Post subject: Pioneer CLD-2090 will not see digital audio on LD Posted: 09 Mar 2016, 08:10 |
|
i just bought my first somewhat decent player, a Pioneer CLD-2090 and i'm baffled by some of the issues i'm encountering. the player was purchased on ebay, shipped a very short distance (maybe 30 miles in all?) and had the transit screw in place and right out of the box, digital audio tracks were distorted and stuttering. some research online told me that the problem could be fixed by adjusting the RF pot inside, which i did. unfortunately, i also felt the compelling need to mess with the tilt balance (there were some issues getting the RF set correctly) but moved it back EXACTLY where it was when it seemed like it wasn't doing any good or worse. with enough adjustment to the RF, the audio cleared up and then i realized the player wouldn't switch to digital tracks anymore. even setting everything back to how it was out of box, i'm still getting no digital audio. what could be the cause of this? not sure if this is worth mentioning, but CDs play fine, video is great and analog audio is working perfectly. it just WILL NOT switch to a digital track and obviously isn't reading the audio data on the disc.

Are you sure the LD you're testing with has digital audio? 3. Which audio connection are you using (RCA or optical)? 1 & 2. yes. the test disc i'm using ( http://www.lddb.com/laserdisc/08863/9-3 ... orse:-Weld) has both audio tracks and was playing the digital track when i first hooked up the machine, just stuttering badly with a layer of distortion over it. analog played fine. now it wont see a digital track on the disc at all (analog still plays fine). 3. RCA substance wrote: The distortion on the digital tracks might have been due to laserrot. Sometimes it only affects the pcm tracks but the video and analog are fine. that would make sense, but i didn't see any signs of rot and it wouldn't explain why the digital tracks DID play back at first and then no longer exist after my admittedly ill advised tinkering. strangely, i put it another disc last night that came with the player (Speed, specifically. ugh) and it read the digital track on the disc with garbled, distorted output. this is so far the only disc i can get a digital track to even appear on.

Did you adjust the RF slowly little by little to get where you're at? Did you try turning both directions from where you started to see if one way improves and one makes it worse? extremely slowly, both directions. at this point, the analog audio just gets worse going too far either way. digital audio doesn't start reading again adjusting in either direction.
