Help LCD issues on G1


Hi all. Been having some issues with my G1. I purchased it on Craigslist for a good price, and want to fix it.

My screen will ocassionally not work. When the phone locks the screen will not come back from sleep. Sometimes when I turn the phone on it simply won't display.

Now I've heard this might be a problem with the sliding mechanisim and the ribbon for the LCD, which I would like to fix, but I've also heard it could be the touch screen or the LCD. My LCD isn't cracked, when it displays it displays fine. I just don't know what the issue is, and would like to solve it so I can actually use my G1!

Thanks Guys
