Screen So Bright I Can Barely See Any...

I have a HP Pavilion F1503 Flat Panel Monitor which is just 3 years old, but still in good condition. The problem is the amount of brightness displayed on the screen, I have tried to restart the PC, I have tried to adjust the screen brightness with both the PC panel and the Control Panel but nothing seems to work. I have read the INFORMATION FILE for the monitor but no help is listed on it and the HELP AND SUPPORT section on my PC doesn't have any information for my LCD Monitor... Please send a solution ASAP 'cause I really want my Monitor back to normal...:-)

(By the way, I'm just 12 years old so please use small words for me!! (I've got my parents permission!!))

Cheers, TechMan72!!!
