Cheers Andy, I took your advice and although it is not really for an old drunk's shakin hands I was able to get four lasers working. I owe you a drink!

Philips CD80 Flacky Problems
After the player is on for a few minutes if I change tracks or use the Random button I get the "ERROR" message. Have changed all of the electrolytics on the servo board and that made things a lot better but it is still a problem. Have also changed the bi-polar .68uf to poly at the same time that I upgraded the electrolytics on the servo boards. I have seen comments regarding grounding problems, but they were not specific as to which board or to specific components. Any recommendations would be appreciated.

Hi Gurus
Pardon me for my super newbe question.
I have made lots of upgrade to my CD67 like changing the caps, opamp, diodes and clock. Recently after I have bypass the HDAM, output caps and cut off the headphone output as discussed here, my display refuses to light up even though the buttons are working fine. I have checked the voltage output from regulator 79M18 and it measure 0.6v. I have also trace all the way to the transformer and it measures 0.6v as well. I have also tried to replace the display board and still not working. What could be wrong here.
I would also like to know how to measure the output voltage and impedence of the CDP correctly. I have tried to stick in the DMM to the cold and hot output of the RCA and it measures 0.06v and 0.32v for the L & R channel respectively with the CDP playing. The output impedence was measure at close to 50 ohm and 150 ohm for the L & R channel repectively. Why is there such a wide discrepancy on measurement and there is no impact on the centre soundstage?

hi cola,
read earlier on in this post i think one of the other guys had the same problem 99% sure its something that you have removed

Michael, I wonder if you could have a laser tracking problem or grease on the sled. Sometimes they will play ok if left to run, but cause error if you try random or track change. Just a thought!
I notice almost every company are using these stupid gold plated sockets now. What a shame it is only the earth, that has a huge contact area and not the 'live' pin that has a small contact area that is gold plated!

Hi I am the display light was on after the mod before I put back the casing. The earlier posts posted by the users is not similar to the problem i am having now as all the buttons are working.
Thanks
