SOURCE: won't record
I've just spoken to a friend who also has one of these older Philips recorders & he has the same problem.
As per my previous post, he fixed his problem by locating old stocks of blanks. New audio discs seem to have been manufactured & optimised for fast writing speeds (up to 32x speed) & this is causing the problem (you can't write at x1 or x2 speed to these new speedy discs).
Trying a few different brands of discs to try out is a whole lot cheaper than a repair. I suggest when you find a brand that works, you stock up on these discs as it seems they will become ever rarer.
Good luck!

SOURCE: CD player skips on early tracks
The lens assembly in a CD player glides along on a two rail track, kinda like a railroad track except tubular. The lens carriage is moved over this track by a small motor driving a worm gear. (Think long, tubular and spiral). If the rail tracks or the worm gear dry up or have dust accumulating on them, this could be the cause. Normally they have a light gear oil or lithium grease on them to keep them lubricated.

SOURCE: NAD C541i CD Player plays but...
hi, i've had a few nad C541i's and not so long since the sound on one of them cut out for milliseconds and on some occasions the sound would make the noise very much like a severely scratched vinyl record, i thought it was a faulty laser so i tried another KSS-213C laser out of a scrap kenwood and the fault persisted. to cut a long story short, i took the main PCB out and there were various dry joints. once these were resoldered i was blessed with a fully functioning player. hope this helps?

SOURCE: CD player WILL NOT PLAY and does not recognize CD presence
HI. this is optical lens assembly failuer. the optical lens is burned out, in return, inducing the (no CD) message. simply replacing the optical lens assembly will fix this issue.

Hello guys,
I have a Technics SL-CH770 connected to ST-CH770, and then the amplifier from the latter SE-CH770.
Now, my question is, when I power on the system it shows U70 error. CD display shows track number and the time counter goes well.
The only problem I have is there is no audio when in CD mode, but for tuner (am/fm) it gives the sound output.
Any help would be much appreciated.
Thanks,
Z
