GadgetUK164 - Retro Gaming Repairs & Mods Me either, until I ended up with one. I was kinda hoping for a bad gear since and knowing that my gear was fine just added a lot of uncertainty about what was actually wrong with mine. Because no CD-ROM² adjustment guide existed and no one was confirming that it was close enough to follow a Super CD-ROM² adjustment guide, I opted to swap in a known-good laser from a working Sony Discman first. Got mine from a D180K Car Discman. Because it didn’t do the trick I moved on to the pots and got it working well. The old laser is presumably a good spare. Older CD-ROM² units have a KSS-162A laser assembly and the two are completely interchangeable. A lot of old Sony devices use those, including some Sony-produced models sold under other brands ( Radio Shack “Realistic,” for example).

Yep, I have one of these that I repaired, there were no teeth missing from the center gear but it was very yellowed and the motor wasn't running. I removed the center gear and the motor ran fine so I replaced the center gear with a new one and it works perfectly. I also recapped the board while I had it apart since I had already ordered in a cap kit with the replacement gear. The only tiny issue is that the replacement gear is a bit noisy, the teeth must not be exactly like the original.

Banging job, looks beautiful! I too did an IFU-30 optical drive repair about ~3-4 years ago. Ordered one from Japan that got damaged during broken, all kinds of plastic pieces from gears came out in about 4-5 pieces. Wasn’t the classic middle gear issue, but I contacted an ebay seller in China who was selling a middle gear and asked if he happened to have a part that looked like the one I found on the forums when I pieced the broken pieces together. The whole thing was this epic quest to figure out how to repair a 30+ year old drive, I was so happy when I got it working again.

Today an IFU-30 together with a CDR-30 came all the way from Japan to my door. Thanks to Your video,I was daring enough to buy an "untested" unit for pretty cheap. The middle gear was yellowed, like to be expected, and so brittle, it fell apart as i touched it. Replacing the gear wasn't too hard. I lobed everything up with silicon grease and... nothing *lol* So the poking around began, fearing that it might be a dad laser unit. Though i noticed that the laser didn't move to it's start position. "Is the motor dead?" So I connected it to an external source. Nothing again, then it moved a tiny bit, and nothing. After a few more jumpstarts, the motor started to move the laserunit more and more reliable, in the oposite direction with switched polarity too. So it was just a "dirty" motor that wasn't used to moving anymore. Yay! i have a working PC-Engine CD-unit! Thank You ^_^

Dug out my Cdrom2 setup out of storage quite a few years ago and had the non-spinning disc fault. The set-up had been purchased new in 1990 and not used after I moved to a Duo-R previous to the diagnosed middle gear issue, so the gear is still going to go bad without use. Purchased a couple of replacements from a seller on ebay (didn't realize the washers were so small, I thought the seller had sent me an empty bag) and finally decided to have a go at resurrecting the old CDRom2 unit. Watched this 'tutorial' video twice and after digging out all the stuff, well, .....it's fiddly. You missed out the best bits, trying to remove/attach the small washer and removing/attaching the upper lid magnet. *ucking magnets.....ended up removing the 2 screws on the lid hinge to lay it down flatter to get better access. Everything now seems to work OK and I'm quite pleased considering that for 30 year old tech the only fault that developed was a piece of plastic the size of my little finger nail. Pity that it's going back into the box, replaced by the SSDS3.

Thanks! You have a few options - if you are looking for a CD system, consider getting just a standard PC Engine (or Core Grafx), and get the Super SD System 3. That way you can play all games from SD card, dont need any "System Cards" or hucards either. If you want actual CD hardware and dont want to use SD cards etc, you should look at the Duo RX - but they are the more expensive. A step down from that cost wise is probably the Super CD-ROM2, but those are between £150 to £250 still (more than a Super SD System 3). Then finally the cheapest options is probably the Duo, but they typically need recapping. And then theres the IFU and CD-ROM2 like I showed in this video. Cheapest most powerful option imo is basic PCE with a Super SD System 3 - you can still collect actual hucards for that setup, but not CD's as you just stick the ISOs on an SD card. I cannot do repairs and mods for people as I have a full time job and long term health issues =/

The US models sometimes need recapping - so maybe check the capacitors. It could be the IC that drives the focus coils, or bad focus coils on the laser assembly. If you can work out where they are connected you could measure those coils or even test them by driving them with a signal generator (low voltage, like 1v p2p or something). If you have a working unit, try swapping the laser over to rule out problems with the coils or laser.

Today I got an advertised working CD-ROM2 unit from Japan and the laser doesn’t move at all and the CD doesn’t spin either. When I opened it up, the gears were fine, but a flat plastic piece came off upon opening up the case and it looked like it belonged to the laser assembly because the laser moves very loosely with my fingers. Turning the gears doesn’t move the laser at all. Do I have to get another laser assembly at this point? I’m sure the laser is fine, but that plastic piece was needed to have it operational.

