Hi all,

I found next to the dumpster an old Philips CD-350 player and since it
looked good, I took it home, in my mind just for parts. I didn't expect
a so old looking player to still work. Once home, the player had a
couple of obvious faults: motor belt broken and some led segment not
working on the display (that's strange, I've never seen led segment to
go completely off, but I think there's no other explanation since the
led digits are multiplexed and segments on other digits work just fine).
Another fault that took me a while to identify is that the player appear
to be able to read the TOC only once after power up. If I change the
disc it remember the first TOC it read after power up no matter what I
try. Other than that it sounds really good, I didn't remember I have
listened to such good CD sound previously (listened just to the
headphone output while it was on the bench, but still sounded kind of
great really). Does anyone have a clue about the TOC reading problem
anyway? Caddy's switches appear to work fine since the disc spins
momentarily after the caddy loads.

Just found the problem, three bad transistors (2 x BC338, 1 x BC328)
on the display/keyboard PCB. They probably
overheated and burned when the caddy movement belt broke.
Now the player loads and unloads fine and of course still plays
everything. Too bad the LED display is a custom one so
I have to live with broken segments.

Sorry for using google but my new provider doesn't have a nntp server
(any suggestion?)

Best regards
