Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

We were watching our TV and suddenly the picture went out. We still have sound. This is true with any device hooked to the TV as well....sound but no picture.

You must contact a svc co. This is a upper or lower buffer board problem and possibly a control board. Nothing you have done wrong, it just happened.

Vertical lines showing up after being on for awhile


Eh, I can't be too sure, but it sounds like it's either a heat issue, a signal issue, or a backlight issue. Either way, if it's still under warranty I'd send it in.

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.
