RB4 intermittant failure.
 

Gents. I have a stock RB4 unit with 10CD unit.Grand Cherokee 2004.

lately the unit start to fail by tuning off and only the red LED is flashing. It seems to be heat related, it works again when car is turned off and unit cools down. I assume a deffect capasitor or som other electronic compnent. Anyone who has same isues? Anyone who has the electronic diagram of the RB4 radio?