Ah, the quality of the electrolytic capacitors used on those units vary so wildly between units, the US black CD roms typically are leaking on every unit I've opened so far.

Judging from your wrist band, I'm guessing you got the cold from Blackpool Chris. Hope it wasn't me to pass it on to you. I never would have guessed that cog to be the problem. I never would have guessed you can actually buy a single one of those tiny cogs from hong kong. Amazing! I'm guessing the yellowed cog was slipping on the rod. Something like that. I've got an unrelated question Chris. I'm troubleshooting an original xbox. It's got a faulty power supply. I've taken it out and measured the output but it's not giving any correct voltages. According to the pinout it's supposed to give 12, 5 and 3.3Volts. The big cap on the input side is charging up to about 300Volts so I'm guessing that's alright. The board looks fine by looking at it. Do you have any experience working on these power supplies?

@GadgetUK164

6 жыл бұрын

Yeah, I think I picked up at Play - lots of people had been recently ill, so don't blame yourself =D Yeah, you can but those cogs from that place in hong kong, or console5 in the US! Sometimes they appear on eBay too! The cog had expanded and was jamming the motor! That's why the driver chip was getting hot and also why the unit was silent. If the cog had slipped I would have been able to hear some sound. Regards the XBOX PSU, if the fuse isn't blowing and the cap is holding 300 volts, that shows the switching transistor isn't shorted. It could have a fault on the transistor though, maybe its not switching. The first thing to do is inspect around carefully looking for any burned out or suspicious looking components. For example, you could have a bad electrolytic, or a burned resistor - maybe an open circuit resistor that looks OK but is open circuit. Something could have gone wrong on the secondary side (where the lower voltages are provided), and if one of those voltages is wrong it will disable the main switching transistor via an opto coupler I think. So the opto could be faulty (little chip looking device with 4 pins, 2 on each side). Other common faults on those are zener diodes failing (components marked with Z prefix). There's no easy answer really other than checking the components you can check and hope there's an obvious clue with a burned component.

What I would do is look for one at a carboot sale - they sell for like £5, mega cheap. Then just swap the PSU over! Some of the PSUs are better designed than others depending on the revision.

Good stuff! I was the one that asked about the potentiometers on another video. I was able to solve the issue with your recommendations, thanks! Here's the thread I started about it over at PCEngineFX www.pcenginefx.com/forums/index.php?topic=22853.0

Thanks! That's great =D Will check out the link!

I have one of these units which works fine for the moment, but I know I should replace that damn gear at some point. Not looking forward to it because it's a fiddly job with my sausage fingers. Where did you get that grease ? BTW, next time in Blackpool, join us for dinner. sorry, tea !

LOL @ sausage fingers :o) It is fiddly replacing that split washer even with my ninja fingers =D I would prefer sausage fingers tbh - that's something I dislike about myself. Went on a date when I was younger and the girl liked me up until she noticed I had ninja fingers =/ and then said, wow - you've got small hands, my fingers are bigger than yours. Things went down hill from there! Sausage fingers for the win!!!! You can buy molecote grease on eBay! And next time at Play, yes - I will go for dinner =D

My word that type of plastic is annoying (I'm not complaining about your vid, can't be helped). The wife buys crafting supplies from various places and a lot of the stuff comes wrapped in that god awful noisy stuff, drives me up the wall. Is it cellophane? I can't remember if it is that or not.

Yeah, had I known it was going to create that much noise for the Mic I would have removed that plastic before filming! It won't happen again lol! =D

Is that the disc that came with Madonna's book? Because that's the best version. The book fell apart though.

LOL =D Yeah, I felt like putting it away when I first saw how it was behaving! Sometimes you just have to persevere until you've done everything you can think of =D Grateful to Dennis for sending it to me - it's such a good example of a PCE CD-ROM2.

I've posted a comment on there - I think it might be a bad laser. You should check the caps on that too - some of them do suffer bad caps (even though not SMD type).

@@GadgetUK164 Thanks for looking - is it possible the laser is bad even if I can see the laser lighting up? (when I trick the unit into thinking the cover is closed)

It's possible that the laser is weak (despite being visible), or there could be a focus or tracking problem with it. You would take the laser unit off and submerge it in IPA for a few hours, then dry it off - shake it, leave it for a bit - heat with a hair drier to dry off any internal IPA, then clean the lense and re-fit it. Sometimes that can work! Beyond that, it could be something wrong with one of the BTL / H-Bridge driver chips on there maybe. Or even something wrong with the RF amp.
