Hello,

I have a DEH-P4600MP that I installed a IP Bus Ipod adapter (ip bus to 3.5
mini plug) on and it worked ok for a while.

I think my iphone may have put to hot of a signal in the input of the E-Vol
chip PML003.

The unit will play all channels when it is first turned on, but after about
2-3 minutes the left side (front and rear) start to distort and then fades
off.

I have it apart and the E-Vol smt starts to get warm and then hot after
about 2-3 mins. After it gets real hot the left side goes out.

I have cooled it down with compressed air (can upside down) and the left
side will start working again. Right side works all the time.


There are a few caps around this chip and I was thinking it was a bad cap,
but a bap cap(s) shouldn't make the chip get hot. I don't guess.
I also used a ESR meter on the caps and they show the same values as the
another unit I have. (4.7uf and 1uf at 50v)

This is a SMT chip and I have another one on a spare unit.

Any way... Does anyone have any ideas on this? I think it is a bad chip, but
would like another opinion. Plus, I don't have a lot of experience removing
and installing SMT chips.
I do have a PDF of the service manual.
TIA!
