Power on but no image no sound

I found my old game gear, i forgot 2 batteries in.

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.

@Principe Motociclista Can you follow the Sega Game Gear Capacitor Replacement guide up to step 6 and tell me your version(VAx) and board number(837-XXXX)?
