Gx4000 help, please

[Beaps]

Hi all


I have 3 GX4000 that dont work, I have tried swapping ram chips, swapping z80 etc and still no joy so I gave up. I then decided to buy another and.... again no joy. So now I have 4 consoles all not working.


Any willing to take on a challenge and fix these, I only need one so if you get one, willing to pay or work out a deal.

Are you sure you aren't frying them putting more than 5v in the 5v socket, using a power supply with reverse polarity or something like that, getting 4 dead consoles seems awfully bad luck.
