A couple weeks ago somebody spilled beer into my Denon avr-1400 and blew out several parts. I replaced 5 transistors and a resistor and everything seems to be fine now (all channels work and sound like they should) but after about 5 minutes of playing the protection circuit turns on. If I turn it off and then back on the protection kicks in a lot faster.
Any idea what is going wrong? My only clue is that something is drawing too much current, but does anybody know which parts to look at?
Thanks

If it take 5 minutes for the first time, but is much faster on the second time it looks to me like some temperature problem.
Maybe there is some temperature sensor and the idle current is too high after changing transistors. So the amp heats up. |

hi,
you have to recalibrate the idle current, also the output off-set voltage...after replacing the parts. these things needs to be checked..... |
