20 Most Recent Sharp AQUOS LC60LE847U 60 inch 1080p Quattron Technology 3D LED L Questions & Answers

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.

Check for a bad power supply in set.

Question edited for a lot more clarity! All questions need full 'make model (what it is)' please.Question moved to Sharp Aquos category.This is their support page which is pretty bad. There is an email link. You don't say WHY you want a firmware update, but firmware in not supplied for televisions according to our Fixya television expert Larry. Firmware updating is fraught with danger and should not be undertaken lightly even when it is available. Sharp only supply software updates, no firmware.https://www.sharpusa.com/Support/ProductDetail.aspx?model=LC-60E78UNSOFTWARE updates are here in the manual on this page and continues in detail on the next page.https://www.manualslib.com/manual/318507/Sharp-Aquos-Lc-60e78un.html?page=24..

Go to Menu select function or Service and checked auto demo is on. If it is on make it OFF

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/ Blinking codes details to many popular brand TVs are given.

No, you just told the television to format the USB into its own formatting format. It doesn't back it up for you. You should have purposely made a back up of everything on the USB memory stick to your computer. If you haven't done that, you can put the USB stick into the computer and use 'Undelete' software. Recuva is pretty good and the ones that normally say 'Free', mean they are free to see what is can find, but not to restore is back. https://www.google.com/search?q=%27Undelete%27+software Recuva https://www.ccleaner.com/recuva Everyone should have CCleaner! ..

im not sure but could it be a comparability issue with the device and the wake up signal from the device to the tv? android systems use a Linux based file system, so the problem may be in the tv's input settings. hdmi input from the device to the tv. and then go to tv input mode and see if putting the device in another hdmi port doesn't work.
