Are power board issues common with HW55ES?
I have had my HW55ES projector for a little over a year, since 11/2015. I'm a little concerned with the quality of my unit.
One thing is - the fan has always sounded a little grumbly, not very smooth, and not as quiet as the showroom unit. Always have wondered if my fan wasn't the best quality.
Second thing is - I have tried three bulbs - all OEM bulbs, and none of them have been able to go past 30 hrs or so without developing flicker issues. So I have had to run them on high power.
Now, on one of the bulbs I'm at 660 hours, and I'm getting bulb flicker at high power as well, intermittent, sometimes bad, sometimes not so bad. It's actually worst when on the blue screen with no inputs active. Then it is really very noticeable.
I'm going to get out one of the other bulbs and see how long it lasts... but if it starts going at 500-600 hours, I'll be demanding warranty service.
I suspect the power board or power regulation is not very good on this unit, and it's quite disappointing.
Does anyone know if this (power regulation, flickering bulbs) is a common issue with these HW55ES units?
