Motor is not spinning. Sometimes it rotates in either direction, sometimes it rotates very fast.

@Lymmlad: You're very welcome - sorry it's only partial info - I hope it helps.

@Badrisuper: Don't worry, this has happened to me a bunch of times. I bet you've just lifted a pad on one of the caps you changed. Get your DMM in continuity check mode and test the tracks across those joints, particularly around the decoder chip.

If you find a lifted pad, you can usually just scratch a bit of the solder screen away from the broken track with a sharp point, exposing the copper, and re-solder it. Check everything conducts properly before putting the board in, and try not to flex it too much.

I did continuity check in most of places. I dont find continuity break. When I power on with CD inserted, motor is not spinning. You know when this happens?

Thanks
Badri

If you went from it spinning very fast in different directions to not at all, then my money is still on a hairline fracture somewhere. I'm only speaking from experience with my own player. Don't give up - it took me about 2 days to track my last one down. I was gearing up to find a replacement player when I finally got it. It may not be near anything you've touched either.

That's true, the board is quite fragile and it could be some nasty crack.

But you should also check the ribbon cable between the board and the mech. After many insertions the thing tends to make bad contact.

As you had the board out, in this case I'd say a fracture or break in the tracks somewhere.

You've not done something that most in the forum haven't done already!!!! ;-)

I have followed the discussion in this forum and made some mods to my CD63 with success. Thansk to all the good advices given here.
Now I have ordered 3 TX as suggested by Brent, i.e. 50VA 2X12V, 15VA 2X18V and 5VA 2X12V. But I am confussed by the way how they should be connect.
I believe for the 2X12V 5VA Tx, the first secondary is connected to U312 and U311 (0 V) while the other secondat is connected to U306 and U309 (0 V) (Brent has mentioned this somewhere in the forum).
Cound Brent or someone is kind enough to show me how the outputs of the other 2 TX be connected to the PCB by indicating which Uxxx I should connect to the secondaries? I don't want to burn out the circuits.

Hi Brent / Ben,
Further to my previous thread I believe for the 2X12V 5VA Tx, the first secondary is connected to U312 and U311 (0 V) while the other secondary is connected to U305 and U309 (0 V).

Please correct me if I am wrong on the following connections:
U305 - 12V in from 5VA Tx
U306 - 18V in from 15VA Tx
U307 - 18V in from 15VA Tx
U308 - 12V in from 50VA Tx
U309 - Ground for the 3 Tx
U310 - 12V in from 50VA Tx
U311 - 12V in from 5VA TX
U312 - 12V in after passing through the 16.4ohm resistor.

In the secondaries it has two groups of connections like this

:----- 12V
:
:----- 0V

:----- 12V
:
:----- 0V

Shall I connect the two wires with 0V together and connect it to ground ?

Thanks a million in advance.
