If it only flickers when your using an adapter then its your adapter causing the problem not your GP2X. Cheap adapters cause a lot of interference on the GP2X, this is what your seeing on the LCD.

Get a regulated adaptor and apparently squidge had to run his at 4.5V.

I think you'll find that was Reesy, not me

 

[sliteist]

yeah im running it at 4.5v and now it want boot up without the adaptor S*@T

Real slick, you just broke your gp2x.

Somebody should tell Reesy before he breaks his!

My GP2X must be well ard! but point noted I won't be testing it's ardness any more.

The same thing happens to me. With the AC Adapter I have, it has multiple settings: 3 volts, 4 volts, 5 etc. If I try it on 3 it gives me the multi colored lines that you get if your batteries are dead and if I turn it to 4 it boots and works but the screen flickers. Maybe it has to be 'exactly' 3.3 not 3 or 4.

With my bricked unit if I only gave it 1A the screen would go crazy and flicker all over (this is at 3v) but when I tried a 2Amp adapter it showed the screen just fine.

Cheap adapters don't change the AC to Dc very well. The circuitry leaves in alot of ripple (fluctuation left from the AC sine wave) and can cause flickering and waving in the display. No adapters can totaly get rid of all ripple but good ones minimize it.

I tried a Radio shach 3V and 500 MA adapter and it worked. That is strange that some of you need 1 or 2A and more than 3V. Must be something with the adapter.

500ma? I know that is not going to be enough to power the gp2x, doesn't it take like 800ma to play video and 1100 with tv out?

my gp2x runs fine, my lil sis put cheep ass bat's in it witch is why it wouldent boot without the adaptor i guees ill just put up witht the flicker.... not too bad, might have a fit though hum.... what radio shack one is the best....

thanks

Yeah, that makes no sense.

I got this one its 2 amps

But this one is good too because it is regulated it is 1 amp, it is more expensive but comes with LOADS of adapter head things

Either one should be fine. The bottom one might be better because it is regulated, but the top one has more amps and with more amps you could over clock higher (right?).

the adaptors posted here tend to all be expensive. I've even heard some people giving insane figures as to what a universal AC adaptor should cost.

for people in the US, this one is under $10 and works fine. No more wavies than usual and the tweaker makes them go away just as with batteries. It has a 90-degree plug for ease of play as well (but the cord is slightly shorter than I'd prefer).

it outputs a regulated 3V@1200mA and easily adjusts to have negative on the center pin. (for some reason, many don't) Should be a chainwide item.

we really should have a sticky topic for inexpensive helpful accessories.

^wow that does look pretty good. Oh well I had loads of Radio Shack gift cards I need to use up.
