Ns LCD 26-09 TV not powering up

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

The six blinks should have been the G1 board, double check your wiring and the check to make sure you have the 17V coming from the G1 board. If the problem has not changed it is possible you got a bad board.

Problem is related with Back light error. Check 24V DC from power board to inverter board. if ok then Inverter board or LCD Panel needs to be replace.

Are you certain the replacement power supply is good? A defective main board or power supply can cause this problem.

you have a faulty parts inside..try to disconnect one by one the supply of all board until you get stable lights..

I have this model of the sharp tv.Happen to me very often the Power and OPC LED light indicators blink continueosly.Not the power supply board,it the Tuner board that take in the comming broscast signal that have the problems.You still can used this tv.Push the power button sometime the tv it will work right away.Not,each time POWER and OPC lights continueosly blinks.Just push the power button again each time the POWER and the OPC continueosly blinks.Just have push power button again about 4 times each time Power and OPC blinks recycles,it will finally show the backlight and picture come on.My guest,if u do this by pushing power button to recycles about 10-12 times each time the POWER and OPC blinks it time to change the Tuner signal board.

sounds like u have a bad mainboard.

Hi,
6 times blink shows problem with back light inverter board.
TV requires back light inverter board replacement. If you have electronics repair experience and want to repair TV by yourself, let me know to guide you part purchase.

Insignia is Best Buy's store brand which is an LG tv. The power supply board needs to be tested to see if all the voltages it produces are present. If they are, then look at replacing the main board.

I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
