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 flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;

My flat screen tv shuts off and standby led blinks 13 times.


Our $2700 less than 3 year old Sony LCD KDL-40XBR5 did the same thing 2 weeks ago. Sony was anything but helpful. They said to take it to a repair shop or we could send them $550 and they would replace it with a $800 set. Repairman says that it is a panel and the part has been discontinued by Sony. The 46" sets had the same problem and were recalled but not the 40" screen. We stopped on the way home and purchased a 40"

My JVC LT-42X579 42 in. LCD TV is only 13 MONTHS old and it suddenly won't turn on anymore. The blue power light comes on -as usual- but after 3 seconds, it will start blinking and it will remain that way...


I contact JVC and was told to first make sure your cable box or whatever you use to normally watch TV is powered on and is ready to work
He told me to unplug TV for 10 seconds at least. Then he had me press and hold down the "MENU and VOLUME DOWN (-)" buttons, at the same time for about 10 seconds. Then after 10 seconds of holding the 2 buttons down, he had me continue to hold the 2 buttons and press and let go of the power button. In other words after 10 seconds of holding down the volume down (-) and menu buttons, add the third button (power) and immediately let go of all 3 buttons, at the same time.
It worked for me instantlynd hopefully it works for you!!!

TV scrolls through input sources on its own


To make sure the remote is still working, point the remote to the TV sensor, press couple of times and notice the Red LED is response or not. If the LED blinking, the remote works fine. The suspection now is the main board which is control all the inputs. You can try to get TV back to factory reset, it might help.
