ZX Spectrum repair, restore and upgrade. Part 2

In part 2 i look closer at what is causing this ZX Spectrum fault. I remove the lower RAM and upper RAM and test the ICs before investigating the main issue in the power circuit.

There were enough clues in the previous video to work out what was broken on this board. In fact it was an easy fix and common fix in the end.
