Nook HD+ booting into a blank screen and stays like that [help]

[mashac]

Yesterday I put it on charging when I went to sleep. Today morning I tried to ON the tab and it just boots to a blank screen and stays like that. My Nook HD+ has stock rom and only modifications was one which allow third pary apps to install. I don't know what to do, please help me...

[Edit] It won't even boot to the CWM backup SD card. When long press power button screen's truning off and long pressing power button again makes the blank screen to appear. Once it reached till the nook 99% screen and then it became blank, twice the very first nook boot screen appeared and then it went blank... and now after several trying only blank screen appears.

After a lot of tries, it finally resetted to factory settings. But a couple of minutes after loging in to my account, blank black screen again appeared and it stays like that. I turned the device off and turned it on after some time, it again booted to the black blank screen for a couple of times. I decided to leave the device on like that. After about 5-7 minutes staying idle, the device booted to the nook os automatically. But the blank screen process repeated. I tried restoring my stock backup using CWM, but the blank screen process is happening in CWM too after some time.... After a lot of tries, I finally restored my stock backup using CWM. But the problem is still there.... Anybody know what is happening? What I do now?

Any advice is really appreciated... thanks.

It sounds like a defective device to me. Time for a warranty exchange.
