HOWDY, NOW YOU COULD TRY THIS ONE: POWER THE RECEIVER UP , THEN PUSH&HOLD !THE VIDEO 1 BUTTON, THEN TURN THE PIECE IN THE OFF (STANDBY MODE ) ,IT WILL SAY "CLEAR SO IT SHOULD BE BACK TO IT,S ORIGINAL FACTORY SPECIFICATION,S. SUCCES ! AMSTERDAMCOWBOY-HOLLAND-NOW FLORIDA! 4-EVER

SOURCE: amp blows fuses
The fuses are there to protect the internals of the AMP.....
Please check that the correct fuses are installed......
if the incorrect ones are installed then a fire may develope...
There should be a manufacturers lable on the external chassis that details the fuses to use....
Fuses now days can be slow blow or fast blow....so the correct fuses must be used.....dont increase the fuse rating past the chassis panel label...but make sure they are correct...if they are correct then the amp needs a service to determine where the peak loadings to the power supply are originating from...
Some one may have installed incorrect fuses in the past...
Cheers from YUBEUT

What are the part numbers on the transistors you replaced?
Did you replace transistors in the output section and the power supply section?
Does this amp have the defaced ICs labeled B52 and F16?

The transistors you need are 2SD2560 and 2SB1647. (either you miss-read the D for a B or it was a typo) You can get them at: www.mcmelectronic.com
2S is a prefix on all Japanese transistors.
The 010 is a date code
Also check for open resistors from the base of those transistors and the dual emitter resistor (large white three leg resistor .22ohm)

Though any transistor(s) might well have gone and the capacitor could be changed, I see no reason to change any resistor unless it's burnt up or giving an incorrect resistance reading. A multi-meter will tell you if a resistor is working or not, if it's not dead or weak it won't make a lot of difference to the circuit, but replacing it will simply cost you more money!
