Sounds like AFT, AGC voltages are not proper. Contact any service technician. The main board of your TV has to be troubleshooted.
If the main system control memory IC is bad, this kind of fault can occur. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC.
