Does the main lamp light at all? It sounds light a cooling fan failure. If the fan iis not working the the main lamp will not turn on and the power light will flash.

Lights only go on standby


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.

Vizio vw37l hdtv20a standby light on but wont turn on


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.

Luxor tv will not power up and red light just keep flashing


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.

My epson tx700 printer dispaly ink pad at end of life and printer not start


A fix from a forum:

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.

r this one: Switc off your receiver using the main power button on the front face. Hold the the Effect button and the Direct button, and turn the main power ON.f it ain't working, try this one: Turn your receiver ON and, while holding down the [VCR1] button, press the [STANDBY/ON] button. "Clear" might appears on the display and your receiver might enter Standby mode.
Hope it does.. With your receiver in the Standby mode, hold on STRAIGHT (EFFECT) on the front panel and press STANDBY/ON.
* The ADVANCED sETUP menu appears in the front panel display.ress STRAIGHT (EFFECT) to select the desired setting.
RESET = To reset your receiver to its factory presets.
CANCEL = To cancel without making any changes Press STANDBY/ON to confirm your selection.
* If you selected "RESET", your receiver is reset to its factory presets and switches to Standby mode good luck

Start button not working standby light staying


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.
