Hi. Yesterday receiver ''stuck/freeze'' on ''POWER ON''. Today no display, no blink, only main relay click. All compination enter+power button etc.... doesmt work.
Amp section is perfect.
On IC581 all correct ( i have input 5V/OUTPUT 3.3V)
On D582 /cathode/ i have 2.7v
C333/C506/C552/C606 are good, correct voltages.
I don't have osciloscope to check crystals on processor. May be receiver won't boot firmware...
Can you tell me how continou.
Service manual is too big (32mb) to upload here, here is a link
