[Q] Sensation won't start

So I've got a Sensation phone that won't start. Bootloader menu can't be accessed as well. When I plug it in, the orange LED lights up, stays on for about 3 seconds, then goes off for about a second and finally lights up again and stays on permanently. Tried with a different battery - no luck. When I connect it to the pc via micro usb cable, the computer recognizes the phone (installs drivers for htc sensation). And there's something more - when I connect the charger in a completely dark room, the display backlight becomes visible. The screen doesn't light up but it also doesn't remain completely dark. It's like the screen is on but completely black.
So what can I do? Thought that the power button might be defective, so I removed the black tape over the button and short circuited the two small pins on top of the button. It didn't work. I can't fire it up through abd, because usb debugging is off. So do I have any options beside selling it on ebay or giving to a service technician?

Thanks for the suggestion
I haven't tried this solution yet because the problem does't seem to be a QHSUSB_DLOAD issue.
Upon connection with pc it identifies with hardware id USB\VID_0BB4&PID_0FF9&REV_0228 as a mass storage device...

Dead phone, red charging light & start up screen loop after dropping it

After dropping my XZ on a table, it just went completly dead. The device switched off and wouldn't start again. So I tried to charge it, and hoped for the best, but when I connect it to a charger something strange occurs. The small red charging light comes on, and the black "SONY" text on a white background shows for a few seconds, then the device shuts off and the red light disappears. And from there on it just loops from black screen to red light -> sony logo -> black screen no red light -> red light -> sony logo -> black screen no red light and so on.
I've tried 2 different chargers (for several hours), tried starting it holding vol up and also starting it holding vol down. Tried connecting it to a computer with the xperia companion software, but it doesn't show any signs of connection. The SD card is removed.
I assume it has to be some kind of hardware issue (relating to the drop, yes i was drunk). But does anybody have experience from this problem and might advise what part is broken?
What you actually did with your mobile, step by step.

My honor 4C doesn't charge and the led flashed Red Green Green 3 times but no power

When I connect it to the charger it glows red green green and repeats for 2 times after. If I connect it to the PC and turn it on, the PC makes a connected device sound but still it doesn't turn on. Anyone here knows what it is? Is it bricked?
No clue and found little on a Google search.
If you can easily disconnect the battery, try that.
Better if you can command it to do a hard reboot.
A hard reboot can sometimes resolve issues.
May be a hardware failure.
