Power and OPC light blinking. TV doesn't turn on.


These 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.

TV won't turn on


the first thing that you need to do is to open the back cover of your tv.Go to the power supply section it is separate board where the power cord is connected.Using a multitester,plug in the power cord and measure for the output supply.see if the 5vdc ,12vdc and 24vdc are present..if one of this output is missing,replace the power supply board But if the output voltage are complete,replace the inverter board,It is a board that supplies the high voltage to the backlights of your monitor/screen....You can also try to reset the system of your tv by pressing the the small switch mounted on the main board press it twice while the power is on...tnx and good luck!

Tv shutting off


How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

You can buy the parts online and fix if yourself!!

How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
