Have 19" Technika flat screen TV.Cannot get picture.Sound is ok.What could be the problem?

Had this same problem, more than likely it is your Backlight Inverter. If you turn out the lights in your room to make it as dark as possible and then turn on the tv and hold a flashlight really close to the screen at a slight angle, if you can see movement it is definitely your backlight inverter. These can usually be found on line and are relatively inexpensive and easy to replace. You can usually find a video on Youtube that will walk you thru the process. I did mine on my 50' RCA in about 7 minutes, and most of that time was removing the screws from the back of the tv. Good Luck

Sound no picture.

This is most probably your backlight inverter. Easiest way to know for sure is to turn off the lights and make it rather dark in your room, next turn on tv, then place a flashlight at an angle close to the screen. If you see a slight movement in the screen from what ever is being played then it is simply your inverter. These are relatively inexpensive and found online, also you can find tutorials on Youtube that ill walk you thru replacement. My 50" RCA took me 7 minutes to replace. Good Luck

I have sound but no picture on my tv

This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.

Sony bravia kdl46bx450 has sound but no picture

Sounds like you have a backlight problem. I would suggest turning on the set, dimming the lights in the room. Take a bright flashlight and shine it on the screen, do you see a faint picture?

JVC LT-52P789 no picture just sound

If this is an LCD TV, show a flash light on the screen from a safe distance. If you can see picture, it means the backlights have gone off and the TV might need servicing.

What is opc that pops up about every 10 Min

OPC is optical picture control. The television is adjusting itself to the lighting in the room. Even if someone walks in front of the television's sensor it will start to adjust and you will see opc on the screen and green leaves.
You can leave the feature on without the opc and green leaves appearing on the screen. Press the menu button. Scroll down to OPC. Press enter. Scroll to on. Press enter. Press menu to exit.

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.
