Grundig XEPHIA 42 PW no image
Grundig XEPHIA 42 PW 110-6605 chassis P7
PSU TNPA3570
Sub power R84-194R-5
YSUS Board TNPA3543
SS Board TNPA3544
Main R82.190R-3
Old plasma tv no image
Standby led is turning to blue from red if i press a ke(menu) from front panel but no image
IN PSU TNPA3570 There is 0volts in main cap C466 so no Vsus in connector P2
The only voltage in all connecters is 14V in PIN 4 connecter P12
Main cap 0v
D404 coming 220v out 194V may be strange
D403 no incoming voltage... -
