I have a lc320slx sylvania tv and I pushed some button, but now it keeps flashing different colors on the screen. It flashes red, green, blue, white, etc. The remote won't control the tv and the only way to turn it off is to unplug it. I saw that someone else had the same problem with a diff tv. Something about a "diagnostic colour test" the solution that seemed to work was holding menu and enter and then pressing power. (heres the link http://www.fixya.com/support/t115143-tv_just_flashes_different_colors) My remote does not have a menu button so what do I do????

Is it still the tuner board if i pushed some buttons first and then it started to do that. It didn't just happen randomly. I pushed a selection of buttons first and it turned to channel 1 and started doing that. The other people say that repairmen told them their tvs were broke too, but it was really in some crazy mode that they had to get out of. Though they had a different tv, the tvs were doing the exact same thing as mine... a red screen would pop up for a couple of seconds, then another, then another....
