Hello everyone.
Recently I've acquired a Philips CDV 496 video/audio player in a quite poor condition.
Initially, it did play CDs, however it made a weird ticking noise (probably coming from the tilt motor) and skipped randomly. It also wouldn't play VideoCD and just show SPECIAL on a black screen with a clock (I don't know if it can play VideoCD, though, and mine are "VideoCD 2.0" with a PC-readable track).
So I decided to give it a clean and used Videoclean spray on the head. While working out other cleaning on the inside I accidentally hit the alpha-adjust screw...oops
After that, without powering on the player, I went on and found a transparent CD disc. Then I inserted it and did the service manual's alpha/tilt-alignment procedure with the reflections method described there. I don't have a line-shaped light source, so I had to use my phone's screen placed on the clamper.
Powered it on but it will still take the disc and then tell me STOP. On some CDs it will try to play it but it won't do anything much than trying.
When I use the service mode, I get random errors on different discs.
Sometimes it gives me Focus OK, then Main Motor On and then it throws out the disc.
Sometimes it gets me up to TOC Ready with a Focus Error but refuses to do anything after.
Right now I tried yet another fresh CD and it would just keep ticking the head on the Start Position Reached state.
Before that most of the times the Error byte stated a Radial Servo Error. I'm not sure what a radial servo is, but I cleaned the motor that moves the pickup and all related parts including the zero-position switch to no avail and yet I get different errors still.
What else should I try?
If that's a bad perpendicularity issue (the head is not 90 degrees to the disc) which one might think from a weird clicking noise, maybe there is some other, better way of adjusting the mechanism?
I did align the disc to the clamper so it won't be jumping like crazy as well, and since then the clicking noise is quite less frequent.
Thanks in advance.
Upd: looking at some threads advising that with using the spray I might have blown more dust into the head, I tried getting it more Videoclean making sure the jet blows off everything inside as well. Still same Focus and Radial Servo error.
