Wouldn't turn on so I checked the ac side and found a bad solder joint at the main transformer. Now it turns on for a short time then displays "Power Off" I found an amp tansistor bad and replaced it (Q3) a 4.7 ohm resistor (R365) and transistor (Q303) Replace the bad parts and still says "Power Off" after a few seconds. Tested electrolytics and didn't find any bad. Anyone have any ideas I Need Help!!!!!
Schematic at the link below.
I decided to replace all the power amp transistors so Q1, Q2, Q3, & Q4 have been replaced, still goes to "Power Off"
