Re: EQ35 end of my rope...please help

Thanks to everyone for the help...I am working to pursue all your suggestions...
yes, both channels spike...interesting is that when Q1 and Q14 are pulled there is noise on the left channel...but not the right...and no spike...

I'll be back...damned if I am going to give up...there has to be an answer.

Well, I have tried everything I can imagine...the Onkyo EQ35 is connected between receiver preouts and and Onkyo amp...without eq function, the audio passes through as it should. But when eq is activated, the amp meters peg and the amp shuts down...

I have replaced all three ICs (Q201, 2 and 3) on the main board. I have replaced all the big caps on the main board. I have replaced the op amp (Q228) on the main board and I have replaced the two main op amps (Q1, Q14)on the eq board...I have replaced several transistors that were suspect. I have checked all the voltages on the main board...

Re: bad caps or something else?

Thanks for your suggestions. The board containing the caps also contains 9 output transistors mounted on a large heat sink. Apparently jiggling the caps also caused the solder connections on some of those Qs to open. I replaced 4 and resoldered them all...
everything works now...the Qs run hot and over time the solder fails? I guess the heat
from the hair dryer caused something to expand just enough to make temporary contact...
Thanks again

I have a yamaha receiver, rx v2092, that won't turn on. Kicks in the protection circuit and shuts down immediately...unless..

There is one board with four larger caps...two at one and and four at the other...if I heat the two caps at the front of the board with a hair dryer, the unit comes on when switched. However, if I only heat the four caps at the back of the board, the unit comes on then, too.

But...if I jiggle either group of caps...up front or in the rear...the unit shuts
down...

It's a hot board...with 8 transistors mounted on a big heatsink...don't...
