Flashing Red Power Light

check for a bad lamp then make sure the fan is working.

A continuous flashing red light with the word LAMP on it would definitely mean you're going to need to spend a few bucks on a new lamp....or for a few more, upgrade to a TV from this century that doesn't require lamp changes :)

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.

The repetitive blinking light is a trouble code which is used to determine which series of boards may need to be replaced. How many times does the red light blink?

Here's an excerpt from the Sony Manual online. And the link - http://esupport.sony.com/US/perl/webtree.pl?template=EN&mdl=KDF55XS955&content_id=68&category_id=11&problem_id=52

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.

if the status light is flashing .5 seconds on and 2.5 seconds off - you need to replace the lamp cover correctly.
if the status light is flashing .5 seconds on and .5 seconds off in 2 - 6 cycles the error is: 2 cycles - the projector is overheated. Move the projector to a cooler location, or/and remove dust in the light path. 3 cycles - the power unit is not working correctly. 4 cycles - the fans are not working correctly 5 cycles - lamp fails to light. Wait a full minute and then turn on again.

Same problem with my Sony. Unplugging for 36 hours solved the problem

If the red light flashes at plug in you likely have a main board that is bad. If you have to press the power button before the red light flashes you likely have a bad bad supply board. This will need to be diagnosed by a technician to be sure of the problem.

I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.

You need to get the ballast repair kit #LSUC0002 and replace the parts to your ballast.

I have the exact same TV, did the above this past weekend, and the TV works like new.

You need to know how to solder though. It's not that hard.
