Hi all, I'm still here. I got a little frustrated with the machine so I set it aside for a bit. I think its about time I tried again.
Last time I powered it on vertical lines were still appearing on the screen. I'm going to experiment with cold starts again. The switch is broken again, and I think it's time to find a new one. I think I may have found a suitable replacement, but I'd like your input before I buy it. Here's a link: http://www.mouser.com/ProductDetail/ALPS/SPPH210500/?qs=nco%2F1JLdfbfGKznkyM%252bWfw%3D%3D Thanks!
