Flashing of power LED are fault indications. You have to count the number of flashes occurs at one time. Check this link for more details about the blinking codes. Do a search by entering the brand name to your device by its search box at top right of the display window, because, posts are not arranged in alphabetical order, but by brand name first.

I gather it is a JVC, do we know here the exact model number as it is not clear here, Models with AV are conventional regular TV sets but there are hundreds of different ones.

Power supply board is dead.U have a LED light indicator on LCD panel flashing?The tv is completely dead,no LED light at all?Tries Website like Shopjimmy.com.Ebay.com to buy a refurbish power supply for the replacement.

U know how to solder right?Take the backcover off take back of the handle screw driver taps where the part said it flickker or video back on, resolder that.

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.

Hello, I am a tv tech. I worked on a JVC AV-32D502 today. Problem: led flashes / no power or picture at all. Same as trobertson52's set. The microprocessor is bad in my machine. trobertson52, if your sets' relay does not click when the power button is depressed you most likely have the same problem or the standby power circuit is at fault. That circuit supplies +5 volts to the micro.

Edtal you have a different problem with your machine. Your machine is going into shutdown. A number of circuits could cause this and would need to be looked at by a technician to determine exactly which circuit is at fault. High voltage transformer (HOT) \ Vertical Circuit \ Power supply are the most likely causes.

When your set first turns on it runs a systems check to see if the boards inside are safe to apply voltage to. also it checks the power supply to see if it is safe to power up.
Either it needs a factory reset which the procedure changes for each model. or it simply has more wrong with it after the surge and requires more to fix it then the cost of a new set.
The best bet is to look on EBAY for a similar set with something like a broken screen. swap out your screen into its chassis. 
if you do not feel up to the challenge of doing that you may be looking at repair costs and parts that are more then a new set.

there is another problem that requires a tv repairmans expertise when the timer light flashes continuosly ,and the power is not restored.

From our experience, ther may be a power supply failure, or one of the scan circuits have failed. The fault can be one of many possiblities.

The set will need shop service.
