[Nook Color Q&A, Help & Troubleshooting] AlienBZ:
the other day i bought on ebay what I thought was a good bargain - nook color front panels for $6 each

nook color LCD + digitizer assemblies

so i bought 3 of these panels with the understanding that they didn't work because the digitizer was broken,

Now, here's my 2 scenarios that I have in mind as my proposed attempt to get these screens working again so they could be transplanted into any future nook color tablets that I might buy on ebay with cracked screens -

Scenario # 1:

since the glass is intact, I was researching ways to separate the non-working digitizer from the LCD part of these screens, and once source said to bake the assembly in a kitchen oven, bake at 280 °C and use a very thin pry tool to separate the LCD part of the assembly from the digitizer part, this told me the lcd is glued to the digitizer, and since i have a 12 temperature settings digital heat gun (Wagner brand from Home Depot), it's 1500 watts/5100 BTU's, and can go from temp setting of 250 °F to 1350 °F, and from my bit of googling, I also found that the LCD's are more pricey than replacement digitizers, but again, I'm not sure if I got a good bargain.

my tablet tool kit

My 12 setting, 12 amp heat gun

and my googling on this topic took me here

where my googling this topic led me

that said, what do you guys think of my purchase/research, etc?

now I have questions:

can I use my new heat gun instead of the kitchen oven to melt the glue holding the broken digitizers to the inside of these NC front panels I bought?

do you guys think I got a good bargain (3 LCD screens once LCD's are separated from the digitizers)?

since I did conversion of heating temp of 280 °C to x°F, I got a temp of 536 °F, I'd have to have my heat gun set to 536 °F, but the gun has as its setting ranges: is lowest temp 250 °F, high 350 °F, the next low/high temp settings are low 450 °F, high 550 °F, and the rest of the settings (low/high) go even higher with the next low temp setting as 650 °F and up, so how am I supposed to do this when I use this gun of these nook color LCD assemblies to melt the glue - what temp should I put it on?

how long should I wave the gun's heat at the LCD assembly?

what sort of motion should I wave the gun in - circular motion or left/right, or top/bottom?

do I need a special timer - (I have a pocket watch with a second sweep hand)?

I also have ipod/ipad pry tools (plastic spudger, guitar pick like tools, one smaller, one larger, a metal pry tool with narrow rounded blade at one end and pointy blade at opposite end) - which tool should I use to separate the glass LCD from the digitizer after using the heat gun to loosen the adhesive?

do you guys think this heat gun was a good investment (I also plan to use it to reflow the ball grid arrays of laptop video chips in future)?

Scenario # 2:

now I'm thinking of leaving these 3 LCD+digi's assembled and forgoing wanting to separate the digi's from the LCD's of these screens, and am now thinking of troubleshooting the non-working digitizers in these LCD assemblies and possibly getting these digitizers to work again.

Has anyone ever had this problem before and successfully repaired their non-working digitizers?

if, so could you show me how to troubleshoot these digi's and possibly get 'em working again?

since I asked this question in 2 forums and still received no replies, I did what I think may be a big mistake: I asked the seller these troubleshooter questions but I think I'm going to regret it later?

this is what I asked the seller:

regarding separating the glass from the digitizers in these screens, I did a bit of googling and an article somewhere said yes it can be done but it's very difficult and the chances of success is very slim, so now I'm thinking to myself, that instead of trying to separate the LCD and the digitizers, why not try to find out why these digitizers in these screens do not work, so may I please ask a few questions pertaining to why these digitizers don't work so that I might try to troubleshoot them and get their digitizers working again -

--when did you notice that these screens stopped responding to touch?

--what happened to the screens (anything odd/unusual) just before you noticed that they no longer responded to touch?

--what did you do (if anything) to try to make them respond to touch after they stopped responding to touch?

could you answer my questions, if you can, since I'm a student computer tech.

the LCD/digi's i bought on ebay are still in box, i haven't even touched them, let alone opened the box.

On the other hand, what if I went with Scenario # 2 and forgo Scenario # 1?

thanks in advance.
