If it is a bluish colour then the organic polarizer plate that allows the blue light to pass through it to the blue lcd panel is burnt due to old age.
If the spot is made up of pixel shaped spots rather than a blurred area, then perhaps the lcd panel is faulty, but this is less frequently the case.
You could disconnect the power cable and remove the cover and look at the optics parts to check where any overheated parts can be found.
Then you can be certain which bits to replace.
Another option is to buy a faulty VT590 unit off ebay for a fraction of the price and have a go at swapping the parts between the units.
The lcd panels can be removed and replaced, but require precision alignment and you need the extender cables to be able to do it successfully. So give that a miss, replace the whole lcd prism assembly as one item.
Hope this helps.

It is not the smartboard, lamp or the computer as well know, it's the projector itself. This may not work but you at least need to try press the auto adjust button on the projector and then adjust the clock/phase in the menu. If not you will need to send in to NEC it could by the color wheel. Usually they have a warranty for a couple of years.

LCD VGA Display goes on and off.


Check refresh rate and setting for external display output. It won't work with unsuitable screen resolution, color depth or refresh rate. Check all three points and I believe you can troubleshoot the problem this way.

Nec projector vt590 doesn't project RED


Red, Green, and Blue signals come from different wires in the VGA cable.  This sometimes happens if a cable simply is not connected fully.  But it will also happen if the cable is damaged.  The damage might be visible in the form of a bent, broken, or missing pin.  Or it might be internal to the cable.
Try another cable.
If that's not it, then the connector on either your computer or on the projector itself might be damaged.
Also try another computer.
Components inside the projector could also fail.  But I'd bet on a cable problem any day.
