Trying to fix my Philips CDi 910

[amiman99]

I been having some problems with my Philips CDi 910. The front joystick input and Ir are not working.

I knew about the joystick problem for some time, but did not want to spend time in fixing it, and also I did not know about the Ir problem, because I did not have any remote controls for it.

 

So, I just received Remote control joystick form AA member, and found out that is not working. It got me thinking: Why both inputs are not working???

I used my old Sony camcorder with night vision to verify that the remote is working and it does, I can see the light coming from the remote.

 

It took me day or two to find service manual for the CDi. I found one for 220 not the 910 I have, but it's close.

Looking at the diagrams and schematics I came to conclusion that the "SLAVE" chip #7206 is bad (or some portion of it). Both inputs, Ir and front joystick, are connected to the chip.

 

I have on my unit rear joystick port and I verified that my joystick is working fine. According to the schematics the rear port is connected to the 68070 chip.

 

Does anyone have a broken CDi I could get the SLAVE chip from?
