Hi All
New to the forum, but been on IRC over the past couple of days talking to some of you, also a big thank you to the mod who authorized my registration, dont remember your name, but thank you for doing it!
So last year i had my Plus set up at my GF's for gaming and writing entries for my vintage computer blog. Only two months in to using it, the more computer began to show signs that something wasn't quite right. Finally one afternoon the screen went out and it didn't come back on. I assumed this might be the capacitor located at C1 on the power board. I followed a Plus repair guide i found online, Jags House i think and sourced a 50v non polar cap and replaced the existing one, which had no signs of bulging. Turned the system on and nothing, the screen did not fire up, i dont even recall whether it produced a 'Bong', I dont think it did.
Not knowing where to go next, i bagged the Plus up and put it in the attic until i could find a replacement analog board or an answer to what the heck was wrong with the machine. Then recently i read something that gave me hope. After the repair, I had neglected to check the voltage coming from the external floppy port, if it wasn't reading 5v and 12v, the machine probably wouldn't boot up. So I've taken it from the attic and hooked it up once more. This time the machine chimes with a clean 'Bong' however the screen is still very much dead. I checked the external floppy port and it reads 4.97v and 12.17v, I ran a line test on the yoke connectors on the power board and they appeared fine. I was wondering if the screen wasn't receiving power, however if i cut the power at the wall and not the switch on the rear of the mac. I can hear the fizz of the CRT as it discharges.
I'm really hoping someone might have some advice for me, so i can revive this system.
Cheers
James
