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 hereπ€?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting π.

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 question - I have replaced the PSU on my own iMac Pro. However, when removing the motherboard I knocked of a 120 OHM 30% 0.3A small surface mount common mode inductor/filter (~0602 size) in the ethernet circuit near the female RJ45 port.
The closest match I can find on Mouser is 120 OHM common mode inductor at 100MHz - my question is this frequency correct for a motherboard? The schematic for the motherboard only provides '120 OHM 30% 0.3A' and the TDK part number does not return anything in google.
Sorry, I am not experienced hence a basic question.

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.

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.

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....
