Troll, trolling? Sorry don't know what that means

Battery contacts are perfect and it won't work with New batterys and I also use 3volt adapter plug which powers all my other units fine but won't power up this one.

So is there anything else it could be?

Right start again.
You said the fuse is inside the power switch.
Iv already taken the power switch apart.
Its not blown.
So I cleaned the contacts within that power switch.

I had another game boy not working because inside the power switch it was dirty. I cleaned it out and it worked fine.

Yeah I took that all apart already And cleaned it all out. All the contacts in there where fine. So it's not that.

No I havnt even tried to install a front light on this gbc,
I was just trying to fix it as it wasn't working when I got it.
I will Check the power switch fuse though,
But where is that? And how can I check it?

Hi all,
I've done a few front lit game boy colors now and they have all gone well.
I recently baught a gameboy color to do the mod again but It was faulty,
The fault was it wouldn't switch on...
Usually a good clean is all I have done in the past and it will all work fine.
But on this gameboy color iv tried so many things to try to get it to switch on and nothing has worked.
When I flick the switch the led power light flicks on for split second then goes off.
My question is, has anyone else had this problem and managed to fix it?
Is there a resistor or compositor that could be faulty that I can replace?
Any other tips or advice would be appreciated.
Thanks in advance
Danny

I managed it, it can be done, to fit a variant A back light into a game boy pocket, it's very fiddly and I had to modify the housing a little.
I wouldnt have thought many people would want to try this mod so I won't go into detail of how I did it. But if any one does want help with it then I'll keep a watch on this thread. Cheers for every ones help

Ahh I've seen the light! brilliant that answered another question I had lol
Thank you very much
I will give it a go when I get chance and report my findings incase there's anyone else who's trying to cram a variant A back light into the extremely slim gbp
Thanks again I realy appreciate your time to find that info for me.

Blue and green? I'm guessing the documentation explains? Because all I got is 3 black wires and 1 red.

Ah thought it might be you with a name like that lol.
thank you for the link too.
I baught these because the wording on the website gave me the impression that it was possible.
But not to worry. Just out of interest , is it possible to wire Variant A and make it work for a game boy pocket ignoring the fact there too thick? (as in I don't mind if the case can't close once installed?)
I'm just not sure on where to solder it on the pocket game boy and whether or not I need the resistors soldered on too?  And would trying it damage any of them?

thanks for quick reply
I baught them from kitsch-bent.com
These have 3 black wires and 1 red wire, making it possible to make different colour on the back light.
They also came with 150 resisters and 220 resister.

Hi I'm new here, and seeking a bit of advice

I've been modding game boy pockets with back lights, and have been quite successful
i must have done about 15 of them now,

(i was installing the back lights which have a black and white wire coming from them.
I'm not sure what version they are.)

but i recently bought variant A back lights which are used with the DMG old school game boys

is there any way to install the variant A back light to a game boy pocket?

I've been searching the net high and low and cant find anything!

Thanks in advance
