Troubleshooting procedure for No-Picture is given in detail.
The only way to tell if a backlight (if set has one) is bad is to measure the voltage on the power board and at the back light itself---most voltages are marked on power board or a Service Manual would pinpoint them.
If the voltages are normal and back light is on but DIM only option would be to replace the board that drives it or the actual back lights'
If you Google the model number with "parts" you should be able to locate the back the parts involved.
try to force on the tv un plug and use remote when tv iv completly off. and press display 5 vol+ then power and see if tv stays on and in service menu look for eror code .if tv stays on if it cutts off then one of lamp in screen is defective. its mean screen defective
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. http://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
B+ over current protection (OCP), unit goes to the standby mode then
displays the 2 blink fault. Could be a short in the power
supply of any of the
circuits.
