That usually indicates power failure some where on the circuite board. If you heard a ' POP" a capacitor probably blew out.

If you knew enough to repair it your self, then you wouldnt be asking and if you dont, then you should take it in for repair by a shop, unless its a cheap t.v., in which case, buy a new one.

You would need to locate what poped and try to obtain a replacement part, then soder it onto the board after removing the bad part.

If you dont know what your doing you could shock or kill yourself, start a fire or damage the T.V. further.

The cost for repair may be as much as buying a new HDTV so be sure you know what its going to cost before dishing out cash to a repair shop.

Good luck

You didn't provide details on what mode you were running or if this worked before and this is a sudden event. The manual doesn't appear to cover this situation of one blinking red light: https://www.lacie.com/download/manual/UM_2big_Quadra_EC_EN.pdf
but I found a YouTube video that may be helpful to you:

Logik wireless mouse


1. Make sure the mouse is fully charged. The underside should have a red flickering light if it is working properly. If not you need to change the batteries.

2. Plug the USB dongle into the computer. The blue light should light up and flash rapidly as you move the mouse around. If it still doesn't work you need to re-sync the mouse with the dongle.

Turn the mouse off and back on again. Hold it near the USB dongle.
Push the blue button on the dongle. It should flash steadily. Push the reset button on the bottom of the mouse. The blue light on the dongle should start flashing rapidly and your mouse should now work.

Suddenly there is no sound in the speaker but headphone works fine..laptop is Lenovo B575


If the head phone jack works its more likely to be the problem, if you use the headphone jack a lot the connections inside it can get worn or bent out of shape--engaging the headphone jack should shut the speakers in the unit off.

Other possible reason is a bad speaker or connections.

Flashing Lights when powered down


The flashing LED is because your system is in "sleep" mode. By default windows Vista puts your computer in sleep. What this means is it doesn't shutdown the power completely it leaves a little going through certain computer components (more specifically the ram) to speed up the boot time when the power button is pressed again.

In XP a the default shutdown scheme is a complete shutdown where power is turned off after the shutdown process is done. If you are using XP you are putting your computer to sleep when shutting down.

As for the boot problem. Newer motherboards have an LED on the actual board to indicate that it is receiving power. If it is of either the power supply switch (at the back of the case) if off or the motherboard connection is loose and the shaking makes it fall into place. (Shaking is usually not necessary and indicates a problem...)

There are a few possibilities I can deduct from your description:
  • the connection from your power supply to your motherboard isn't properly seated and is causing this
  • the power supply switch (not the case switch) is being  turned off and results in the computer taking a few seconds before the internal LED become solid
  • ... the dreaded sign that the power supply is failing and is on it's last legs...
My suggestion is to check all connections and if that doesn't work borrow a power supply from a friend and swap them to see if it boots properly.

(If a friends with a spare power supply isn't an option a local PC repair shop should be able to help you out... but probably for a fee...)

Red Light instead of a Blue one


I've seen this before. The power LED needs to be replaced. If you have the sales receipt, Raidmax will replace it. This won't affect any other part of your PC, so if you don't get it replaced, it's not the end of the world. =)
