If the LCD was working before replacement, the most likely suspect is a loose cable connection. It is also easy to crimp those tiny flat cables, or to break the locking mechanism so the cable can work its way loose. Sounds like you booted to a black screen after repair, so I would walk back through it and double check every connection, then look at all cables closely in bright light and with a magnifying glass, to be sure nothing sustained damage (twist, crimp, etc.). Remember to check the power cable to the LCD, as well. No power, no backlight, no video.

Is it easy to replace a cracked screen on a acer iconia B1-710?


I've done several Samsungs, a couple of Apples and a Nextbook. I've never done an Acer but I'm guessing it's not too difficult.
Look up YouTube videos on the subject. You can probably find one for the exact device you have.
If the image on your tablet still looks perfect but the glass in front of it is cracked, then you only have to replace the digitizer glass. The screen is behind that. If you have to replace both, try to purchase an assembled package because it will be easier.
Typically, the image screen is fastened to the tablet frame with double-faced tape around the edges. Then another layer of double-faced tape goes around the perimeter of the image screen and the digitizer is stuck onto that. Getting things apart involves using a hair dryer and several little plastic pry tools (some of which look like pry-bars with a handle and some of which look like guitar picks) to separate the glass parts from the heat softened adhesive. I've found that having several single-edge razor blades is also handy as long as you don't slip and push it into your finger.
When you replace the adhesive between the screen glass and the digitizer glass, make sure you don't leave any gaps in the adhesive. Pressing on the front digitizer glass oil-cans it in and out and if you leave any gaps in the adhesive, dust will get sucked in between the sheets of glass.

By the way, I will NEVER do a Nextbook again--at least I wouldn't replace just the glass. They don't use double-faced tape at the factory. The glass was somehow bonded directly to an aluminum frame. Much of the glass I scraped off the frame only came off when pulverized into powder. I would buy the replacement glass already bonded to the aluminum and just snap that on. Probably wouldn't be cheap.

How can you fix a pandigital tablet screen that is cracked?


Sounds like a rough one. Repair the crack? @ things ... Replace the glass and or the screen.You do not want to get any glue or used for that purpose. The glass is to protect the screenso, it would be best to look into replacing the glass. It might be part of the screen itself.
Good Luck-Ned-

What is wrong whith nabi 2 that has sreen probloms


sounds like your screen broke. Nabi has 2 'scereens' a piece of glass on top, then the LCD screen below. The LCD screen can be broken by hitting or twisting it. It can also become more prone to breakage if you leave it out in excessive heat.
Nabi will fix the screen for about $60...

Hi! How do I replace a Viewsonic V1250 tablet pc screen. Mine went completely black with no picture.


If the screen does not have a cracked glass, then it maybe a back-light problem, maybe a faulty inverter or a faulty CCFL lamp. These components are much cheaper to replace than the whole LCD screen.
