Replacing LCD screen on Toshiba Satellite Radius P55W.

Today I’ll be replacing failed LCD screen assembly on a Toshiba Satellite Radius P55W laptop. I’m replacing the screen because of failed digitizer. The touch screen started showing bubbles and registering phantom touches on the screen.

In Toshiba Satellite Radius P55W laptop the LCD screen permanently attached (glued) to the digitizer. If either of them failed, the entire LCD assembly has to be replaced.

I’ve seen some eBay sellers offering touch screen digitizers separately but I really doubt you can replace it and make look factory perfect again. I tried separating the LCD screen and digitizer just to find out if it’s possible and the experiment failed completely.

It’s a good idea to disconnect the battery before taking apart the display assembly. I explained how to access the battery in this Toshiba Satellite Radius P55W disassembly guide.
