SOURCE: Insignia NS-32LCD Backlight or Inverter bad???

If you've done the flash light test, it could be the inverter board became defective but it could also be that the power supply does not provide the +24VDC to the back light inverter board.
If you could do the +24VDC test using a voltmeter then we can say for sure that the back light inverter board is defective.
Let me know if you need further assistance.

My Samsung tv turns on but has no sound or picture ... how do i fix that


Some Samsung tv's have a common fault of capacitors breaking down.
Especially the 32" flat screen model.
If you are not happy changing components your self send for an expert.
However, you may look up Samsung TV repairs on Youtube, there are several step by step tutorials there.

Replace it with a new LCD Inverter, you can address the following issues:
Screen image, but the power light stays in
Dark display, but still readable
Flashing on and off of the screen between 1/2 to several seconds
The power indicator stays on, but no display and sound
Screen images, but LCD TV still has sound
Picture cycle on and off, as well as high-power LED lights

Tv picture went out


Look closely at the screen, use a flash light right against it and see if the screen is on but not being illuminated. If you can see something on the screen then the issue is the back light. If the back light is not coming on, the first thing to check is the inverter.

Turn on my 50" samsung plasma i have sound but no


Hello, this usually means that a cable or something is not plugged in properly.
Maybe you just put in the audio cable and no cable which can transmit video?
If it's a HDMI cable make sure it's plugged in properly and that you're on the right channel.

Faint or no picture on olevia / syntax tv model LT-37HVS


When you tune to a station and get sound I presume the screen is black so do the following.
Place a bright flashlight against the screen. Look for an image around the edge of the flashlight.
If you see an image the problem is probably one of three causes.

1) Power to the inverter board is bad.
2) Inverter board has failed.
3) The CCFT(cold cathode fluorescent light) are dead.

Someone knowledgeable in electronics can diagnosis it.

TV was playing, then the screen turned black.


If the screen is black and you have sound then lightly press and shine a strong flashlight against the screen. If you see an image around the edge of the flashlight, an image is being 'displayed'. The problem is probably in the Inverter/CCFT or the power going to the Inverter.
