Hi

Recently I brought an old Toyota, and needed a CD player, cheap...
eBay provide a CD with its separate master radio/casstte unit, the CD
was sold as not reading discs. Toyota compact Disc deck 34203

Firstly, thanks for the great CD FAQ:
http://www.repairfaq.org/sam/cdfaq.htm

This page was also invaluable for wiring up the radio/cassette unit to
my bench PSU and a couple of old 4 OHM PC speakers.
http://www.carstereohelp.net/wireharness_Toyota3.htm

I tested the unit, it loaded a disc but the display showed no track or
disc info. the player spun up the disc, tried to focus a few times
then ejected the disc and shut down.

So I opened it up, I cleaned the optics, feed in roller etc;
reassmbled the top of the player and tried again, no change.

I removed the main PCB from the underside, it looked clean. I tested a
few components around where the feed from the laser pickup came in,
all ok. I reattached it and 'scoped it but couldn't see much happening
and wasn't sure what should be where.

I was begining to think the laser pickup assembly may be defective.

Then on the main PCB, I noticed a 100uF 10v 85 degree Electroyltic
capacitor,( its body was dark teal and it was made by ELNA), situated
in front of where the Flexible flat cable from the laser pickup
connected to the PCB.
It appeared to be slightly buldging underneth.
I unsoldered it and a leg fell out of it!
Where it had been there was nasty black electrolyte! I cleaned up the
PCB with 91% isopropyl alcohol on a cotton bud/Q-tip.
As I am not working in electronics for a living anymore I didn't have
a new replacement capacitor. An old Compaq motherboard kindly doanated
a 100uF 16v 105 degree capacitor which was taller than the original.
I mount it at an angle, facing the connector, to avoid it hitting the
mechanism, on reassembly, (Note: a circle around the positive pin hole
denotes polarity on this PCB). I reassembled the unit inserted a CD,
it recognized it straight away and played it all without a problem!

Hope this helps someone in the future.

Best regards,

Robin

I love getting something for nothing...relatively speaking, anyway. A
new unit of that quality would have cost perhaps hundreds of bucks. I
really enjoy being able to have stuff I normally couldn't (or wouldn't)
afford to buy.

All kinds of gadgets surround me right now. Most of them didn't work
when I got them, or else I built them from scratch...or they failed
sometime while I had them and got fixed in-house.

I rarely ever buy anthing retail, and I hardly ever get rid of
something, unless it's to get a better one of the same.

Well, good for you then. After all that work, you ended up with a stereo
that still sounds like ****.

I always thought Toyota factory fit stuff sounded good.

Anyway, if it were **** it would be cheap, easy to fit and looks
original, **** g

plus, it wasn't work, it was fun.
