I just bought a sharp tv lc32sb24u as an open box so it did not come with a manual. i have a blue display box that pops up that i don't know how to get rid of and is there anyway that i can change the brightness on the tv because on some channels it is way to bright and on others not bright enough. when i go to the options it says that this option is not allowed.

SOURCE: T.V. won't allow me to adjust color and sound...

Chepe_77,

You are absolutely correct. The reason why you cannot change your audio and video settings are due to the fact that you are in "Dynamic Fixed". Which is one of your many av modes. Av modes are different preset color settings and dynamic fixed is the only one that will lock your settings. Best Buy set it that way so that people could not just come by and alter the settings on the unit. AV modes are on all sharp lcd products and even though you have the wrong remote you should have an av mode button on the remote that came with it. Try pressing the av mode button and see what happens. When you press the av mode button, you will see your av modes change at the bottom of the screen. However, the issue still remains that you have the wrong remote. So there is a chance that you may press the av mode button on the remote that you have, but it still will may not work ONLY because you have the wrong remote. If the remote you have does not work, I GUARANTEE that pressing the av mode button on the proper remote will take care of that. If you dont want to purchase the remote from sharp, www.partstore.com is a good place. Good luck to you

SOURCE: the picture looks bright blue

The only adjustment that would mess up the color of the image is the tint: it should be at 0, in the middle. If it's already there then the defect is in the image processor or the connections between the main board (the board on which the image processor is glued upon) and the t-con board. To identify which you must open the tv and reseat every single cable there. If no improvement is observed you will have to replace the main board at a cost of $145.
If you don't know how to do that then it will be better to take the tv to a repair shop: the connectors for the cables are fragile and they can be easily damaged if you don't disengage them the correct way.

SOURCE: I have a Sharp LC 40D78UN LCD TV. The brightness

In this tv the brightness of the screen is actually generated separately, by a set of CCFL / neon tubes. These tubes are powered by an special board, the inverter / ballast one. If the brightness oscillated it means that the high tension generated by the ballast for the neon tubes oscillates - an indication that either the board is faulty or something has gone wrong with the power source of the tv - it cannot longer deliver the necessary power to the ballast board.
To find out what is wrong the voltages in the power source and ballast board must be checked, the faulty board identified and replaced. That requires a good knowledge of electronics, you will probably have to call a repairman.
Or you could just replace the boards and hope it fixes it (like they do in most shops anyway)
