Mine won’t start at all (actually I have two with identical wobbling screens) - I have 4.6V on both. I shall recap the logic boards anyway and report back, since I note that the voltage jumps to 5.3V with the logic board disconnected. PP1 measures 200 ohms to 0 or thereabouts.Hi Alex,
I haven't switched it on for about a month so I'm no further ahead! Sounds like you have changed most things! Do you have the resetting problem too?
