Hi guys!
Few days ago I bought AGS-101 LCD (white connector) to my 32 pin GBA. Connected it to adapter from Zerey (with single wire only to backlight) and everything looks fine expect one thing - scan lines. I tried "playing" with potentiometer, but I am unable to turn them off permanently, they just always are, sometimes more, sometimes less. For example, when playing Metal Slug and jumping, I see horizontal, light bars. When not moving, everything is ok. Is it LCD fault? Or additonal wire to sovle it? Or maybe potentiomete fault and I just have to change it?
Thanks.

adjust the potentiometer while the game is on, and test it during all those cases. When I did mine it took me a little bit to get it right.

I know, but is it possible that is is so precise to do this? I will continue trying, but damn! Anyone know best game to test this issue? I know about grey background, but something more?

Ok so I have a type AB screen (Brown Tab) and a 32 pin GBA. Can anyone recommend me a ribbon cable adapter on eBay? I'm fine soldering if I need to. I keep looking on eBay and a bunch keep saying they will only work with one type of screen, and that worries me that I might get the wrong one.

It might be impossible to find a seller who knows difference between ribbons for third party LCD's or Original Nintendo LCD's, when I make a question about this (on aliexpress or ebay) they answer me with absurd answers.

I ended up pulling the trigger on lee_chan1985's 5-brightness level ribbon adapter. It's the one where you press L+select to cycle through the brightness of the back-light without having to install a switch.

When ordering, I ended up sending him a couple pictures of the LCD I'm using, as well as the GBA's I'm installing them into:

I have both version of LCD's as well as both versions of GBA's to throw them into. His communication was precise, and he let me know exactly what I needed for both combinations.
The ribbon adapters are on-route right now, so once they arrive and I can install them, I'll post my results here.

for gba on 40 pins , about brigtness and contrast, some people have again probleme
so i try a different connection to 32 pins, and it s great. if you have a lot brightness or bad contrast,

Yes, you're right, I forgot to mention to leechan but I think 16,50 USD is too much(due to the switch brightness), but at the end I will have to buy to him.

Thanks for your reply.

 

[Cheekee]

Ok so I just basiccally have to order it, and hope it works?

Yup, like any non-official hardware.
Just make sure you order the right one for your needs, and if it doesn't work, I'd contact the seller and see what he/she can do for you.

so if i have gba with 40 pin cable i dont need to buy a other cable from the internet to put the sp screen in gba right?

I'm hoping to buy one of the ribbon cables sold by gbaguan, and from looking at their listings on taobao here:-
https://shop103264363.world.taobao.com/
It appears they sell 4 different types of ribbon cables for AGS-101 screens

Standard cable
http://world.taobao.com/item/17953133877.htm

Professional cable with brightness switch
http://world.taobao.com/item/24351408753.htm

Aurora Luxury cable with brightness switch
http://world.taobao.com/item/24351728191.htm

Aurora Deluxe "Rainbow Edition" cable with 5 brightness settings which you can cycle through using L+SELECT
http://world.taobao.com/item/39228683802.htm

Each cable type is available with the following options to match your GBA motherboard and AGS-101 screen
-32 pin cable
-40 pin (A) Screen
-40 pin (B) Screen

My question is what exactly is the difference between the Professional and Aurora Luxury cables? From google translate I get the impression that the Aurora Luxury cable includes power stabilisation circuitry?

I would just have just chosen the Aurora Deluxe cable, but after reading pelago's post

One thing to note about this cable, which I hadn't considered before - every time you power off and on the GBA, it will default to the lowest brightness level, so you will need to press Select+L sufficient number of times to reach your desired brightness. I had thought that it would remember the previous brightness level, but I guess it has no non-volatile memory.

I just know that it will annoy me having to reset the brightness level every time I turn the system on, and to be honest I think two brightness settings would be enough for me.

Incorrect. Even if your AGB-001 motherboard has a 40 pin connector, you will still need an adapter cable. The pins don't match otherwise.

My question is what exactly is the diffferent between the Professional and Aurora Luxury cables? From google translate I get the impression that the Aurora Luxury cable includes power stabilisation circuitry?

Yes, I think it is something to do with power stabilisation. I read somewhere someone trying to play games from a GBC flash cart on a modified GBA with one of the cheaper cables, and it kept having problems, which I think was due to the extra power requirements of the flash cart. I believe that the more expensive gbaguan cables fix that problem, but I haven't tested this myself.

I agree it is annoying that the Select+L cable forgets the previous brightness. Ideally it would remember the previous brightness, but if that wasn't available, it would have been nice to be able to set a default preferred brightness using jumpers or a little switch or something inside.

I'd like to order from there too but the seller speaks no English, so I guess you'll have to settle for a taobao agent, those are pricy though :/

Luckily, there's an ebay seller, lee_chan1985, who speaks English and is reselling the gbaguan cables, or at least some of them. See my post earlier in this thread.

So do you still prefer the rainbow cable to the aurora one?

Well, I've only got the one cable so I've not compared the two side-by-side. I'm not sure how the brightness levels on the five-brightness (Select+L) cable compare to the two-brightness (battery compartment switch) cable. It might be that the brightest level on the Select+L cable is brighter than the brightest level on the two-brightness cable - I don't know. Although it's annoying having to set the brightness when you switch on, at least you can do it while a game is booting up for example, or in the middle of play - it's not like the 3DS where you would have to go into an option on the home screen and interrupt gameplay.

I dunno. From the videos posted it looks like the brightest lvl on both of the cables are about the same. If the brightness lvls were the same, would you still pick the rainbow over the aurora?
