That is, a beautiful AMOLED LCD on this Dinc is cracked. Phone itself vibrated and lighted its buttons -- after I charged the battery. With $26.59 LCD screen replacement purchase 5 days later I'm ready to tackle the repair. There's plenty of more or less detailed instruction videos available, as Dinc was one of the most popular phone in its time. Watching these gives you some ideas.
Contrary to what videos tell you, the LCD panel can be replaced with couple ribbons sitting still in their connectors. But I pulled them all out anyway: a good picture of Dinc's internals is rare these days.
Assembly went without a hitch except for I didn't notice the tab on optical trackpad connector remained up (not flattened), like it was originally:
So, trackpad didn't work at the first attempt: tab was up. After the culprit was found and tab was flattened, everything started to work like a charm:
Extra $15 could buy me a new glass/digitizer, as my original Dinc shows some tiny dings. But for a $10 I spent originally on this dead phone it would be an overkill.
Next step: unlocking, rooting, flashing Jelly Bean. It's a pity there's no "official" Cyanogen Mod 10.1 project for HTC Droid Incredible and no 3.0.x kernel for it. The phone running stock Android 2.3.4 is relatively fast and smooth, and the reason going for Jelly Bean is adding better HWA in video decoding/rendering, better camera (8 MPix stock cam is probably the worst among other 8 megapixels), plus some of that JB "butter". Android 4.2.2 ROMs available are all work in progress in these respects. Or is there a good ROM?
