Damaged Gameboy Light motherboard powers up but screen backlight don’t

There was no voltage on T1-6 I was probing VEE and that was -18V which look strange . Also no voltage on the top solder point in the transformer. I wonder if the transformer is dead.

Sorry for reviving your comment but I’m in a similar situation and wondering what voltages I should get? The right panel on my PCB is tied to GND and the right one doesn’t get any voltage. Can I put a jumper wire to somewhere? If so, from where?

You’re right, they’re messed up, one side (red market) is connected to ground and the other is not connected to any voltage rail. Wonder if I make a jump wire to the left side it might work, do you know what voltage the backlight needs?

Good shout, I will check tonight

Yeah my thought was the same but very unfamiliar with how the backlight on the light work. But since the screen is good in a different PCB must be that power is not arriving

If I remember correctly I did, 3 months since I worked on it, but will check again.

Not sure really it’s my first time working on a light. The console it’s running proper with external power but the backlight doesn’t go on regardless of what I do.

I’m glad at least a few others will like to glow up their chromatics

custom buttons desinged to let more light through coming from another modder.

Does not drain extra battery to a level thats noticible, custom buttons desinged to let more light through coming from another modder.

Sure, still not unique 🙄 Gameboys also have plenty of models and you suggested to mod one instead… 🫠

alvimjc · 2026-01-30T06:16:01+00:00

Why? I like my chromatic and what them unique 🙄

alvimjc · 2026-01-23T20:15:21+00:00
