SOURCE: I have a 46" Sanyo

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

The problem of your unit is the CCFL - cold cathode fluorescent light. if the both ends of the ccfl is already have a dark spot it must be replace or sometimes the holder of the ccfl is only loosed. Or try to consult a technician for sure, to do some actual test to your unit if you are not familiar in electronic parts and to lessen the stress. Good day and best regards.
