Query: Panasonix AX-100U sucks + no support

I had purchased this projector12 months back and am facing a problem as briefed below and possible solutions tried but the problem is still not fixed.1) The projector powers off after 30-60 seconds on starting and goes on stand by (yellow light). It then shows a red light of power off2) The projector does not start after this with the remote3) It has to be powered off from the mains and then restarted4) Earlier, this used to happen once and now it behaves abnormally and sometimes it has to be restarted even upto 8 times or sometimes even just 2 times5) After this, the projector does not shut down and movies can be watched for even as long as 8-10 hoursThe projector was given to a service centre who did not find any problems in the hardware (power ballast, fans, bulb etc is ok). They have suggested that the PCB mainboard should be changed which costs as much as a new projector.
