Broken PET

[Shaun_CCC(UK)]

Hi,

I have a poorly 4032 (UK model), and this is booting up with a screen full of zeros. Does anyone have any tips etc... about this?

Update: Actually, the screen is filled with garbage first, and this it fills with zeros. I didn't see this because my screen hadn't 'warmed up' enough to see the garbage. I quick on and off and I noticed.

Thanks,

Shaun.

     Shaun, have you tried reseating the chips and any boards in the machine?

Yes I have. I think I now have the right combination of 'working' chips with the exception to the Screen RAM which are soldered in. I need to replace these.

Regards,

Shaun.
