Dor, BenQ has a 3yr warranty on their monitors. I would contact their tech support and receive an RMA to return it for repair. It will cost you shipping out there but they will ship it back. I has a BenQ FP731 myself and it blew a capacitor inside that allowed the screen to stay on. Fixed it and had it back in 5-7 days. Good luck.

This is SwannerX and I have solved the problem by locating the DAB radio receiver to a higher position ( some 6ins. higher only ) and orienteering the aerial in an opposite direction.
All 25 stations now tune O.K. and signal quality still reads in the high 90's and signal strength shows 9-10 bars. This is not substantially any more , but it has done the trick!!!
I am still very puzzled why it would not work again in the original position where it has worked well for many years.
Obviously DAB requires a good strong signal as I am living very close to the transmitter at Mounteagle in the Black Isle and the set is upstairs in the house to achieve the highest signal into the set's whip aerial.
Another annoying query I can give you is this :- Every time I do a full AutoTune operation on the DAB receiver , it ALWAYS comes ON tuning BBC Asian 1st. so that station comes up as a 'Favorite' on the Radio's screen. No matter how many other stations I select and listen to for at least 20secs. say, the BBC Asian one STILL is listed as a FAV.
Is this a peculiarity of the Sharp design or a function of the transmission system?
Maybe this BBC Asian is on the first freq. the DAB Radio scans, but I would have thought it would come ON every time with the last station which was selected before it was switched OFF.
What do you think ???

i believe your tv is getting overheated, possibly from dust getting onto the electronic components inside. or the inverter board for the lcd panel inside is going bad, alot of times it is the capacitors on the lcd inverter board going bad.

If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.
