first of all, congratulation for your website.
My panasonic 42" with TNPA5390 and TPA5330, was resume from 7 blink led after replacing these components:
POWER SUPPLY TNPA5390
After these change I got 6 LED blinking. After replace the
The TV was ON for a few hours now again 7 blinking LED.
This time, NO previous components are in fault.
I noticed that on SN2 connector I do not have Hight voltage and Q300, Q301, F102 are OK. I have checked also the 5V (C561) and 15V (on TP82) near the connector SN20 and I read both.
What you suggest ? Thanks and regards
You have already gone way beyond what most people would try in order to get that item working. The next step is to get a FLIR camera and see what areas are getting hot and a magnification device to inspect all the SMT devices on the board.
