Title: Repairing a PCE CD system (Briefcase version)
Post by: Oli_lar on April 17, 2007, 03:19:40 AM
As the title says I have a briefcase system I'd like to try and repair - when I put a CD in and press run it just keeps on spinning, stopping after a while and then repeating that. I played music CDs in it and it was fine.

Anyone have any suggestions?

Cheers

Try tilting it on it's side or something. Sometimes this helps when I run back ups on my PCE CD.

This one dude said he had to turn the system upside down until the game starts, then it ran fine in regular position. must be some problem with briefcases, haha.

These particular systems are extremely dodgy. Repairing it is probably not going to be easy.

hmm none of those suggestions seem to work - I'm using the system card ver 2.1 - is that right?

When I press run and the cd tries to load the screen goes wavey and kind of repeats itself a an inch lower too....

Hi,
Do you use the Original Power Unit or not ???
Because you need a 9V 1500ma power unit for your IFU.

Your problem could be power like the previous poster indicated, but I've personally seen your symptoms as a result of using a dirty System Card.

Yes, a System Card can be just dirty enough to load to the title screen but not properly load the CD game into RAM. When this happens it will produce effects similar to what you've listed.

Get some fine sandpaper or a metal nail file and gently buff the contacts on the System Card so they are really shiny. Use a damp cloth to wipe off any filings and, of course, let the cart dry before trying again. It doesn't hurt to use a little alcohol on the contacts, too, but sometimes alcohol alone isn't enough.

No I don't use th original, I'm using a multi voltage set to 9V, but it says 800Ma max - is that the problem?

Cleaned the system card with a bit of nail varnish remover to no avail, I'll get a bit of sandpaper tomorrow in town...

Sure, you need a 1500MA power supply, because if you use less, cd spine but it's not enough for have a good cd reading !

Your PSU is definitely the problem. I used a weak third party PSU with my PS1 once. It could read music CDs just fine, but games just didn't want to work. Got a new original PSU and everything worked great.

After reading this, I concur with peperocket and Seldane. You need a proper power supply. This is most definitely your problem.

I've had a similar experience with a sega cd where a better psu fixed the problem.

 :clap: cheers guys. I have a UK step down converter (Jap out) so should I get an original NEC power supply, or is there a cheaper 3rd party option?

Thanks

Any 9~10v adapter will be fine, as long as it has enough amperage. And the polarity on the plug is the same of course.

Got a 1200 mha adapter and it works! Strange that the other one would power it but not be able to read games...

With Dracula X, how come theres a strange cartoony stage instead of the usual game? - Didn't happen on ME..

That means you aren't  using the right System card. You need at least 3.0
