Spectrum +2A problem
Working my way through a new influx of greys and blacks i came across one thats got me a little stumped, on boot it goes straight to vertical black and white lines, nothing ive tried gets me past it. so far ive tried replacing ROM, Z80 and RAM to no effect. This board had been water damaged sometime in the past and some connections on the board were either rusty or had corroded blue, these i have re-done. A bit stuck now
