Possible that this is a protection shut down that show up. The processor does not switch the main +B as there are errors in the main board. So remove power plug and look for possible visible damage on the board for leaked capacitors.
if so there is short on the board and so there is no feedback to the processor and so is shut down. use a multimeter to check for shorts in circuit.

There are a number of reasons as to why the IC is not working. Is there a power supply fault and it's not getting power, has it got dry joints, has a component failed in the circuit or is the IC faulty and most important, why did it fail!

I have an old Thomson TV 21FDR more than 10 years old. Recently the Tv screen has a lot of disturbances with the screen full of hirizontal lines and a hissing sound. A well trained technican had replaced the tuner with a new one . But after some 2-3 days the same problem is with the tv. Kindly help me with suggestions.

Sostituire la 24Wc08P con una nuova. Substitute 24WC08P with a new one. In this model it's very stressed and since it's a flash memory it has a limited number of writes. Ciao

Try searching the net for your tv's service mode on how to enter or access it.

Your tv could have one of several faults. None of which are to be tackled by anyone except a qualified engineer due to the electric shock hazard.the first problem could be the crt (tube) the second could be the componets on crt base circuit board ie resistors or ic.
With a tv 9 years old it may not be economical to carry out a reair.
