I have a type 6734-LB1 17" Lenovo ThinkVision

Search google or youtube

I do not know how many Thinkvision models are out there, but here is a site that offers manuals you can read online or download.
This is just a page from the manual I found. Here is a link to the manual I found. http://www.manualslib.com/manual/91948/Lenovo-Thinkvision-E54.html#manual
THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF
THERE IS NO VIDEO INPUT SIGNAL. IN ORDER FOR THIS
MONITOR TO OPERATE PROPERLY, THERE MUST BE A VIDEO
INPUT SIGNAL.
This feature is designed to conserve electrical energy by reducing power
consumption when there is no video input signal present.when there is no
video input signal present.When there is no video input signal, this monitor,
following a time-out period,will automatically switch to an OFF mode. And the
LED will turn orange. This reduces the monitor's internal power supply
consumption. After the video input signal is restored, full power is restored
and the display is automatically redrawn. The appearance is similar to a
"Screen Saver" feature except the display is completely off. The display is
restored by pressing a key on the keyboard, or clicking the mouse. Lenovo ThinkVision E54 User Manual

You may need to blow the dust out of the back of the monitor or get a new rebuilt monitor. They run about $30 at shops that rebuild them. Usually good will stores have computer stores attached to some of them. The computer store in Omaha is Called good bytes.

you need to use other utility software to format then only install.
But your recovery parttition will gone.
Never able to restore back to win8

Sounds to me your high voltage powersupply is out. To repair open monitor and remove high voltage powersupply. Inspect the caps on the board. Look for the ends of the caps to be mushroomed out. Replace these caps, usally 470 uf caps. Replace with 25volt caps. Might also be some 100uf caps as well. This is a common problem with all LCD monitors.

The inverter module is bad or the back light behind the LCD screen has stopped working, I would suggest an estimate if you decide to have it repaired.

Some wide-screen monitors have a "rotate" option in the software that comes with the monitor -- you physically rotate the screen 90 degrees, and then Windows will rotate the entire "desktop" so that you now have an "extra-tall' screen, instead of an "extra-wide" screen.

you would have to get a 64bit compatable processor for you machine. and some times upgrading a laptop processor is almost as much as a new machine.
