I notice there are many DIY out there and gets stuck or end up cracking LCD when just trying to replace cracked glass of HTC Inspire 4G smartphone. So here I am trying to give you help if needed.
Here we have inspire 4G without the backcover. It is pretty simple to remove the back housing.
When disconnecting LCD flex from the board, you need to be very careful not to use metal spudger or anything sharp as there many small capacitors that can easily be broken off the board. Best use your nail and lift up the connector gently upward. DO NOT USE leveraging technique.
Once the top bracket is off, it is time to remove the main board. However the bottom logic board is stuck to LCD frame using adhesive, so heat is required again. Logic board must be pulled in order to keep USB port from breaking off.
In order to replace the glass of HTC Inspire 4G, you must remove LCD from the bracket. This is where many DIY fail as they use too much force to remove the LCD or gets stuck because they don’t realize LCD must be removed. This is not like iPhone 3G or 4 glass repair.
With just enough heat and patience, the LCD with glass is off the frame. Notice where HTC used the tape to stick the LCD to the frame.
Once the glass is off the LCD, notice where the light tube is located. Without this transferred to the new glass, the button on the digitizer will not light up.
With successful transfer of light tube and screen and LCD is sitting correctly, you will notice the tube tip is through the fram in order to transfer the light from the logic board to the digitizer.
