I've had this tv for about 6 or seven years at first this problem was intermittent. Now it's permanent. I have a Bell sat pvr and a dvd player. This problem is present no matter what unit I use

Thanks for the info, this kind of problem related to backlight system, either the lamps in particular area inside screen are not producing enough bright light and causing the darker image OR the lamps are not getting sufficient volts from inverter board thus producing low light as compare to other lamps inside screen.

I'm afraid the only test is to replace backlight inverter board in TV to see if it fix the issue or entire screen/ display panel will be replaced which isn't economical because it would cost more than new 32 inch TV.

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV. Please feel free to respond if you have any additional questions.
