SOURCE: TV won't turn on with
The flashing timer light blinks out a code, where it flashes some number of times, pauses, then repeats. The code indicates what fault is keeping the set from coming on. Unfortunately, all the codes tend to mean that there is some electronic problem with the TV. Unless you have some electronic servicing skills and the necessary equipment to troubleshoot the problem, you'll need to have set checked by a professional. For any code there can be many causes, so I can't offer any other advice.
This might be a good time to check sale prices on LCD sets. Let a technician check the set and give an estimate for the repair, then decide.
SOURCE: won't turn on, standby light flashes then
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 multi-meter 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.
