The Backlights inverter, the T-CON,or the 24vdc power supply may have gone out, it will require in-depth troubleshooting. Please read below:
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

if you do not have the directions. first manually turn on the set. then i find the code button. it may not say the same thing but it will be similar in words. push code, then push tv, then repeatedly push power until the set goes off then find enter(or something similar). this is an automatic code find technique.

You're better off just replacing the TV because of cost. If it is still under warranty why not contact the dealer you bought it from for an authorized service center location.

that television model doesn't exist. It only exists in Fixya with people asking about it.


You need a new remote. You can't run a television WITHOUT a remote. They are all available online, on Amazon, on eBay or here

This happens because of the color decoder in the TV. A TV color decoder has a switch that makes the TV image black and white when the received signal does not have sufficient power. Your TV color decoder switch remains in the black and white position (the TV receives weak signal or the TV color decoder is damaged).

Replace the TV antenna, try an antenna amplifier or a digital receiver before the TV.

Most power conversion devices contains coils, such as transformers or inductors. These components use electromagnetism to convert AC main power to low-voltage DC power. The varying magnetic fields generated by these components can cause them to physically vibrate at high frequency, resulting in a high-pitched noise.
