I was wrong. I even remember reading on that magazine that the dots are denser at the insides of the cd.

Anyhow, this is now more clearer why first one or two tracks have reading problems on some players.
It just shows you always want to have the last word.

I have to explain what could be happening when the board is loose.
When a button is pressed, the board gets pushed and this pushes the board on to another button operating that function..
Rubbish!
Closest distance between button edges is 3mm (Small buttons) and 6mm (Big buttons).
All buttons are fixed by a rod and by the upper panel bores.
At least in this universe they can not interfere.
There is also nothing beneath the keyboard that could be touched and cause shorts.

You r so naive. That is not your problem at all.

I would like to remind you that you put this "problem" on the agenda, see reply #99...
The keyboard is simply too small to bend. Also no plastic bores to get worn out. All aluminium.

Please, I wrote that this problem is not a problen of any CDP-X5000 worldwide.
Nobody needs to open the player
- even though it is only 4 screws to be removed, but do not forget to have the transport mechanism centered,
or the platter will be in the way when lifting the upper case -
because of misinformation.

What sticks into my eye is the fact, that many transistors are part of the reset circuitry.
Transistors change value according to temperature, but not dramatically.
But still a path to examine?

Was anyone able to check EF-Balance and PLL Frequency?
(Page 10 on Service Manual) Did not have the time to do this yet...

Here is what I have modified so far. It remains to see how efficient this is. The transistor Q 601 has built in bias resistors, 4,7 kohm each. I have cut the track from D602 and taking the laser disable signal directly from pin 2,3 IC 602. This signal goes low after POR. I have removed JW600. Could not see the need for this one. I have taken JW602 and put it to ground instead of the input to Q601. I could not see the need for this connection. The lid switch is now on its own. And the laser has now got its own regulator. Hope is high again !! We will see.

Great! We will see! Still no skipping when being cold and still being fed by external clock?
All the best, Salar

Yes, still fed by ext. clock. I have had no skipping when cold but I have had problems with the start up of the player when cold. That is why I thought that your problem and mine might have one common solution.

O.k. Still one or two weeks left until spring.
It has becomre warm here but an unusual return of winter´s cold is expected for the weekend. But unluckily I will have no time to reproduce your modification...
All the best,
salar
