    I think it flashes 3 or 4 short and 1 long (sorry not at home at the moment) but only on the monitor.

    different model - same problem. Won't turn on, red power light on tv flashes.

    Same problem. One day no picture. One long, four short red flashes from the power light on the TV. Sharpe's customer service web site ignores my email. I'll never buy a Sharp product ever again.

The condition of your TV called power supply overcurrent shutdown that"s why you hear a click. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating . Although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....

Hope this may help you..

SOURCE: Sharp LC-26D43U Power light flashes and unit won't turn on?

It's a power supply related problem. When it turns itself off, this it called protection mode. The TV automatically turns off to protect other parts form being damaged.
The most common problem is the Power Supply Unit or the Backlight Inverter Board.
You may have to take the TV to a repair shop to find out which one is bad. Paying a repair shop to replace the board for you maybe more than the TV is worth. If you let them diagnose it and you replace the bad circuit board yourself, it would be cheaper.

Here's a place I use to get parts for TVs:

The problem is the repair shop may charge you double or three times of what the part costs at the web site link above. Then, plus labor. I just want to save you money. :)

SOURCE: sharp lc-22sv6u won,t power on. no green light.

Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

Hi,

Try unplugging the TV from the power point and leave unplugged for 5 min.
Or the batteries in the remote may be flat, try replacing the batteries.
If this doesn't work the TV may have a fault.

I hope this helps

My sharp aquos LC-60E79U has no picture. Perhaps I have a backlight problem?


. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Sharp model lc-20sh1u won't turn on, just makes a clicking sound and indicator light flashes red.


The clicking sound may be a power relay coming on and then off--problem indicates a trouble in the main power supply.

Denon AVR-1908 won't power on


Are you getting a standby light at all? Is it flashing? Do you here a click when you plug the unit in? If the answer is no to all of these then you blew a fuse. If you do have soome sort of standby light, then your set is in protect mode. More than likely for a blown channel. If no lights, but you ar egetting a click, you could have a bad transformer. Use a DVM and see if it is open or not. Good luck

This is not a split system a/c unit guys. Look at the picture. The blinking light means the air filter may need cleaning. Reset power to turn it off.

Won't power up


Hi, The owners manual says that if the red light is flashing, it is an indicator that it is ready to be turned on (use remote or onboard on button); flashing red & green - too high temperature inside, the unit is overheated. Check and clean the air filters; If the red light is steady, abnormal condition and you have to call for service. A copy of your manual is available at http://www.eiki.com/resources/resourcedownload.ashx?filename=/ownersmanuals/om_xb25_20_sb20.pdf Hope this be of some help. Pls post again how things turn up. good luck and kind regards.
