Some possibly useful information here, I'm going to save this page, try a few and see how it goes. Many thanks to all the posters. :-)

One more idea
After a couple of years of normal operation, I moved my Aquos from the bedroom to the office, and it started the brightness flickering. Reset all the menu options, no luck. It also had 60hz ground loop bands rolling up the screen.
Installed an inline Cable Isolator w/ Spike Protection, problem solved. $12.25 delivered in the US,
The discovery is that apparently the flickering can be caused by a 60 hz ground loop, and the isolater fixed both problems.

just played around with it and figured it out:
- Select your Backlight settings (mines at 16, brightest) and turn OPC ON! I REPEAT, OPC ON.
next, go to
>>>Advanced (still under picture tab)
>>>Range of OPC
----Turn both tabs as far to the RIGHT (making it brighter) as you possibly can. This should fix everything!

Try going to the advanced menu and switch off the active contrast control. that should help alot

Looked at page 37 of the operation manual. Think this feature is called "enhanced picture contrast". Depending on the AV mode selected, feature is on or off. Selecting movie, game, pc, user will turn this feature off. OPC looks at the light in your room. By the way, with opc on, my cable remote control won t let me change channels due to interferences!!! Weird....

Had the exact same issue.
How stupid is that?? darkening dark scene and brightening light ones, it probably makes contrast ratings go higher but the viewer can't see anything!
Anyway, the solution should be to put the av mode to "user". In this mode, opc is disabled by default, and it is actually enforced, whereas in other modes it is always on.

I used to have the same brightness problem. I have Bell Express Vu (Hi-Def) and would replay the same piece of recorded video to see if the issue always happened at the same spot. It wouldn't. It doesn't seem tied to the video source.
It seems I no longer have this problem as the screen now just goes to black. The power is still on. I get nothing from the other video source I have connected either. I also tried to pull up the menu since it shouldn't require a video source at all. Still nothing. This problem is intermittent as well. Sometimes it's only out for a few seconds, sometimes for minutes.

DO NOT BUY ANY SHARP TV

Hi, My Sharp LCD tv also has the same problems you are experiencing. A sharp technician was able to minimize the brightness problems (but not eliminate it) by accessing the service menu on the TV. As your local Sharp tech if he can do the same for you.

There in NO OPC Solution, No tech nor Sharp will be abel to do anything. Any one who bought Sharp TV, expect very poor service and no solution to OPC problems on any size SHARP. Face it folks Sharp sucks!!! SONY is the best bang for your buck.
