Re: Broken Plus/4: what's wrong?

I received a "new" Plus/4 today, and tested it using a C-64 power supply (it has the same round DIN power connector as a C-64) and a 5-pin C-64 A/V-Cable, both known working.

When turned on, it produces a video signal, but the screen stays in one single colour -- most of the time black, but sometimes also light grey or purple. Can someone point me in the direction as to what is wrong? As first guess, it could be any number of things, the CPU, the TED, the ROM, the glue logic...

Thanks!
