Added some Parts & Repair Services Sites
Remember to research these services on your own before using them.
I came across the following information by researching an answer to a member's post regarding a touchscreen issue.
I wanted to start a separate thread on the topic as it may be easier for others to find this info if needed.
There are alot of Diamond assembly instructions online but not many concentrate on the LCD screen and Digitizer.
Many of us Diamond owners are coming up on a year since we purchased our Diamonds which means that our one year manufacturer's warranty will be up soon. If you don't have insurance, you may find yourself in a position where you will have to look into the following info provided so you can get your Diamond back on the road.
With the screen separation issues that HTC has not resolved yet, many of us may experience screen failures after that one year warranty expires. I have had a screen separation failure that was covered and I also have insurance, but many of us don't.
The following links help provide sites where you can purchase the necessary parts and tools. Some links provide information of where you can access necessary manuals while there are sites that provide detailed assembly instructions.
I have not purchased or used the info from these sites for my own personal assembly and these sites are only posted to be used as references.
I take no responsibility if you use the referenced sites and your Diamond turns into coal

One constant is that if you need to replace either the LCD Screen and/or Digitizer, you should purchase both as a preassembled unit as the installation will be quicker and easier and yield better results.

Take a look at this blog.
While there are online disassembly instructions for the Diamond, not many are specific about the LCD Screen and Digitizer. >>

Appears to involve soldering, etc.
Not as simple as just plug & play.
It appears that you can purchase the LCD & Digitizer preassembled as one unit to avoid alot of extra work and make replacement much easier
