I picked up a used GBO on craigslist for my kids and it had the missing vertical lines problem. This one happened to have several dead lines on both of the outer sides of the screen. It was the problem where if you push at the bottom of the screen just under the dead lines, some of the lines reappear.
I am often able to fix this specific problem if it's not too bad by quickly and gently rubbing a hot blunt tipped soldering iron against the ribbon cable that connects to the bottom of the LCD screen. In this case i was able to fix the right side completely but I got sloppy and slipped while doing the left side so my soldering iron went under the ribbon cable and tore a few of the attached circuited wires.
Not much I can do now but buy a new GBO. I was hoping though, that someone here might have a bad one or broken one they would give me or sell cheap. I will of course pay shipping in either case. I will make any payment in advance before you ship and prefer PayPal but can send a MO, too.
The GBO has two main boards inside. I only really need the board with the LCD screen attached. I do need this part in working order, though, if possible. I might be able to swap some parts from mine. At the very least the LCD screen and connecting ribbon cables should be working and intact. Even if it has a few dead lines I might still want it. As I stated, I can usually fix this particular problem. I just need to slow down a bit next time, hehe.
I know it could just be easier to buy another GBO since they are so cheap. I was just hoping a replacement part might be even cheaper. Seems a shame to toss this GBO just for one bad part.
Thank you!

P.S. Great site, can't wait to look around even more.

Sorry for rambling on. I didn't realize how long it was until after I'd posted, hehe.
