My tv is stuck rotating from a "red, blue, and green" screen and I had a tech come out and he said that it appears to be stuck in factory "test mode." His recommendation is that either the board needs to be replaced or that entering a particular combination on the remote (code) might be able to pull the tv out of "test mode." Does anyone know if this sounds accurate and if so where I could find these codes to try and pull the tv out of test mode?

Thanks

Unplug the tv overnight,you cant put this tv in service mode with remote.If unplugging it doesnt work,you need a scaler board,

I actually took the advice of the local repairman and replaced the mainboard myself and the tv still behaves exactly the same. so obviously, its not the main board. sorry, i did this before seeing the reply about the scalar board. just to clarify, the scalar board is just a different board? replacing the main board was pretty simple - just unscrew and replace, reconnect all the grounds and cables. should replacing the scalar board be this simple? also i assume that all lcd tvs have scalar board?

thanks
