Question about Projection Televisions
First make sure all the cable at the back of the TV is connected properly.
The problem you referred means that the TV is going in protect mode because it detects an internal problem, try leaving it unplugged for a longer time, let say one hour or two.
Basically, what happens is that the TV does not start because it detects that there is an internal problem, such as a wrong voltage, a bad component, overheating etc.
When you unplug power and restart it, you reset the internal circuit, and the TV will restart, not detecting the internal problem.
As soon as the TV gets hot, after staying on for a while, the defective part start giving troubles, as the defective component (probably an IC, starts overheating).
From description, the digital processing board. can be cause for the problem as there is no video.
However all the following parts can be involved.
Parts involved can be
Polaroid digital processing board.
Polaroid replacement ballast.
Polaroid Replacement LCD controller
Its time to get it repaired.
