Your TV is stuck in "Purity Check Mode." In that mode, the TV cycles through full-screen displays of red, green, blue, white, and partial-white to check for non-active pixels.

This indicates that the TV somehow went into service mode, and the colors on your screen are a test pattern.
Color flash
The first, is to try and reset the EPROM in the TV. To do this, remove the power cord from the wall, then press and hold the power button on the TV itself (not the remote) for 20 seconds. Then plug the set back in and power it up.
The next thing we can try on a user level, is to use the TV remote, and press Cursor Arrows UP then Down, and unplug power. Then plug it back in.
If this does not cure the issue, then this indicates a failure in the TV's EPROM which is what runs this Test/Service Mode, and there are no resets or adjustments you can perform to fix this.
Also try just pressing exit on remote--

Reset- Symptom---Buttons on TV don't work and screen flashes different colors one at a time...red, blue, white, green, black
Try this--Stand near the TV's power cord and on the TV's remote press first the arrow up then arrow down and unplug the TV within 5 seconds , wait 10 seconds and try the TV again.
If that does not do it then, repeat the procedure but this time with the arrows left then right.
Test Mode

Press "EXIT"

My proscan tv did the flashing color on the screen and the way i got it back to normal was by pressing the stand by button on the tv waited 5 seconds and pressed it again and as it was turning on pressed the menu and source buttons on the tv simultaneously and when the tv was on it was on the menu. I turned the tv off with the remote turned it back on and was back to normal. Hope it helps someone.

Hey everybody! I had this problem on my Speler brand flatscreen while programming a universal cable remote. All I had to do was hit the “exit” button on the tv’s remote and I got out of it! Problem solved!
