The backlight is LED strips. When the television comes on the power supply senses the current draw and shuts down if it is too high. When one led on the strip burns out the current draw increases. You need to replace the LED strips or troubleshoot down to each diode and find the bad one(s)

Your control board seem's defective or the inverter board (associated circuits) are bad. This is common in most TFT-LCD Tv's.......

SOURCE: tv comes on but no picture

try unplugging the tv (no electricity what so ever going into the tv) and just let it stand vertically for atleat 24-48hours then plug it in and try it out.

if that easy fix doen't work then you either have a blown fuse or and busted lamp. contact a professional and show them your warranty.

SOURCE: My Sharp TV will only hear sound. No picture or images even from the tv menu setup option. Model# LC-19SB25U. About 1.5 yrs old. Converter box ok.

In most cases, you can reset the TV by leaving it unplugged for 30mins.
If this doesn't work, I believe the circuit board that supplies power to the screen maybe bad. They call this board a backlight inverter board. It would most likely cost more to repair than replace the TV .

Do a flashlight test. With the TV on and a program is playing, shine a flashlight on the screen. Can you see movement in the picture? If yes then the backlight drivers are not working. If NOT, then the T-con board is bad You can get parts from here : TV Parts Universal TV Stands DLP Chips ShopJimmy

I have a sharp LC-37D40U that will not power on. The power light blinks 1 time every second. I held the input and volume - button while plugging the TV on and the TV cuts on and then cuts right back off,...

OK if you have blinking red light.

Try to open the cover then disconnect the inverter board after that try to power it on again..

If the light stays in blue (LIT) and of course you don't have picture or backlight you have faulty inverter board that need to be replace.
