Re: Tnpa5081 af 7 blink error trying to repair
On EBay some suppliers have kits that include up to 31 components, but none of the kit suppliers show to contain the Q818.
Where can I get a kit for TNPA5081 with the Q818 transistor.???Comment

2sk3018 , KN is the smd code and they're tiny UMT3 package.
I've never found the right size, and usually end up the next size up which can fit.
It's one of those ones that may or may not fail. I just have a general rule to replace all that because it's caught me out and beats blowing everything up for the sake of 50 cents
I have also used 2N7002, just has a higher voltage rating and they've been fineComment

Pioneer Kuro Pro 111FD 8 blink red LED.
I have been trying to solve the power-down 8-blink red LED problem with my Pioneer.
So far I have replaced the power supply board, and the digital assembly board, I have reconnected the ribbons to all boards, ensuring the connections are good. Even though the problem is the 8 red light error and not the more common 8 blue light error code, I had Kcrownie,
based in North Carolina replace the chips that cause the 8 blue LED problem (the main board and audio board) the plasma is still powering... -

Years ago my tv gave a 7 blink code which turned into 8 during diagnosis. I had ordered a replacement ss board but somehow the tv started working again and i never used the board. Now a week ago my tv flickered and shut off at random and gave the 8 blink error code. The same issue it had all those years ago. The only difference this time is that over the last few months there has been some purple and green tinge that comes and goes in more solid colors such as white.
Anyway i checked all the screws and replaced the ss board with a known good one and still got 8 blinks. I saw a... -
For anyone interested just repaired this Sony Main board TV that had a 2 blink error code, the chassis is a RB2G which is common to quite a few different Sony models. The Ceramic 10uF 25V X7R 1206 capacitor C9114 was shorted which took the smd 2A 0603 fuse out F9101. This was powering the Buck converter TPS54332 which caused no 5V output from it.
See the attached picture of the locations of both components. I also attach the best service manual I found for this board for anyone else in a similar position of trying to repair this main board. It's not specific to the TV model however it gives...01-08-2024, 05:56 AM -
Hello Sharp TV experts
Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.
> I checked voltages on the power supply board and they all check out .. including 3.28 volts at the error pin.
> There is power to the cpu and T-CONN and no faults found there. The cpu has a flashing...01-24-2025, 11:51 PM
