The red light is blinking on my akaiDVD player

The red power light blinking could indicate either a fault in the power supply board or the LHB953 has kicked in auto-protect. Unplug all connections to the player. To properly reset the device, unplug the player, then hold down the power button for 35 seconds. Then plug the device back in and see if the blinking still occurs.

The On/off button of my LG LCD does not turn on the tv and the red/green light of the power indicator doesn't light up, but when plugging in the power cable to the outlet the on/off button light is...

your TV has a power supply issue or a logic fault.
Don't try and fix this yourself as the power supplies in these TV sets are extremely dangerous !!
These TV's can only be fixed to board level which means this repair may get expensive.
My advice would be to take the TV to a professional or have them call to your home to check it out..

Power box light is blinking orange and sometime a steady red and console want come on.

Green Indicator Light:

The default indicator light is green. When the Xbox 360 power supply light is green it means that there are no problems with your power supply. However, if you are having problems and the power supply light is green, this means that the console is faulty and you need to contact Xbox 360 support.

Orange or Yellow Indicator Light

When the Xbox 360 power supply light is orange or yellow this means there is no problem with your console but the power supply can't supply it with power.

To remedy this problem, first try unplugging the Xbox 360 power supply from the console and unplug the power cord from the wall outlet. You'll also want to uplug the Xbox 360 power supply from the power cord.

Wait for about five minutes and then reconnect everything. You might also want to try plugging it into another wall outlet without an extension cord.

If you are still getting an orange or yellow indicator light, then something is at fault with the Xbox 360 power supply. If this is the case, contact the Xbox 360 customer support to get a new one.

Red Indicator Light:

If the xbox 360 power supply light is red, then there is something wrong with the power supply connection. If this is the case, try the same solution as listed above of unplugging the power supply from the console, unplugging the power cord from the wall outlet and unplugging the power supply from the power cord. Wait for about five minutes and then reconnect everything. You might also want to try plugging it into another wall outlet without an extension cord.

If the indicator lights are still red, then there is a fault with the power supply. If this is the case, contact customer support about getting a new one.

No Indicator Light:

If the XBox 360 power supply light is not illuminating at all, this usually means that the Xbox power supply is not connected to the wall outlet correctly. On the other hand, it might also be a fault with the power supply or the power cord.

Either way, try the same solution as listed above for the red indicator lights. If you still don't see any lights illuminated after unplugging and then reconnecting everything, you'll need to contact customer support about getting a new power supply.

Green and Orange Indicator Light:

If the indicator light is flashing green and orange, this may mean that the console does not detect the AV Pack.

Disconnect and then reconnect the Xbox AV Pack. Make sure the connections are firmly connected. Turn your Xbox back on.

If the indicator light is still flashing green and orange, try another AV pack if one is available.

If the indicator light is still flashing green and orange, you'll need to contact Miscrosoft Customer support.

Flashing Orange Indicator Light:

If your Xbox console's indicator light flashes orange, this means the internal components have overheated and the Xbox has automatically shut down to prevent damage.

Turn off the console and let it cool for at least 10 minutes.

To prevent the Xbox from overheating in the future, make sure that it's not placed in a closed cabinet or on carpet. It's best to get the Xbox elevated off the ground where the PSU can have maximum heat release.

You'll also want to make sure the Xbox is not located near a heat source like the back side of a television, computer, monitor, or other electrical device.

When I power on the tv, the light goes to green and then a few seconds later goes to a red flashing light

When a set is powered up, there are internal checks that are performed. The initial green light indicates that power has been applied. The flashing red light indicates that a problem was found that is preventing the set from functioning properly and it has shutdown to prevent further damaeg. If you can supply the model number, I may be able to provide additional details. Also, check to see if the flashing red light has a pattern. Quite often the pattern will indicate what problem was detected.

Thanks,
Dan

Hitachi 55VG825 rear proj television blinking light and screen doesn't light up

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...
