1 second power off - Game Gear

[guyinahat]

Game Gear is turning off after 1 second, i have not modified the console, i am wondering what modification to start with, should i replace capacitors or something else?

Have you tried it plugged in? Actually I don't own a game gear so I'm not sure if it even has a charger or if it just uses standard AA batteries or whatever. If it does have a charger, trying running it plugged in and see where that gets you. If it just takes standard disposable batteries, I would hope you already tried swapping them out

i did with ac adapter and with batteries

EDIT: and also with and without cartridge

Okay, hmmm strange. Do you have a multimeter to test the current and voltage coming out of the ac adapter? It could be a faulty plug, that could've fried something inside the game gear. Working in IT i've seen this happen far too often with laptop chargers that went bad that were outputting way too much current and frying people's motherboards.

Oh ok, well that would be your next step

Tested, 13.8V from he power adapter.

What's the rating on the power adapter? Is 13.8v close to what it should be outputting? I don't own a game gear myself so I can't check . Also make sure its outputting the right current (of course it won't be exact, never is, just like voltage or anything else, but it should be close to what its rated for).

Game Gears operate on 9V.

Game gear powering off after a few seconds is a common manifestation of the capacitors going bad (same issue that causes the audio to go out). The vast majority of game gears will have their caps go bad by now, so that's likely the case. There's people on e-bay that will fix your game gears, or trade-in your old one in purchase for a new one that's already been modded.
