    GT-30 shuts off and 8 blinks when vivid mode selected.

    Hello everyone, hope someone has some insight for my 2011, Panasonic GT30 TV. At least give me an idea where to look.

    Problem started with the 7 blink issue (would not power on), then I had replaced the SC board (bought a supposedly new board from a china supplier via ebay). when I replaced this board, the 7 blinks went away and the tv powered on - but with picture issues. the TV is working to some extent, all inputs work, however, the colors are quite intense making for a bad picture, and when I select vivid mode, the TV will shut down and give an 8 blink SOS. I can reset and repeat this. One other note, it appears that the 3d picture is OK (however, I do not have 3d glasses to confirm), but the over-saturation goes away in 3d mode. Also, the general color tests in the service mode appear to be fine. Basic text appears fine as well. Please let me know if you have any ideas, or direction on this. I have not checked any TP's yet, rather taken the board swap approach. Thanks.

      Don't have any ideas at the moment but can we get photos of the image issues, and the boards installed , preferably closeups with the sc,sd,su set and then the other side of the SS.

          Also if you have the old board still there's a place that does rebuilds. Could be worth sending both boards, 1 for repair and the other they may run up for you and confirm if it's good or not.

          the other question is did you get the exact same revision board? I have a feeling someone had some unusual image issues and in the end they had the wrong board.

          So the more detailed info you can give , like model, photos of both boards also showing the part numbers and there's normally a white sticker, also has the full part number.

          Plus a photo of the display fault.

          A rebuild is in the order of $80 sending your old board in

              Did you ever fix your issues with the bad color? Also, what was the VS voltage on white screen?

                      by Biruslapio
                      Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.

                      Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner...

                      Panasonic TC-P55ST50 8 blinks then no blinks
                      by Andre Gilbert
                      Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here๐Ÿค”?
                      Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting ๐Ÿ˜‚.

                      Optiplex 3050 micro 2 blinks followed by 3 blinks issue
                      by Taurus12
                      Does anyone have an idea of what might be the issue with my 3050 micro? I have tried replacing new cmos battery but still the same

                      I am not sure if its the powersupply that I'm using is the issue since its the original powersupply. its a laptop powersupply with the same specifications with the 3050 micro so i guess it should be fine.

                      i also tried replacing the bios but with no avail, everytime i try another bios it gives a different blinking lights

                      Any recommendation on what I have to do next? Thanks in advance

                      I have a really weird problem, this motherboard was working normally, someday it just started and all fans were running but didn't want to post, tried resetting bios, checking CPU and it was getting warm tried external gpu, flashed bios with programmer, but same problem.
                      Next day after several attempts the board goes into protection mode, no more staying on, I turn on the PSU fans starts directly turning, it used to not start until I press the pwr button, now it starts directly and fans spins, and shuts off after 3 seconds sometimes less, then won't start again unless I unplug the PSU and...
