Already now, I would like to know what it also means LOPTR and LOPTX.|
Thank you for your constructive guessings. I have already started to dismount the receiver and found out, with the help of my multimeter and the datasheet, that one of the two final stages is blown. I suppose, |

|14-06-2008||I checked all semiconductors and the emitter-resistor, I´m pretty sure that the final stage IC is the only part I have to change.
The only thing I am wondering about is, that the receiver even shuts down if the defective amp IC is soldered out. I d|

|15-06-2008||Hmm...exactly what is the IC? I was not aware Yamaha has started using Ic's for outputs! I'm used to seeing discrete outputs & thought that you were able to find a defective output transistor which is rather easy to spot w/ a meter. If infact an Ic,|

|15-06-2008||My problem is, that my english is not that good, to be sure, that I´m saying everything correct.
The defective part is an stk402-120, and I think this is an IC, an integrated curcuit. I thought this is meaning the same as discrete amp.

Please i have 3 car's with same ecu,

|15-06-2008||Ok, I see . Nothing wrong with your english... & yes the STk is infact an IC which yamaha is apparently started using.
But I am willing to bet that you are looking at rear channels ONLY. The STK in question is only a 2 channel audio amp while that su|

|15-06-2008||There are two STk402-120. I guess one for the front channels and one for the rear. There is a STK404-120 also, I guess this one is for the center speaker, because it s an single-channel amp.
