Game gear problems

[SuperNES]

My game gear powers on, but the screen, backlight, speakers, and headphone output are all non-working. the red power LED comes on, but nothing else. i suspect it's a problem with the power, not the components themselves. i used fresh new alkaline batteries. can anyone help me?!

Try cleaning the cartridge. Its a cliche, but since I doubt all the part would be broken, and since power is getting to the LED, its the most logical explanation.

hmm, i'll try that. but would adirty cartridge cause the backlight to stop working?

Maybe the contrast is way low?

[SuperNES]

nah, tried that.
if you turn on the gamegear with no game in there, what happens normally? it could be I have a broken game. unfortunately, i only have one game and no other gamegears to test it with.
