Sony CDX-M8800

[B.I.G]

i need a service manual for a SONY CDX-M8800 .

the big flourescent screen died on me when i started the car something wrong with the car electrical system !

i fixed the screen (the transistor that was driving the smps for the vacuum tube died) but i touched two pins from the connector going from the faceplate to the main board , one of the pins is rated OPEN and the other -10V .

now the open button an the faceplate doesnt work and if i start the HU from the remote none of the buttons on the HU work only the remote buttons ! and if i start the HU from the faceplate the remote does not work ! only the OFF button then i have to push SOURCE and start it from the remote
