my loved Pioneer Plasma 5090H doesn't work anymore :-(.
I hope, that you can unterstand my bad english.
I have this symptom:
When i start the Pioneer, the blue LED blinks 7 times first. After 3 seconds, the blue LED blinks 8 times until i switch the power button.
I tried to solve the problem with the replacement of IC 7951 (new NJM2846DL3-18) on the IO_Audio_Assy (AWW1354). --> no success
After that i checked IC7901 (NJM2846DL3-05) and IC7911 (P0200WNA1ZPH) and they work fine.
My last check was IC 4404 on the AWV2556 (Main Assy) and this regulator works fine, too.
--> no success
I read something about an new capacitor to help IC7901 but, i don't know, which capacitor i have to renew.
In another thread i read something about the Main Assy, but i don't know the part, which i have to renew. :-(
Now i have no further ideas.
I would be very thankful for help.
