G'day i have had a Japanes AES for a few months and there is a graphical error that i'm wondering if it's caused by lack of power?
Anyway the converter that was included is..

Input 100-240 volts
50/60 Hz
Output 5VDC regulated
Current 2.5 Amp.

It seems to have a problem with a certain zooming grey graphic across all my games.

Any help would be appreciated.
Thanks.

Look at the bottom of the console. There should be a label with the model number, type of AC adapter and the serial number on it. Can you get a shot of that?

It's better if you open it up as it could be a reshelled system.

Pow 2 is +5v@3A. Make sure it's center negative.

Yeah, not enough current from that converter.

Well, if he's using something like a Phantom-1 to play MVS carts then the current draw of the converter can increase the required power significantly beyond what the AES normally pulls.

But if it's an NTSC-PAL or a CRT/HDTV problem, then that's not something a converter can do to help.

Sounds more like his PSU is failing in general. But if it's only doing it during zoom it could be a corroding trace.

Thanks everybody, i might buy a new power supply anyway, just to be sure!

Thanks for the help and i'll post again once i have the new supply to let you know if the problem persists.

Sounds like it may be time to take the shell off and check the board if the new PSU doesn't work.
Thanks man.
