Question about Pioneer VSX-52TX Receiver
I have +45V. on emitter resistor R146 of Front Right channel !
all resistors..Q2-Q4, Q114-Q116 checks ok. I think is dc coming from
Q104, since voltages read different compare to Q103 I need to know what are Q103 and Q104 ? they are 6 legged (3 each side) small rectangular transistor,the marking on them: '1240' are they FET or Diff.Amp ? I need to know the part number, and where to order ? Any help will be greatly appreciated.. Thank You.
Voltages will read differently because the output voltage is wrong.
They are not FET and with all due respect, if you are not aware of what they are, you don't stand much chance of reading the service manual and affecting a repair.
Take it to an authorised Pioneer Repair Agent.

Possible solution: You set up your remote to run your amp from the TV control, using the AQUOS Link. Even though your amp is out of the loop, it's still recognized by the TV. You might have to reset the TV back to default and run the AQUOS Link again.

Unfortunatelly your receiver has failed. The front panel is telling you one of the power modules is probably bad. Not an DIY type of repair. These parts are near $40.00, plus cost of replacing.
Look at options to replace your trusted receiver with a new one.
