An all too common problem with lcd's, you would think they would be more reliable after being on the market for years, alas they are not. See if it does the same thing on a friends PC if you are able; if so the you will know the lcd is faulty.

Resolder the power transistors on inverter board and also check them.If display is not there at all some of this 4 transistors C5707 should be defective.Check associated fuse and Fet which drives the transistor.
Also check with Benq ,Normally offers three year warranty.

Yeah, for most of you it's definitely the caps. The three that are 470uF and the one 330uF.
Don’t just replace them with new ones of the same type, they will just blow again. Use ones with a higher voltage rating. you can also use ones with slightly higher uF (they are just output caps for the SMPS). Mine are at like ~530uF and its holding strong.
If your having trouble with brightness there is a jumper that lets you change the amount of power going to the cold cathode bulbs. It is right next to the three bigger caps. it has three settings, 6.5mA, 7mA, and 7.5mA. it should be set to 6.5mA by default. The bigger numbers are brighter, but remember to crank your brightness all the way down before changing this jumper as 6.5mA with maxed out user brightness is the same thing as 7mA all the way down.
These are good monitors as far as stats and usability. They just have defective parts. I was amassed with how "defined" the picture is per-pixel considering it's VGA.

Power off the television. Wait a few minutes, then power it back on. If this does not correct the issue leave the power on, point your remote control towards the Sony television and hold the down arrow button. While holding the down arrow button press the "Power" button. Release the down arrow button and the Sony TV will reset itself to factory settings. Once the television performs a scan on itself your problem should be gone.
Good Luck Ed Pinero
