          Can't tell for sure but it looks as though the two large capacitors on the top right of the power supply are bulging. They should be flat on top not bubbled. Those feed the primary voltages coming off of the psu to the X-main and Y-main so if they are bad then your voltages to those boards will be bad too. That will lead to a bad picture or eventually no picture. Replace those if they are bubbled and that should bring your voltages within spec and fix your problem.

                      thats definately the symptoms of a main panel logic board to me.

                              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...

                              Magnavox 27MS5402/17 CRT - no picture, flashing green light
                              by sudz28
                              I'm going to assume my beloved Magnavox CRT is toast, but also figured maybe this was a good opportunity to dip my toes into he circuitry waters and maybe learn something new. Also, I don't want to trash it if it's a fairly cheap/easy fix!

                              My 20-year-old Magnavox has gotten me and my kids through many a gaming console change and worked great up until the other day. Following a long distance move, it sat in our garage for a year and now that I brought it in and turned it on I get no picture; instead, a green light blinks on the front of it; 7 flashes, one long flash, then 3 more...

                              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                              ...
