Game Gear LED mod & cap change

[mjnurney]

Mr Cosmic sent me his Gamegear ohhhh months ago so i have finally got off my large rear end and repaired it here are a few pics.

Faults
No sound
Dim picture
flickering picture.

some details:
2x LED (white) 3v , BIC pen with sides sanded to produce a diffused glow. bundle of caps 3x100 2x4.7uf for the Audio circuit.

And now.
Sound and picture is now bright although i dont think the game gear has the best LCD.

anyway pics...

Unmodified GG: 2 hours, 40 minutes
LED-modded GG: 8 hours, 45 minutes

little Youtube vid with my Master system convertor.

great mod mate good idea with leds

love the bic pen for the LED's. I had an LED modded Game Gear (bought it pre-modded) i sold on here a little while ago but instead of a bic they used the original glass tube from the original light.

i didnt fancy opening the glass tube but i may try it on mine

There are LCD replacement options, the Nomad used a reverse camera screen from a car so i'm sure you can do the same for the GG. However, you might like to look at this...

yes i was looking at the Australian RGB out mod and the LCD replacement from a reversing camera but as its not my gamegear and im not really a fan i wont be doing it..

unless i get an LCD cheap..

Nice work Mike

(I have a spare faulty GG if you want one to test on)

Nice work as always, might have to ask you to do mine, it was supposed to be fine, but when it arrived no sound and a really bad picture, so Ive never used it.

Is the power consumption much better with leds?

 

[mjnurney]

sure guys and yes power usage is 5 or 6 times longer ....they say....

its a little bugger to do and the caps leak very badly.

Ohh just found this thread while looking for backlight replacements for my GG, mine's almost packed in (very dim or just flickers ) I've owned her from new but I don't use it that much as it eats batteries and the psu ties you down. But it look's like the LED mod could sort this all out, I've seen the mod on a couple of sites, but really like the bic pen fix , I've also seen a Nintendo ds screen used but that look a lot more complex. I do have a question though on a the other sites a 33 ohm resister was used in the circuit ( i.e. http://tibia-mod.dreamwidth.org/486.html) is this not really needed ?

 

[mjnurney]

Some people use it and some don't , it doesnt seem to be necessary.

Could this be done to an Atari Lynx II?

Mainly the LED Mod.
