My PC-FX is finally starting to derp out.
The CD loads poorly.
Some games (real CDs) get skippy audio.
Zeroigar will often just choke and die.
I recall mention of a fairly easy adjustment to get the thing working again.
I'm guessing SamIAm will have the answer, because I think he was the one doing said repair.
I NEED TO BE ABLE TO PLAY YUNA AGAIN. HAELP

Open her up, find the row of three white potentiometers, and adjust the middle one in 1/8 counter-clockwise rotation increments until it works. A single 1/8 adjustment might do the trick; if it doesn't work after four 1/8 turns (aka half a full rotation), it's probably not going to work, and even if it does, you'll probably burn the laser out pretty quickly. You can hear it give off a weird high-pitched squeal after a certain point.
You don't have to dig far, by the way. Once you get the outer case off, you'll see what I'm talking about. Good luck!
EDIT: Given the number of times I've seen this fix be effective, I really think it would be a good thing to sticky. If a mod (Necromancer?) will give me permission, I'll make a custom thread.

Heck yeah, that'd be great!

Sweet. I'll give this a go in like a month when I get back from Japan, lol.
Gonna keep my eyes peeled for non overpriced FX games.
I'm sure that will go well.

Just a good ol' pot adjustment? Saving CD consoles since forever eh.
Is there such thing as a replacement laser for a PC-FX? I'd assume something like that will be necessary eventually, no?

Ill do this when i get back from Japan.
I figured it was easy, but didnt know the things to touch.
Seems alot like fixing a 1541 drive

This fix works, confirmed! And it should be a sticky topic if it isn't already.
(No, Necro it wasn't the unit you sent me, that works fine :D )
Safe travels back to the US, Ark.

Did this pot adjustments and other fixes custom thread ever get stickied?

I don't think so, most of the content talking about it is in this thread from Sam's paragraph and the first page of this thread: http://www.pcenginefx.com/forums/index.php?topic=19329.0

Sorry guys. I actually wrote up a draft of all the text for a guide, but I really need to get a nice set of pictures, and there are other things taking priority these days.

Heyo Sam,
No worries. Just curious as I think I need to adjust some pots on my FX now too. ;)

This is a great question, does anyone know? I usually like go grab up a spare laser or two for my systems to keep in reserve.

HOP-E1 is the one to get.
I bought six cheap Chinese knock-offs (~$2 apiece), and only one of them worked.
I suspect that many of the more expensive listings you'll find are actually just people buying a bulk-load of these knock-offs, then filtering out the ones that work. That's not necessarily a bad solution, though. If you want to find an authentic product, you'll have to search for a while and pay accordingly.

Picked up a spare PC-FX HOP-E1 Laser (sounds like a bad beer) and had it reading CD-Rom (burned games) for all of 10 seconds, and hasn't been able to read them since. Audio CDs boot instantly, I tried tweaking the pots.. am I being too fussy with the back-ups? It's a derelict system I picked up in Japan and had high hopes. The laser I bought wasn't cheap at $26USD hoping to find a replacement on a budget if nothing prevails

I think someone mentioned previously that that replacement lasers can be hit or miss. I know I've had mixed luck with them too, I bought like 15 Saturn ones in bulk from china and maybe only 2/3 of them work.
