Those blinks are error codes. Count the number of blinks and go on line with the make and model no. of the TV and number of blinks. For example (Sony Trinitron 46xxxxxxx 4 flash error code ). This will tell you whats wrong with the TV.

For some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Check the voltages going to the TV main board first. If they are all good, replace the main TV board. That;s where the problem is.

There's a weak capacitor on the power board. Look for a bulged or leaky capacitor and replace it.
