Question about Insignia IS-LCDTV32 32 in. Television
I am referring to
I explained what a 'bust' capacitor is..it will have a swollen top. And for your information, the blow dryer trick DOES work, depending on the actual issue. See here:
I also advised the user to replace the power board FIRST. But if he wanted, he could replace the faulty capacitor(s). And oh yes, only an idiot would think he can just pull the capacitors out without desoldering first. If you dont know this much, then you shouldnt attempt it, eh?
So next time you want to criticize, make sure you have your facts in place, before ending up looking the fool.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

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.
