a YSUS board replacement or is the issue an IRC or capacitor?

    Thanks

      Had a chance to do some further testing, and it appears that I have 7 blown surface mounted radial capacitors. They are all running at 220uF and 25V, and are all located on the YSUS board. Will these lower resistance capacitors cause this problem? My typical experience with the capacitors is a work/don't work scenario, not a work for a while and cut out style.

              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 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...

              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              ...
