Yes, keep your 1006.1.

As a workaround, you might try a HDMI switch-box to funnel your sources into a working port (HDMI3 ?) All but the dirt cheap ones are IR remote controllable.

I would try : Service Mode -> Option Byte -> LED life

Not possible electronically, its determined by the mechanics of the DMD / lens / mirror design.
