None of the pots seemed to be particularly off. I'm thinking I may have messed something up (ie maybe stripped something when removing the old capacitors). Is there anyone on these forums I can send the console to to have it repaired>

All the Capacitors seem to be fine too, but I ordered a multimeter to double check everything. Unless anyone has any other ideas I'll let you know what the multimeter saysQuote from: PigInTheMud on 02/11/2018, 10:25 AMI'm having the same problem too. I tried doing what Keith Courage above said, and removed one of the ground wires connecting from the laser to the motherboard and that didn't change anything. I also tried a very very slight pot adjustment to pots 102 and 104, but nothing changed so I set them back to their original positionsIt's possible the caps you replaced in the cd section of the pcb are not soldered in correctly, however I'd say it's also more likely that you just need to adjust the pots now that you have new capacitors installed. There's a guide on here how to do it by ear and it's very easy to follow.
I recently picked up a PC Engine Duo that worked for the most part. Had quiet sound and some issues reading some discs so I decided to do a full cap replacement.
After the full cap replacement the sound is much louder and the visuals are clearer. However now when I turn the system on it says press run to start, but when I press run it just loads and the disc never starts spinning. I took the shell off the see if anything was getting stuck. I have determined the motor is in fact working as the laser resets the position to neutral every time I turn on the system. The laser is also obviously getting power since there is a slight red light noticeable inside of it and 2 times I saw it twitch up and down for a second as if it is trying to focus. This twitching doesn't happen very often though. The laser also twitches everytime I power up or down the console
Is it possible that I burned the laser out when replacing the capacitors? Could one of the capacitors that I put in cause this if they have a bad connection? I don't have a voltmeter so I haven't be able to verify that every connection is 100% but everything seems to be pretty well soldered in and connection.
There's a chance I removed the wrong ground wire though. Can anyone provide an image of the correct wire?

Quote from: SignOfZeta on 09/04/2010, 11:06 PMOh yeah, I forgot about it. I'm afraid I might break it like all the other kids in the physics labs. My college didn't have anymore by the end of last semester. I also don't really know how to use it. What am I checking for... voltage? Amperage?Quote from: PigInTheMud on 09/04/2010, 02:27 PMWell, I ordered 2 more from mouser to test if was actually the wires at fault, or if it was the switch.Don't you have a meter?

I just like having original items.Quote from: PigInTheMud on 09/02/2010, 08:32 PMAm I going to have to buy that overpriced $45 one from ebay?Why in hell would you pay $45 for a decades old used AC adapter when you can get one from RadioShack for $30 (actually only $20.89 as shown in rag's post, with a free plug and free shipping).

Quote from: SignOfZeta on 07/29/2010, 05:22 PMYou got you power and ground from the HuCard socket?I never thought of connecting the ground and 5volt anywhere else. Where did you connect yours?
Hm...I'm not sure if that is the cause of you problem, but I didn't do that with mine.
