You probably have some sort of overheating or short on the internal board - is it still on warranty? if so they will fix at no charge - if not, a local repair shop should be able to correct the problem but it may cost as much as $150

Jvc tv power light keep blinking but tv wont turn on model av 27720

Its power regulator section circuit ahs the fault. If you want to repair this section, you must have through knoledge in electronics and work experience. Most of the components in this section are very dangerous to touch. It is fatal for an unexpereinced one to try to repair this section.
If you are confident, download the repair manual to your set from internet and follow.

JVC AV-36D502: Input #3 doesn't work

Good day sir, its a different issue, about the capacitor, for as long as your replacement part is correct, it will work, now, there are several things you should check, the I/O device that controls the inputs of the TV, usually an IC, check your schematic diagram to trace the fault. check also the line from the input 3 to the controller IC on your diagram. Measure the voltage across the IC Vcc to ground if the IC is getting the right power, Low voltage can be cause by faulty capacitors, on the power supply line, or the IC itself is faulty, Circuit analysis and voltage measurements are needed to trace the faulty part. hope this helps thanks.

TV turned off itself and timer light (red) keeps blinking

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.

If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
