Sharp 68 inch tv will not turn on

Our 4 year old Sharp 68 in tv stopped working in the middle of a program. It will not turn back on.  It was making a humming sound which someone told us it was the color wheel, but now it is completely dead, you can hear it try to start, ,but then the power button and the lamp button just start blinking back and forth can you tell us what the problem may be?

If the tv has never had a lamp put in it, that is the first place I would go. You can refernce your owner's mainual to find the exact location, but usually the lamp has easy access so that you can check it quickly. If the lamp is OK, the ballast is probably an issue. I hope this helps. Check you lamp first

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.

4 year old vizio 42 inch tv lcd. While watching tv, the screen started dimming. There is a 4 inch shadow all along left side of the screen and the 1 inch line shadow going down the middle of the screen.


Maybe a power supply or related issue but at 4 years of age the set has reached its life span----parts will be hard or impossible to find.

If you got four years I would retire it and recycle it and then replace it.

I had the same issue with my Sharp Aquos 52 inch LCD TV. I called Sharp. The tech had me unplug my TV, take the batteries out of the remote (TV remote not cable) and press all buttons on the remote (including the buttons under the flip top at the bottom of the remote). I did this, put the batteries back in and plugged in the tv and everything worked. I had gone 4 months having to use the surround sound for volume and turning the TV on and off by hand. This took 2 minutes to fix.

My 32-inch lcd tv from sharp has no picture but audio works fine. No picture ever comes up, not even the "please wait" message. Whats going on?


My 3 year old Sharp LC-40C32U would start up fine but within a minute would go dark (audio continued fine). For a while I could turn the set off and on again and it would be fine, but over time this became less effective. My solution, which has worked for a week now, was to a) unplug the set's power cord; b) after 3 minutes plug it back in and turn the set on; c) on the remote hit MENU and slide over to SETUP (3 clicks to the right if the screen is dark) and one up to RESET; d) hit ENTER and follow the prompts. This puts the set in it's factory configuration so you will have to rescan for channels. Worked for me.

My new Sharp tv only displays in monochrome


It should work. You may want to try DVD player or play a VCR tape to be sure that it is the TV. If it is the TV and it is brand new from a retailer, I would take it back for a exchange.
If they will not exchange it, get in touch with Sharp and find a local Servicer that will repair it
under warrenty.
I hope this helps,

No sound on Sharp Aquos 37' LC-37D4U


When I first bought my Sharp Aquos 42 inch TV...I started having sound problems...turned the volume way up to 60 maximum and could hardly hear it.
Then after the TV was on for 4 or 5 hours, there would be crackling chirping popping noise. It seems after the TV heats up for awhile...there is MAJOR sound problems.
So I was advised to buy a Sony surround system and connect it to my TV...deactivate the TV volume and use ONLY the surround sound. I did that...but the surround audio cables are connected to the back of the TV and I get the exact SAME problem with chirping and crackling sounds after the TV heats up.
SHARP IS NOT BEING HONEST WITH CUSTOMERS.
There should definitely be a RECALL on the sound board.
Replacing it does nothing....the overheating of the TV just damages the new sound board and the TV has to be repaired again and again.
