A:Answer Touch screens if damaged will most likely have to be replaced. The price would vary depending on type of device and model, etc.. If you can't repair/replace this yourself, you have to ask BestBuy or manufacturer, if still under warranty or not, or some other repair shop, how much it would cost for a replacement.
If your able to do this yourself, then you need to find out the part number and do a search on the internet for it. Check with the manufacturer for this information, using model number, service tag number, etc. to find it.
Hope this helps...
