Title: White PC Engine not switching on
Post by: nozza on January 09, 2016, 04:07:49 AM: Dear all,

Need some advice if that's ok, I bought a PC engine some time ago and had it converted to run a scart lead, it seemed to work OK but all of a sudden it now doesn't work at all. I've taken apart the case and noticed that the fuse glass wasn't clear and looked like it had some staining inside, I'm presuming it's blown and needs replacing, as I'm from the UK does anyone recommend a fuse that I can use?

Thanks and sorry if this type of thing has been posted before.

Regards

Also if you want to get the same kind that is in there:

Its ok to replace it with one rated at 250v

I only have Chan and Chan, Jackie Chan and Tatsujin but those were the games I loved playing when I was younger round a friends house. I think the fuse may of blown due to the plug that I used, it was a multi adapter/wattage one, think the settings was wrong. I realise that a MK1 Sega Mega Drive (Genesis) one will work on it, but please advise me if I'm wrong?

Thanks again all.

Not sure if you had to many volts set or something but I would pay special attention to how the ends are polarized on the plugs.

Post by: nozza on January 10, 2016, 03:41:30 AM: I have a feeling I messed around with the voltage on the plug after getting it back after the scart mod, so it looks like it was my fault. I've got a genesis power supply so will try that after I've replaced the fuse, the rest of the motherboard looked in good condition, just a little dusty of which I will clean when I do the repair.
