Blue light flashes 4 times but no power

Blue light flashes 4 times when you plug it in. It turns off, kicks itself back on and flashes 4 times again. This process repeats itself I'm sure is something wrong with the power board but I need advice to replace capacitors.

Orange light flashing, no chargine


A replacement battery must be the EXACT same power spec as the original in DC volts and Milliamps, or you could damage the Mobo components. Some aftermarket batteries do not work well. The connections may be different.

How many times does the light flash... i.e. flash flash flash flash flash...pause, then repeats?


If you include the make and model of the TV in your reply this would be helpful.

What does theblue light mean when its blinking


the steady, blinking blue light means it is working. If the light blinks quickly, ususally 3 times, then it is either turning itself off or turning itself on. if you're getting a steady blink, try holding the button down long enough for it to flash rapidly 3 times in succession. after that, it should blink no more, because you have just turned it off. Want to turn it back on? hold the same button down until it flashes rapidly 3 times again, and you have just turned it back on.

Error Code: Blue light flashes 4 times


Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, something simple like a blown fuse inside the TV. The most common board to go bad is the Backlight Inverter Board. It what supplies power to the screen. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

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.

Insignia 42 inch TV won't turn on


The power supply is in the protect mode. There are many things in the set that can cuase this. Most likely there is a short on one of the circuit boards, or the power supply itself has failed.

You will have to have the set serviced in order to get it going again.
