    Thanks and I will try that as part of another suggestion to unp;lug the unit from the mains for an hour or so. When I plug it back in I will put it directly into the mains.

    Wonderful. It is now working. Cannot thank you enough.

  • rcdavies42 Sep 10, 2009

    You are a genius. It now works. Cannot thank you enough.

    Have you tried bypassing the surge protector by plugging tv directly into power point as your power board may of failed after the surge/power cut.

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.

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.

The tv went into self protect mode. It is not good enough just to turn it off for a few minutes. You need to re4move the plug from the circuit and leave off for up to two hours. It then reset itself and the problem was fixed. A complication was that the surge protection board also needed to reset itself. This was achieved by the same method.

We had bad weather lights went out ..had tv plugged into a power surge plug ...now that i have power back tv wont come on


Some will say a surge protector will save electronics. I can tell you they may not help at all. A power surge is extremely fast and can over ride the surge protector. If you think you can repair this TV, I would certainly remove the back cover and inspect. Occasionally the only problem for repair is to replace the main fuse. Remember, this happens rarely. Most cases after a surge the TV will need to be inspected by a TV tech. Almost anything, in a power surge will damage the TV. There is no certain area that will not be damaged, expect it any where. Thanks for asking and show all hands of support!

Went to turn on tv no power- no power light!! only 3years old.


Check your power connection and the cable going into the TV. Also, if it is plugged into a surge protector, test to make sure the surge protector is working and that it hasn't tripped. If it is getting power, but it still refuses to turn on, take it to a tv repair shop for repairs.

I have a Mitsubishi projection model WS-B55 that is plugged into a surge protector. The power went off for about an hour or an hour and a half this morning, and the power light is flashing. I called...


First, to answer your last question, not all power outages and subsequent surges are created equally nor are all surge protectors. Also, after a power outage where the subsequent surge is so strong that it got past your surge protector and knocks out your TV and it's never done that before... REPLACE YOUR SURGE PROTECTOR.
However, that being said, in my experience it is unlikely that the TV is going to require a technician. Understand that the person that you spoke with in tech Support is not a technician and is reading off of a list of troubleshooting pages that are more extensive then what's in the manual. What the technician is probably not aware of is that your TV, like most home electronics, has a safety failsafe that requires the device to be separated from power completely before doing a system reset
First, after pressing the button it's supposed to flash for about a minute anyway but I'm assuming that after it's done pressing that the TV is still not firing up.
Unplug the TV, let it sit for an hour, plug it back in (to the wall, not the suspect surge protector). If the light is still flashing, press the reset button again and wait for it to stop flashing and attempt to turn it on again. If it doesn't work, unplug the TV, follow the same steps however, let it sit for 24 hours before plugging it back in. That length of time is not common but some sets do require it.
If none of this works, then I would say that it's time to call a technician.

Tv does not turn on after a thunderstorm and several attempts at power returning to the home. The power went on briefly then shut off several times, now the television will not turn on. We had the tv...


Check the main fuse in the power supply, the TV also has small surge protection devices (MOVs) installed after the fuse, any surges the come along and big enough will cause the main AC fuse to blow. When you surge protector, EVERY connections must go through the surge protector, for example, the AC cord of the TV is connected to the surge protector, the cable connection did not go through the surge protection, the surge then can get to the TV through the cables.

Power surge hit my surge protector with my 'sony tv hooked to it.


Well, the power supply may be still damaged by the surge, what may happen is that when first surge happens the surge protector protect your TV by sacrifing itself but then the second surge comes along, since the protector already blown up then the surge will just come right through to the TV on the second surge. That is bad problem for the surge protector that sacrify itself but can only do it for ONE time.

No power either!!


Unplug the surge protector and plug the tv in directly to an outlet that you know is working, plug something else in first to be sure.

you may find that your surge protector is shot. if it is toss it and get a new one.

Does my samsung tv keeping turning itself off because of not having plugged it into a surge protector or is it more a fault with my tv


It is a fault with your power supply module actually inside the tv...take it to a local service center or if its under warranty take it back. surge protectors help prevent issues like this occuring due to damage to the power supply from surges but not having one wont cause these problems unless it has recieved a surge.....in future i would use a surge protector on all your expensive appliances, surges and power fluctuations are very common in mains power i live near the mines and we have power problems all the time!! hope this helps,ben
