To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Tv has picture for 3 seconds then goes blank. Sound is good.I was told that the backlight or inverter boards were bad so I replaced both of them still not working.Can someone please offer some help.


There is a flat cable coming from the bottom of the screen and ends in a circuit board usually under a metal cover. This board is the problem. You can get a replacement at:

Hello
Check the backlight inverter board to your TV. This is a common fault for most of the LCD TVs. If it is faulty, the backlight won't light up, resulting a balck screen with sound.

Screen "Flashes" on/off


You could have a faulty CCFL lamp or inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
