Flashing Power Light

The flashing standby light on your Luxor TV can indicate several things, including:

1. Power supply issues: If the TV is not receiving proper power, the standby light will flash.
2. Malfunctioning hardware: A malfunctioning component in the TV such as the power supply, main board, or backlight system can cause the standby light to flash.
3. Overheating: If the TV is overheating, it will go into protection mode and the standby light will flash.
4. Software issues: A software glitch can also cause the TV to display a flashing standby light.

If the flashing standby light persists, it's best to unplug the TV, wait a few minutes, and then plug it back in. If the problem persists, you may need to contact the manufacturer or a professional repair service for further assistance.

The only thing I can tell you is to check the cable if its plugged in correctly... wierd! might be electricity problem to where you moved it. Did you hit it while you were moving it?

"enter and advanced surround keys"? I don't see that documented as a special function in the manual.

BTW: other than the Flashing light, is there a malfunction?

(i) Disconnect all the cables from the TV including the power cable then reconnect them after a few minutes.
(ii) Make sure that the power cord from the TV is directly connected to a functional wall outlet.

If the standby light keeps flashing then service will be required.

Call your Internet Service Provider.
They can remotely "connect" to the cable-modem, and diagnose it.

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.

Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

Unplug the TV for 2 minutes and plug it back on.
It should work.
