Removing the back cover and fixing an unresponsive touch screen.
My daughter decided to drop her 80 Cobalt leaving the screen unresponsive but not broken.
After re-flashing the firmware and ruling out a software issue, I decided to open the case and have a look inside. With a bit of playing about I discovered the matt plastic back panel can easily be unclipped from the shiny plastic surround.
First remove the single tiny crosshead screw from under the sdcard flap. Then unclip the panel using strong fingernails or a thin plastic tool. Work from the speaker end and hinge it up at the camera end as there are four tabs there that locate under the curved shiny plastic part.
Inside there are two rectangles of plastic sticky tape in the same place, under one of those is the touch screen ribbon. I removed the plastic tape and found the ribbon was unseated, I just pushed it back into the connector and replaced the plastic tape, which appears to be the only thing holding it in place. The touch screen sprang back into life.
Replace the back cover and small screw. Job done.
It should only take a few minutes to repair.

I've stripped my phone down and removed the lcd digitizer and it was held in by what looks like thin grey double sided foam tape, I have a new unit to fit but it doesn't come with any tape.
Does anyone know where I can get some proper tape to hold the screen in?

My screen just shattered yesterday after a drunk night out. I went and ordered a replacement glass from ebay since I'm assuming that it's the glass that's only broken. The touchscreen works fine. I can still use it normally. I have a few questions before I begin. I've watched youtube videos on taking the phone apart. I've read a bunch of threads. I just want to be extra careful.
What do you use to keep the new glass onto the lcd screen? I saw some 2mm 3M adhesive tape. I read that it'll make the screen very sensitive. I've seen people reusing the black adhesive tape it came with.
The tools: Hair dryer, small Phillips head screw driver, metrocards, guitar pick, plastic pry tool, razer blades, rubbing alcohol.
Random though, has anyone bought a different colored glass from their original color? Grey glass with white home button and vice versa. Seems dope lol.
Thanks!
Story: Friend cracked phone. Tec school classmate replaced the screen. She got hair and dust under the screen, and I mean enough to have the screen be pressed down to distort color a lot. I took my screen off, cleaned it, and I need the adhesive replaced. The screen holds but I can still peel it off using the speaker gap. I want it stuck on like new again.
What adhesive size do I buy? And preferably from ebay.
This is the adhesive I used last time I changed my screen. 2mm.

I just noticed while cleaning my phone that the top glass panel got some liquid inside it. Asked the local service center if they could remove it by just detaching the glass strip(is it possible?), cleaning the surface, and reattach it again. He said it isn't possible and they'd have to replace the entire housing. T_T couldn't attach pictures yet because I have the only camera phone in the household. It doesn't seem to be affecting the phone performance-wise. I just don't like seeing the liquid 'stain' inside the glass strips.
After the digitizer connector is snapped into place and screwed down, is it wise to test it before applying adhesive or does that little strip that sticks out to the side (for grounding) have to be firmly placed/taped down first? I basically want to be sure the screen works before adhesive and tape are applied. Good or bad idea?
Update: Dry fit went well for testing. Used a precision-cut adhesive and peeled off the protective plastic after testing to seat the new screen replacement. Cracked But Not Forgotten brand. Zero problems.
