Question about Televison & Video
What is the model number of the TV? Chances are, if it's a newer model, it's integrated into the T-CON (timing controller) board.

I had the same problem. Mine gave out in 4 months. Those boards are hard to find right now. Google the the board# BA71FOFO1042 and someone like (buyjimmy.com) I think will sell TV parts. If not, you can fix the board itself like I did. Mine was a bad inverter transformer. If you need the parts# for anything let me know, I have the Service Manual for the TV. Good Luck

The most common cause of sound and no picture problems is the power supply inverter board. There are parts called capacitors that overheat and fail. If you can do a little soldering then you should be able to repair the board yourself. Here is a link to a repair kit with the proper capacitors for that board.

Several things can cause your Dell Latittude D600 laptop's LCD screen to stop working.
Two of the most common causes relate directly to the inverter board and the backlight lamp.
The inverter board is a thin circuit board placed inside the LCD panel.
It's main function is to transfer power from the motherboard to the backlight bulb inside the LCD screen.
If the inverter board goes bad or the backlight lamp burns out, the screen will appear dim or eventually go completely black.
Turn off the laptop, unplug the power cable, close the LCD panel and place the laptop face down.
Remove the battery pack from its compartment on the bottom of the computer.
Flip the laptop back over and reopen the display panel all the way until it is in a 180-degree position.
Insert a flat head screwdriver into the right side of the keyboard bezel.
This is the plastic strip situated above the top row of keyboard keys. Carefully pry the bezel from the laptop.
Remove the two Phillips screws located above the top row of keyboard keys.
Grasp the top edge of the keyboard, tilt it upward and lay the keyboard face down on the palm rest area.
Unplug the keyboard's ribbon cable from the motherboard connector.
Carefully remove the entire keyboard from the laptop.
Disconnect the video and speaker cables extending from either side of the LCD panel to the motherboard.
Loosen the Phillips head screws on each LCD panel hinge.
Carefully lift the entire LCD panel off the laptop's base.
Relocate the panel to a flat work surface, and place the panel so the screen is facing upward.
Use a thin, flat head screwdriver to pry the rubber screw covers from the LCD panel's front plastic cover.
Remove the Phillips head screws revealed by the rubber covers.
Carefully remove the front plastic cover from the display panel.
Locate the inverter board situated below the LCD screen, inside the bottom edge of the display panel.
Disconnect the two cables from each end of the inverter.
Remove the two Phillips head screws fastening the inverter to the display panel.
Carefully lift the inverter board out of the display panel, and dispose of it.
Repeat this procedure in reverse to install the new inverter board, and reassemble the laptop.
Hope this helps
