Only power light will power on for few seconds then flashes.

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.

How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC.

you either have a faulty power supply or faulty main board. Vizio power supplies on the older sets are pretty decent. It's usually the main boards that go. These older main boards tend to be pricey so it may be better to buy a new set.

Continuous blinks of standby light indicates a fault in the IIC data bus. The main board is likely to be faulty. If you wish to know more Check this link.

I just pull out the mains plug for a few seconds then put it back in. The red light keeps flasing for a while (be patient) then stays solid red. When I then switch on again with the remote it is fine. I often have to do this.

Depending on what type of printer you have:

Procedure 1 We found this procedure to work for the Stylus Photo 1270 type printer, and understand that it also works for the 870 range and even earlier models like the Stylus Color 740. The error is indicated on these printers by all four lights on the printer flashing. Even if you press the power switch on the printer, the lights continue to flash, and the printer does not turn off!

1. Turn off your printer, ensuring that the print head is at it's home location and locked in place as normal;
2. Power off the printer at the wall or by removing the power cable, for at least 20 seconds;
3. When you restore power to the printer at the wall socket or by reinserting the cable, if the lights come back on straight away, the printer's power switch was 'on' - switch it off and return to step 1;
4. Hold down the paper-feed button and the button with the ink-drops next to it, and then turn on the printer, still holding the buttons down;
5. When the paper-out LED flashes, release the buttons;
6. Press and hold the Cleaning button, until several lights flash - this will take a few seconds (i.e. then release the button);
7. The printer will now attempt to reset, including resetting the EEPROM memory and running a short (about 10 seconds) cleaning cycle.

Procedure 2

1. Turn off your printer, ensuring that the print head is at it's home location and locked in place as normal;
2. Hold down the paper feed button only;
3. Turn on the printer;
4. As the paper feed light starts flashing, release the button;
5. Immediately hold down the ink-drops button for some 10-20 seconds or until the printer springs into life;
6. Allow printer to complete it's processing, then turn off for a few seconds, and back on again for a newly working printer!

Procedure 3 - for 1290 and possibly 890 printers 1290 printer with green (power / data) and red (ink / paper feed) lights flashing alternately:

1. Switch off printer with panel switch;
2. Switch off printer at mains switch - leave off for 20+ seconds;
3. Hold down roll feed and sheet feed buttons;
4. Switch on at mains;
5. Switch on at printer panel;
6. Continue to hold down roll and sheet feed buttons until both green and red lights flash together in synchronisation, not alternately;
7. Switch printer off and then, after a few seconds, on again at mains switch;
8. When red and green lights are both flashing in synchronisation, release the roll and sheet feed buttons;
9. Press and hold down the ROLL FEED button (the one at the extreme left) and keep it down until the machine finishes whirring, cleaning etc and the green light comes on steady;
10. Release the roll feed button and all should be well.

"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?

Page 72 describes how it REALLY resets...

Resetting the main unit

Use this procedure to reset all the receiver's settings to the factory default. Use the front

panel controls to do this.

1 Switch the receiver into standby.

2 While holding down the TONE button, press and hold the STANDBY/ON button for about three seconds.

3 When you see RESET? appear in the display, press ENTER .

OK? shows in the display.

4 Press SYSTEM SETUP to confirm.

OK appears in the display to indicate that the receiver has been reset to the factory default
settings.

replaced the lamp

The switch is for 'REC' 'Standby' and "PLAY".
If you leave it switched to "Play" and pull the plug and push it in to the wall receptacle (mains) it should start playing after a few seconds delay. The same for "REC". You use a timer unit on the power cord for those.
If you have the switch in the middle position and plugged-in, you should have a tiny Red LED illuminated. Push "Power" and it should start-up and be ready to use in a matter of a few seconds.

I think that its some problem with your main board.so it is better to call your dealers
