|
|
I have a pioneer sx227 receiver with a defect in the power amplifier.
The two power transistors (C3180 and A1263) had a short circuit and I replaced them.
After replacing them i noticed that they still get very hot. There is a current running through them although nothing is connected. The left channel has no problems.
Probably something else is defect. Anyone got a clue? |

Have you checked the rest of the parts, especially semiconductors and resistors, in the defective channel? |
