| FIXITNOW2003:
Have you done the reset on page 47 ? to clear errors summery as bellow If the unit is automatically shut off after a DC error is detected, no key input will be accepted afterward.(The power will not be turned ON.)Simultaneously holding the [ADVANCED SURROUND] and [STANDBY/ON] keys on the front panel pressed for 2 seconds will cancel Key Input Inhibition mode after a DC error detection and turn the unit ON. |

I already took the whole thing apart |
| smk279:
I think it's too late for me to try that with the entire unit disassembled |
| smk279:
The transistor in the center of the photo is shorted and so is the brown metal oxide capacitor showing above it How do I change them do I have to bend all of the leads on all the transistors cause I'll be bending the board so I don't have to unscrew all of the transistors Is that the way to do it? |

No, that is not how you do it! Give it a proper clean up. It looks like the transistor leads are soldered at the board edge and you can desolder each lead of that transistor one lead at a time and bend them slightly away from the board. There appears to be an hole in the board for screwdriver access to remove the transistor from the heatsink. It is very unlikely that the ceramic capacitor is shorted. Probably it is across a junction of the shorted transistor. If you do have to remove the board, free all the transistor leads as above and leave them mounted on the heatsink. To be brutally frank, you have not yet instilled any confidence in me that you have sufficient competence to bring this attempted repair to a successful conclusion |
