Your TVs system memory IC has damaged. System memory IC is one which stores all the data we give to the TV externally. This IC is a small one which have 8 solder terminals, and very cheap to buy. Can be located very near to the main system control IC. All the data we gives, and the data that has processed by the main system IC, that is brightness, contrast, colour etc:- are stored in different memory locations of this IC, and wiil be retrived back to the system control IC, as and when requred and preocessed by the system control and given to chroma and other section of the IC as we switch on the TV every time. Although this is a Small one and cheap to buy, its function in the circuit is typical. In fact this IC controls the all other functions of the TV.
Replacing it will solve the problem of your tV. It is very important to note the number of this IC. The number will be printed on it, and should be noted when buying a new one. Insist on same number, and not replace it with equivalents. The set won't even switch ON if you replace it with other numbers. It can be bough from most of the electronic soare part shops at your town. OK.
