Sharp Aquos LC-G5C32U Problem with Green Fuzzy Screen

[tamaneko]

I recently bought this Sharp Aquos LC-G5C32U LCD TV on eBay for cheap, as it had an odd problem with it. I already did a factory reset on it, and it fixed another problem it originally had with having no sound. With the factory reset, the sound is now functioning fine again, however the screen's condition remains unchanged. The screen is appearing fuzzy with green colors everywhere, as pictured here.



However, accessing the TV's built-in menus, as pictured below, shows up clearly without any of the green color problems. However, if the TV is put into an input mode with no connection, the whole screen appears entirely green, yet the built-in TV menu is unaffected.



The same thing shows up on every input available in it, even the TV tuner. What could the problem be for it? Could it be a menu setting somewhere in it that needs to be adjusted? Factory resetting it should've fixed it up though if that was the case. Or could it be a more serious hardware problem that would require taking the TV apart and replacing a specific part in it?
