Should I Return My Gp2x?

[garteth]

right, I have one of the first edition gp2xs, ordered around 21st of september. It arrived and worked fine with the first firmware no flickering or anything that I could see but it seems after upgrading to any later firmwares I get either flickering or diagonal lines. I have tried tweaking it with the CPU/LCD tweaker, the best setting seemed to be UPLL -3 but this leaves a whiteline at the side of my lcd screen and the flicker is still there albeit a little bit better. The flicker is a lot more noticeable in gngeo on the green startup screen. I don't know if this is a firmware or hardware problem but it seems unfixable atm. Any ideas welcome

thanks

I'd say that if it happened after a firmware update it's certainly a firmware problem. Try firmware 1.1.0, my first ed unit works just fine with that.

I dont remember the settings, but Iorgy77 suggested a good way to set the LCD so you get very little flickering. After entering the tweaker, press B once and volume+ twice, then select to exit the app.

this is UPLL +2, anyway I prefer UPLL 0

I've tried all those settings and I still get a flicker or some kind of shimmering effect on the screen, I dont know if this is a flicker but it is quite annoying.

Just thought i'd tell everyone that I managed to get rid of the flickering by downgrading to the 1.01 firmware, I still don't know if this means it's a software or hardware problem but my gp2x is now useable. I had to borrow an sd card to downgrade as my sd card doesnt support firmware updates.

Hmmm, you got rid of the shimmering, too?

 

[Trashman]

you havent really told us which firmware version you were using to start with. Mabye 1.2.1 would help, who knows? Give more info for a better solution.

EDIT: mabye this post should have been in the help section too!

I think there may be still a slight shimmer but it's hardly noticeable, I am going to try tweaking it with the LCD app
