SOURCE: toshiba 46H84 tv turned off light 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.

SOURCE: Blinking yellow light ,no picture or sound.

You have done all you can do. If you had a power outage, when the power came back on a it surged and probably caused a Power Supply problem or something in the micro controller to fail. Either way it 's not good. I would call Toshiba and let them guide you to a Service Facility that can check it out. Depending on your Homeowners Insurance, repairs could be coverd or unit be replaced depending on cost to repair.

My polaroid lcd tv, wont turn on, its 16 months old, any ideas?


Try plugging it into another outlet - one which you are certain is working. If that doesn't work, you might have a bad fuse inside your TV. If that isn't it, the power supply board may have failed.

My 46" SONY LED has no sound coming out now.


Hi this sounds very much like a dry or bad solder joint probably on the power supply PCB, if you have the necessary soldering skills and a magnifying glass you maybe able to fix this yourself.

The picture below shows an example of what a dry joint(s) looks like, if you are able to solder and understand the risks in taking apart your TV you could save yourself a good few bucks!

Always make sure the TV is unplugged and please be aware that voltages can still be stored even when the tv is turned off, if in any doubt or you are unsure about attempting a repair please consult a qualified TV technician.

Hope this helps

Led lights flashing


replace the lamp. the lamps basicly have 3000 hours before they go, and also depends on the number of times the unit is turned on and off which greatly lessens the life of the lamp.
