LED Mod GT With LED's Reclaimed From Old Camera LCD's

[daedalia]

I read on benheck that some fellow made an LED mod to a Game Gear and it increased the units battery life to 10+ hours. There were a couple of blooms on the screen but it was impressive never the less.

Anyway I got to thinking about it recently as I've had a few bust cameras through work. The LCD's are a similar size to the PCE GT screen, so I tore them apart and managed to seperate the LCD from the LED's and light distribution panel. If I can figure out how to power the panel and maybe even dim it then they should act as really good and power effiecient backlights with perfect light disribution.

My electronics knowledge is unfortunately pretty poor so is there anyone with some expertise that can at the very least point me in the right direction?

Thanks, Bryn.

you have the right idea.
all you need is a resistor from the 5V circuit.
select for brightness

is anyone actually doing a mod like this? I would love to have my GT's screen replaced with a modern new LCD.

One thing though, a guy was offering this mod for Nomad's over at digitpress once. He said it was only possible because of the Nomad's video out signal. How would this work with a GT?

Someone has done it on this very forum, have a look below:

I may do this now as I've dropped my PCE on concrete and the case isn't mint anymore. Didn't want to destroy a mint unit doing this mod. I still may try this in a few months, I need to refresh my electronics knowledge and finish my arcade table first.

for best results you should use a difuser of some sort.
you could usa a pen with a round cloudy barrel for a difuser

If you look at the picture in my first post the plan was to use the LEDs and diffusers from old camera LCDs. That way I should get top notch results. I'll probably do the LCD swap now though.

i know.
i was just pointing out that other LED's and diffuser's could be used

Awesome. If someone wants to make a few bucks, I would pay to have this done to my GT.
