Problems with Kenwood KRC759R

[Old Sparky]

To explain; About a month ago I was asked if I could repair one of the above car radios in which the controls had no effect. Suspecting a faulty FPC (ribbon) between the motorised front panel and the main PCB, I ordered a replacement. For various reasons I didn't get around to the job until yesterday, the radio being left in a dismantled state meanwhile. I fitted, with some difficulty, the new FPC only to find no operation at all, on top of which when I powered the motor seperately to open the front, I found that the front panel/display unit to be upside down. THis must be due to the fact that I have fitted the FPC incorrectly (I know I should have taken photos, but didn't expect the radio to be left a month or more in a dismantled state!)
I've ordered a manual from an on-line supplier, but, in the meantime, does anyone know how to reassemble these things correctly?

(7.30PM) Since writing the above I;ve worked out how the FPC connects between the display and main PCB, though I still have to fit the brackets with the rollers through which the FPC passes. However I still have no sound and no display or controls operational, and am still awaiting delivery/download of the service manual. I have replaced these FPCs in the past, but not for a long time so I'm obviously getting something wrong!

I've now received & downloaded the Service Manual, but it doesn't appear to include any instructions or diagram showing exactly how the FPC is fitted, so it looks as if I'll have to work it out, and also check if there is any other fault present. At least i now have circuit diagrams, which may be of some help! Since writing the foregoing I have found that i had inserted the FPC upside down, so no contact was being made between the front panel & the main PCB. That having been sorted, I'm now trying to work out how the FPC is routed through the rollers to allow the front to fully open & close. It looks simple but it ain't!! The moral of course is, make notes, or better still take pictures before dismantling. My only defence is that I didn't expect a 6 week delay between taking this on and finishing the job!!!

All now sorted, having finally sussed out how the FPC is routed through and around two rollers in the front of the stereo, and how a bracket, held in place by 4 tiny screws which I kept dropping!, was fitted (under the FPC, not, as I at first thought, because of the shape of said bracket, over it! An irritating job, to say the least, but if I'm asked to do another of these, I'll know how!!!
