Hello, I get this radio for repair, but without car (far from me). Someone tried to repair it before
and many capacitors are unreadable due to PWB cleaning. First I need to identify them. Can anybody
make hi-res photo of main board from few angles ?

Next I have few questions, because service manual seems to be not available.

There are ILL and DIMMER on the main connector. I found, that on ILL there is 12V in every
state (radio ON or OFF). And it is probably output - not input. Why ? For what ?

Backlight for buttons light only when DIMMER is connected to some voltage (6V-12V) - it is OK ?

Lamp for LCD = 9V/35mA ?

Lamp for buttons = 6V/35mA ?

Yellow capacitors - are they polarized ? I´m not shure.

Thank you for any help or advice.

Hello someguywithajag,

thank you for your attention and your time . Please can you help me find out what
capacitance and voltage is printed on some capacitors ?

Yellow: E817, E2002, E285, E301
Black: E2009, C814, C286, C290, C287, C289, C284, C283

Thank you very much.

Sorry for the late reply! These are the values:

Yellow:
E817: 3.3μF
E2002 there is no yellow at E2002. I see a blue one with 2.2μF
E285: is this the green one? if so that is 7μF...the yellow one at E225 is 2.2μF
E301: there is no yellow one here. There is a brown one with 0.1μF

Black:
E2009: 1μF
C814: 3.3μF
C286: 2.2μF
C290: 2.2μF
C287: 2.2μF
C289: 2.2μF
C284: 1μF
C283: 1μF

Good luck!

 

Thank you very much for the values sent. I'm working on it in my free time, but it's going slowly.
Almost all of the C's are leaked and have no capacity. Hopefully I can save them.

 

you’re welcome… Sounds like a tedious job…good luck!
