Morning all
After much scanning the net and messing with service mode, err 10 and 02, everything is pointing to a laser fault, Ray pointed to a weak laser for the poor sound and skipping faults i had previously.
The laser can be seen when no disc is in place but i have no idea if it looks weak or if you can actually tell by "looking"
I found an old thread where Poynton (Andy?) said to check v at R122/123 for +/- 5v looking at the schem is 123 supposed to be -?
I have +5.10 at both
I still have the transport from my
67 but previously tried to make it work in the 63 with no luck
Maybe swapping the lasers over could bring the player back to life?

Near to be fitted, I've to check it, remove the old reused Cerafines and drum rolls...
Even if it sounds bad it looks lovely!

Thanks guys,
Simon, is there any easy mistake to do there I should be aware of?
First I plan to get a try with wires from caps after 79/7812, a ground wire from each DOS to near RCA star ground and the RDxx lifted to steal their holes. That may works if the DOS is well wired...
Ray that's fine, with these ghetto boards I keep the player in the budget fixed before modding. It's a whole player under 150, maybe around 120€. That also sounds good

Just avoid brittle wires or making the wires too short so it's hard to finish the wiring job with it all in place. These sorts of boards can be fiddly because of having wires sticking out of both ends, but plan properly and take care and nothing can go wrong, well not much. Beware of keeping phase correct coming off the DAC.

I don't use it as it's not very useful. Just get better with the desoldering pump and use good tin-lead solder. The wick isn't normally required. If you can find one buy a silicone-tipped desoldering pump!
Tip: It's generally helpful to flow fresh solder onto a joint before sucking it away with the pump.

I don't use braid if I can help it. Those sockets should come off easy enough.
Fill all the gaps between the pins with solder. Then Quickly heat up all the solder by sliding the soldering iron up and down, at the same time gently pull the socket with pliers. It should pull out. Then use sucker to remove solder.

Same as Simon, add metal and use a pump.
This is how was fitted my DOS for the check-if-sound-or-smoke session.
Guess what? No smoke!

I can't tell much for home is full of familly life sounds: TV, kitchen and such... even before I put power on I first guess the speakers were humming but then realize that if not plugged it may be not the right time to listen
What I can say is that it works, the output level is lower wich is nice for me and, last but not least, it seems more "integrated", less like -good bass, nice mids and lovely treble- but so straight and real... remember I came from full factory output but the lost LM4562. I also feel the music to be slower... maybe low volume feeling in a noisy and crazy TV cartoons background!
And for the caps they are the cheap MKP 6.8 bypassed with FT-1 Teflon 0.022 and it's already nice!
