    TCP42ST30 6 Blinks

    Hello I have a Panasonic TCP42ST30 that has 6 Blinks. The SC Board is a TNPA5349 (SC + Buffer Board Combo). The TV was brought to me with a SOLID (No Blinks) red light when the power was pressed. I decided to open up the TV and the SC Board (SN2) was short to ground 0.3 Olms with Fluke Meter. I replaced 3 out of the 6 of the MOSFET 30F131 which was short. All the other typical MOSFET was good such as DG302. After the replacement the SN2 now has 155K Olms. I plugged it in the TV shuts down after on for 1second. I can see the brightness during that 1 second. After shutting down, the TV flashes 6 times. Any tips?

      Panasonic P58V11B 8 and 12 blinks error "fix"
      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 here🤔?
      Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

      TV Model: Panasonic TC-P55ST50

      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

      Sony A1e 5-blinks help
      by jchon
      Hi I'm new to trying to repair TVs, but I saw a broken OLED offered for a reasonable price and thought I'd try my hand at it.

      I found the service manual, which was critical to know where to probe.
      https://www.manualslib.com/manual/20...1e-Series.html

      With it I was able to determine that my DKA board was bad, when P_ON#1/2 gets enabled REG_12 on the DKA board collapses. I'm assuming one of the downstream regulators has a short, but I couldn't work out which rail/component and replaced the DKA board entirely.

      Unfortunately the 5-blinks...

      Panasonic Viera Plasma TH-42PX75U 7 Blinks/8 Blinks/burned P board?
      by mmischni
      Greetings friends,

      I have a Panasonic TH-42PX75U manufactured in 2007. It has been trouble-free until recently. One evening I turned it on and it then powered back off and gave 7 blinks.

      First a question about the blinks. Everyone only speaks of a single number of blinks. I noticed on my TV, it blinks one fewer times for the first group of blinks, then blinks the full number repeatedly. So for my first code in question, the TV switches off, blinks 6, then blinks 7 repeatedly. When I disconnected the SC board, the TV switches off, blinks 7, then blinks 8 repeatedly....
