You need to solder a cable from the ribbon cable adapter to a ground point on the GBA.

Turns out i was sent the wrong adapter

What's the difference between a Type A, Type B, and Type AB screen?

Hello there, just registered for this project too !

It seems there is 2 version of AGS- 101 screens (LG and an other one) . Someone who bought a screen from Zerey Zhang knows if he sells genuine screens?

Thank you.

Look at the ribbon cable

Oh which do you have and how much?

I have 2 revisions of both cables which do you need?
Post a pic of the cable you have.

Hi everyone, im not sure if this is good board for my problem, but im sure it's releated

I recently bought screen for AGS-101 and adapter for 32 pin AGB-001

I put together all elements, i soldered power cable for backlight, however I can't get nice picture, all I got is phantom of the images displayed in weird colors, looks like missplaced color hue, plus some smudges on left and right. Basically I can't see anything, it's unplayable.
For now I switched back to original dark screen.

i double-checked the connections between GBA - ribbon - LCD
what could went wrong? maybe my fault is i didn't bought the kit from Zerey

LCD is NOT original AGS-101, it's a replacement. Could it be a possible reason?
i have ribbon from http://www.aliexpress.com/snapshot/6124721337.html
and LCD from http://www.aliexpress.com/snapshot/6125419754.html
my GBA is model "10-" (32 pin)
So what's the problem? Is it AB/B screen incompability mentioned above? Should I sell screen and buy another one? Or maybe there is way to swap some pins to get proper picture? I'm good at soldering ;]

Let's try connect some pins to GND. Good lucks!

Have you tried to adjust the pot?

 

[YunGBA]

Have you tried to adjust the pot?

Yes, i tried. It only makes screen darker/brighter and it removed some ghosting in my case.

Then I'm sorry, I don't know how to help you further.

Use a different ground

 

[YunGBA]

Use a different ground

Please be more specific. I have no idea how the ground could be "different". I really want to make this screen working properly

Where the yellow dot with red line is

Where the yellow dot with red line is

Still no idea what you mean. I might be blind or stupid as well ;] but i dont have such marking as "yellow dot with red line", all i got is white/green mainboard and copper ribbons.

Where should I look for it, GBA mainboard or LCD? What should I solder to what? Would you upload some picture with it?

Sorry for being pain in the ass, but you haven't been clear.
