Facing TV Problems? Ask a TV Technician.
Hello and sorry you're having problems.
That means your Color Wheel in the Toshiba (which is a DLP that uses a wheel that spins at high velocity to produce the color) has shattered and requires replacement.
There are no pushbutton fixes for that, as it's a hardware failure. That being said, to have this done at a shop you're looking at around $300 parts and labor and a shop can be located at the link below:
Alternatively if this is something you're looking to replace yourself, the color wheel can be purchased below for $100 and there are YouTube videos out there that show it's replacement, but keep in mind the TV must be disassembled to access the color wheel:
Other than that, I'm sorry for the bad news and wish there were a quick fix.
