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. :)

Acer as3810t no display


OK, best thing to do is test the external video port with a desktop monitor. The laptop will have a Fn key (function) commonly blue in color. The display icon in conjunction with the Fn key will switch between the 2 displays. Common issues with laptop displays is the back light inside the LCD display of the laptop. Power on laptop in a dark room and sometimes you can see the display, just slightly.
If you can see it, replay or have somebody replay the back light in the display. Was This Helpful? Yes OR No *Please vote yes if this helped you

Hi Ansari
It sounds like a main board problem. The control voltage that goes to back-light inverter board; from the main board, goes down. Contact any service technician. This is not a user repairable fault. Gopakumar Gopalan Google

Check and replace the back light inverter board. It is faulty. If you're sound in electronics, and wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

Backlight burned out, how do I replace it?


The back light is typically an integral part of the LCD display, so you may have to replace the entire display. On some displays, the touchscreen and back light connections are separate from the display and on some displays, these connections are soldered to the LCD display. Trying to take apart the LCD display just to change the back light can result in breaking the LCD display. You are better off just replacing the entire display if you can find it for that model.
