Hey so I've recently installed a white backlight onto my Gameboy Pocket.

Before installing the backlight my Gameboy Pocket would run every game including LSDJ.
However ever since I installed the backlight LSDJ won't run, everything else runs fine and as it should except for LSDJ.
My LSDJ cart btw:

The contrast is super high, setting it to the lowest just about shows the Nintendo Logo WHEN it even shows up and it never goes anywhere from the bootup!

I'll note down what I did to the system that could potentially be seen as the problem. Because I don't think the cart is the problem, it runs on all the other gameboys I've checked. Just in case there's an incompatibility thing I don't know the code on the back is CN9804

First of all I bought my backlight kit from http://www.deadpanrobot.co.uk/en-gb/col … -kit/75777
the white one. I did a clumsy job installing it but the screen still seems to function and runs games like Pokemon well.
I followed this soldering guide of sorts: http://handheldlegend.com/pages/hhl-help-forum

That's about it, all I did was a backlight mod so I'm convinced that something about the backlight is hindering LSDJ.

I just don't know personally so if any of you have any ideas please help out if you can! hmm

Sorry if this is basic knowledge but this is really jarring 2 me hmm

Thanks 4 helping out if you can btw

Did you use resistor or just wire to +5v pin? My DMG crashed with lsdj without currency limit resistor.

The backlight has a pre-installed resistor.

Try adding another one. It just sounds like too much current draw. Internal resistor could be shorted, for example.

Alright I'll give it a try.

That seems to be a funky spot to install the backlight power. It's right on the edge connector. I'd re-wire it following this guide: https://www.youtube.com/watch?v=i0PlML-q4Lo

I have white backlight from Deadpanrobot too and it came with loose resistor you solder yourself.

LOL it makes me feel so proud that everyone's using my 5V soldering points picture after HHL posted it on his website
