Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

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. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Black screen delld600


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

Vo42l no picture. please help!


I had the same problem. No picture but sound. When I turned on the tv, and shined a flashlight around the screen from about 3 inches away, I could it was displaying something.

At first I replaced the main board which has 0171-2272-2604 stamped on it. You can google Vizio VO42L service manual and get a pdf which will show how to remove the back. I got the board from TSM www.tristatemodule.com3642-0482-0150 3642-0482-0150 Vizio TV Module, main unit, 0171-2272-2604, 3642-0482-0395, VO42LFHDTV10A 1 $88.95 $88.95

These are compatible replacement inverter boards and work well. All I had to do was bend a tab on the aluminum cover that goes over the boards. After installing these inverter boards the Vizio display works. I started with main board replacement because from what I read online, the problem was either the mainboard (which had the most posts) or the inverter boards. So I picked one.
Install tips:
Download the PDF Service Manual VO42L FHDTV10A_LPL,AUO Service Manual.pdf for some help with the back cover.
When you take all the screws out, set them aside in the same pattern they were on the board for ease of putting the back in.
I was not able to remove the connector on the Ribbon cable between the master and slave invertor, so I left it attached and carefully undid all the tape and removed the boards attached. I plan to send the old boards to Coppell TV (really nice to work with) for their re-use.
I hope this helps.

I just changed the main power board, and everything is fine...apart from no picture...sound is fine. Before the power board died, the picture was fine, apart from what looked like a water damage mark...


You need to try the following:
Check the power supply caps and voltages. Reseat the ribbon cables between the T-CON board (Timing Control board) which drive the LCD panel rows and columns, it get the LVDS (Low Voltage Differential Signals) form the main board which has the VIDEO processor to drive the T-CON board.
When T-CON is dead you will see glowing screen without video, or when it has timing problem you will see lines, rolling, multiple pictures, pixelating.
The main board supplys switched 12vdc to power the T-CON board.
You need to do more checking.
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.
