    I have the same problem and did the diagnosis as described. I am getting constant flashing of power light at 1 sec intervals. No "K" came on but the power did and then shut off again with a "click".



    How difficult/espensive a repair am I in for?

    I had to replace the Main board of the TV, just be sure to get the correct one for your set, take the back cover off and look at the label affixed to the board and google it, I have found the one that I needed on Ebay that worked for me. After replacing the board Voolaa I now have a picture.

The power light is an error code that tells me exactly what is wrong with the TV. Count how many times the POWER led flashes per second? (Dont worry about the OPC led)

1x per second (constant steady blink) = bad inverters/lamps
2x per second = bad power supply
3x per second = bad main board

If its 1x per second, try doing the factory initialization to get the TV back on to confirm a bad lamp/inverter.

Try doing the Factory Initialization (WARNING: THIS GIVES YOU ACCESS TO THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)

  1. unplug tv
  2. press and hold at the same time “Vol –“ and “input” button on the TV set.
  3. while holding those buttons, plug the tv back in
  4. the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go.
Once the TV turns on, take a look at the screen. Does it flicker then shut off? Or do you hear a buzzing noise from the right edge of the TV? If so, then you have bad inverters or lamps. Once youre done, unplug the tv to get it out of the service menu.

If it is 2x per second or 3x per second, then those boards are just bad and they need to be replaced. There isnt anything you can do right now to fix it.

Sharp Aquos TV doesn't work, power light is blinking at 1 blink/sec


Sounds like a fault code, ~I have found some info on it:-

The frequency and color of the blinks will indicate the issue. There is a hold-down button sequence to try to backdoor your way into the set to see if the panel will light. You may have simply racked up too many "weird tuner faults" and need to reset it. My suspicion is that it's either that or bad panel backlight.

Unplug set, press and hold (on set) volume-down and channel-down and hold them while pluging in set. Will come on with "k" on screen, or will crash again if backlight bad. If it stays on, use your remote and arrow right then look for "fact init" and any other reset and turn them on. Arrow back up to "fact init" and hit enter. Let set recycle to green and unplug/re-plug in 5 seconds: the set should be in OOB state.

hope it helps

My Pioneer Receiver VSX-519V has a blinking HDMI light and won't show video.


You guys mentioned the reset via the front panel, and I tried that with this very same issue on my VSX-822-k and it worked!
thought I would post the instructions for anyone else that lands here:
Reset the main unit if the receiver is generally not operating correctly. Switch the receiver into standby mode. Hold down the "BAND" button while pressing the "STANDYBY/ON" button for about two seconds. When "Reset?" appears in the display window, press the "AUTO SURROUND/ STREAM DIRECT" button. "OK?" appears in the display window. Press "STEREO/A.L.C." to confirm. "OK" appears in the window. The system has been reset.

Sharp aquos will not turn on. power opc light flashing


I got a Sharp Aquos Quattron LC-60LE847U, a 60inch LED TV, I only brought it for a year and 4 months, factory only a have one year warranty. Last week when my kid try to turn on the TV, the TV power light keep repeat blinking in 2 slow and 5 fast sequence, don't know what did it mean. When I press the power button, the light will stay on for few seconds and it kept blinking after, the TV cannot turn on at all.
My kid have called the Sharp help line in US, number found in user manual, but the Canada help line are different number, it is 1-877-278-6709, they told my kid to unplug the TV, hold down the Input and the Volume down key, then plug the power back on, the TV can turn into service mode, it have a K icon on the screen, but every time I selected the menu, it went away very quick. Then the customer assistant told my kid to call service.
When I did a lot of research, every solution seems to point to the power supply, so I bought a power supply from ebay, replaced it, it does the same thing, no different at all, then I turn the TV back on in service mode, to try to do a reset from the menu, upgrade the firmware, re-seat all ribbon cables of the main board and the middle logic board (Not sure what is that board call, it is in the middle of the TV), neither way can make any different, the TV light still blinking in same sequence.
So I kept doing the research, I find out another way to reset the TV back to factory setting just by holding down the Volume up and Channel down, then plug in the TV, kept hold it down those 2 buttons until the TV came back on. TV will reset for just by doing this. Happy news, problem seems to get fixed, but not 100 %. The TV seems no problem to turn off and on after reset, but if I unplugged it, the blinking problem will come back, but if I reset it one more time, it will works again until I unplug it again. It is better than completely dead.
Then I unplug the TV, removed all ribbon cables (6 ribbon connectors), use sand paper to clean all the ribbon cable contacts, don't rub it too hard in case the cable contacts get destroy, then re-seat all the ribbon cables. After I did that, everything back to normal and my TV got fixed completely.
This seems to be my way to fix it, not sure everyone can use the same method to fix their blinking power light problem, but I hope this tips can help some people to save big buck to the Sharp service. This TV is over $2000 dollars and I brought few pair of the expensive 3D glasses, I do hope it can last longer, didn't expect it have problem already, it just less than a year and half old and even I bought the power supply to tried to fix it but I ended up didn't needed to spend any money and solved the problem.
Hope this helps.

I have a sharp 32 inch and the green flashes and when i hold down the input and channel down it shows red then i push down the power button hold it goes orange then green it comes on then shuts back off


You don't want to keep doing that because you can make it go into a coma and not turn back on again. It may not work to perform a factory reset INIT (industry initialization) but call sharp aquos 877-322-7867 (87seeaquos) to get a case file created and be walked through an INIT including resetting the lamp errors. If the rep has you read the number of lamp errors and it is not zero then you should be scrolling down and resetting them to zero before changing screens to turn INIT on.

BLINKING POWER LIGHT WON"T RESET


A Blinking Power light on a wrt-54g usually indicates that the firmware is corrupt. You can try to wipe the firmware by following the steps below:

unplug the router
using a paper clip or pin, press the reset button
plug the router back in while the reset button is still pressed down and hold it for 30 seconds.
once you let go of the reset button the router should go through a reset. if it still blinks try the process again.

if the issue still occurs then it may be bricked.

Hi,

You have not mentioned the Canon printer model.

Try this step below.

1. Turn off printer

2. Hold down Resume button and press Power button.

3. Keep holding down Power button and let Resume button go.

4. Press Resume button 2 times then let BOTH buttons go.

5. Green lights will flash and then stop blinking.

6. When green lights are solid, press the Resume button 4 times.

7. Press the Power button and the printer should turn off, if not, press the Power button once more.

Sharp TV LC37D40U Aquos malfunction. It fails to turn on (no picture, no sound) except that power button light blinks off and on continuously. Any ideas. Thanks.


The blinking light is a indicator of a internal failure, it usually blinks as an error code, I have two suggestions, unplug the TV from the power outlet and let it set for at least 30 minutes not plugged into the wall outlet, then plug it back in and see if it has returned to factory defaults and returned to normal operation, if that didn't work then contact sharp @ 1-800-237-4277 and they will gladly assist you. Good luck !

I have a 2008 corolla. It has an auto light when the car needs an oil change. I need to know how to reset it.


Look in your owners manual and go to the part that explains the different symbols on your dash. Look for that service reminder and it should tell you what page to go to to learn more about that. Somewhere there should be some wording to the effect that "When you have your car serviced by a certified Toyota dealer they will reset it for you. In the event that someone other does your maintenance then this is the procedure to reset......."
