    Dynex DX-LCD32-09 had Negative Picture

    Model: DX-LCD32-09
    TV Description: 720p LCD
    Problem: TV shows negative (Inverse) picture

    My TV is showing what looks like a negative. The whole screen seems whitish but when I ran a picture of the TV through a negative filter it looks normal. The power supply is outputing all of the proper voltages.

    My question is could this be the main board or is this an indication of a broken panel?

    What is the Solution?

    I find some website they had same problem & they already replaced the T-Con board on this TV but that didn't do anything, That all I can find maybe they sold the TV

    That's an odd problem, I'm almost tempted to say it's a software/settings problem. Some cameras for example let you select a "negative" filter, maybe for some reason this TV has that option. Try a factory reset from the menu.

            I'm interested in what your problem was as I have a similar problem. Just to understand better what you have said in your posts could you explain two things to me.

            1. Did you actually try swapping the TCON board first to see if the board was faulty or not? I have a 37 inch AU Optronics panel and I am assuming the TCON is replacable like mine.

            2. You swapped the entire LCD panel (including the TCON attached) from the donor TV and the problem was fixed so you believe it was a bad panel?

            I'm hopeful it's the TCON on mine but reading your post is putting some doubt in my mind.

            Also my set is a SANYO but I know both mine and yours are actually manufactured by XECECO.
