Brightness control I bought a the Sharp Aquos 42 inch from Sears in March. I noticed that the brightness would flicker from dark to light (back and forth)during a night scene. It's bad enought that it makes me dizzy and when it's dark I can't see anything. Sears tried to repair the set but couldn't, and then replaced it with the same model. The second set is doing the same thing. I called Sharp and they sent me an authorized repairman. He took the TV into the shop and the next day I was informed that unfortunately that's how this model is and there is nothing they can do. I can't accept this form a $2,000 TV. They said that's from the brightnesss control which unfortunately can't be turned off. When I turn on the OPC feature the screeen just goes dark and dull. The technician from Sears and from Sharp agreed thet the picture was too dark and they both saw it flicker from dark to light and back to dark (over and over), yet they said that no one else has complained. I find this hard to believe. Is there anyone else out there with this problem? I know it's not just me--my family, friends, and 2 technicians saw the problem. If someone out there has a solution--great. Otherwise I have to start fighting with Sharp and Sears on Monday. I wish I bought a Samsung.

I bought Sharp Aquos 52" in Costco. Picture is great, but night scenes are too dark, sometimes completely black and the screen is flickering up and down. I haven't complained yet thinking it can be adjusted, but it seems I can't do anything. Any advice?

I have the same issue - they said to disable the OPC function (menu- picture - OPC on/off) but i think i've tried that and it hasn't helped.

i get a headache trying to see low-light scenes.

I bought a 42" but the 43u version and I'm having the same problem. It even flicker when changing channels.

I love the TV and I don't want to be forced to return it. Help. I bought a 42" but the 43u version and I'm having the same problem. It even flicker when changing channels.

• OPC = Off -> dims in and out.
  


• OPC = On -> almost too dark to watch.

i had the same problem but the technician did not accept it, and said it is normal. i regret why i didnot buy a sony X model. i had the same problem but the technician did not accept it, and said it is normal. i regret why i didnot buy a sony X model.

I have the same problem when the channel is changed and the set goes form a bright to dark background. the entire picture darkens during a scene with dark background and the lightens when the background goes to a bright background. During the credits for a movie the screen darkens greatly. Sharp sent a tech to install software that was supposed to fix the problem. It did not. The tech called sharp and sharp suggested that we turn on the opc. With the opc on the TV is fine but you must adjust the contrast and sharpness. I bought the TV at Sam's Club for $868.00 last November as a one day special. I will purchase Sharps extended warrenty for 3 years. My 40" Sony works perfectly. I doubt that I'll buy another Sharp

We have the same annoying 'dark-light' issue posted. Frustrating. I did call the service people soon after purchasing, waited 35 minutes on hold/music and did not get anyone to really assist me with the problem. We tried the OPC on/off but to no avail. We thought it was part of a problem with a new DVD player we purchased at about the same time. We recently purchased another component and in the process of reconnecting everything, decided to try again to figure it out. WE DID IT!!!!!!

The OPC does need to be OFF. And then the brightness adjusted as well. Not eve sure what else we did but it can be fixed. Sharp should have done a better job.
