A lot of acid come out on the motherboard i clean it with isopropilic alcool most corrosion is on the back of dpad, if i plug in batteries or the power unit the red light is on but no backlight no picture no sounds.

Any advices ?

Thanks

Have you recapped this unit yet? Many Game Gears suffer from bad capacitors and the capacitors themselves can cause many problems.
