Self check for no reason - always

See my comments above. The solution really works. barney6779

First thing I would do is unplug this unit for about 30 seconds and see if that clears up the problem. If it does then the microcontroller was probably just stuck in a loop and all confused. If you still have the problem after doing this, it will probably have to go to a professional repair shop or authorized panasonic service center for repair. I would guess that bad capacitor(s) in the power supply lines going to the logic section of the main PCB could cause the symptoms you're experiencing. Good Luck.

Hi, I took advice from this site and changed a 5 pin regulator chip on the Power supply board; STR-G6353. The chip cost £6.33 + £4.99pp +Vat from Nikko Electronics.

This unit cost me £500. I don't think I will be buying Panasonic again. Note, I also tried resoldering the joints before changing the chip. It made no difference. Seems the chip had genuinely blown. Possibly due to heat dissipation issue, suggest adding extra heat sink to stop issue reoccuring.

I fix 3 e95h using the str g6353.
