Denon DN-961FA - reading problems

redrabbit · 14th March 2008, 05:23 PM

This older broadcast type player has trouble reading 75% of my discs.
It will either initially read the disc, or it will fail/error.

What adjustments can I preform ?

Understand that I am not too familiar with the insides of CD players, but I have an analog scope + other test gear....and my friend has some CD alignment discs.

He also may have some info on the location of the alignment pots...maybe not though.

Thanks,

Alright, so this seems to be a common problem/question, here in this forum.

I wonder why no "sticky" , for common troubleshooting and maintenance of optical reading players ?

Here is a troubleshooting link, with thorough descriptions:

Opened it up, cleaned the purple glass eye w/isopropyl 99%.
Seems to play more CD's, but it spins up 2 or 3 times to read.

Laser assembly is a KSS-240a. Three trim pots on it.

Hello,

On the right side of the unit's chassis (from front) there are two trim pots for focus and another setting I forgot. Twiddle those two pots carefully for best reading results.

I once owned 7 of these funky little players.
