    I was thinking if I follow my 120 volt plug into the back of my LCD—I thought this is or would be where the inverter would be. I know what a connector is I am talking of the actual entire board. Please explain and thanks for the help.

    Just a note I have 3 sections of boards in the back of my LCD—1-- Where my 120volt power feed, 2-middle of screen, and then 1 more. Which are you speaking of the middle board—any scene shot?

    Yes it has helped-- I appreciate this--Do you know where I might fine one for the best price?

No, that is just the connector. The inverter board is inside the LCD on an elongated printed circuit board. Its input would be pure DC as opposed to AC from the 120 mains. Its function is to produce high frequency/high voltage to supply the Cold Cathode Florescent Lamp(s) which provide the backlight illumination of the LCD panel.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    Hi again,

    My compliments that you have gone as far as checking the inside of the monitor.

    Chances are the board where the 120 leads to would be the power supply board.

    Most inverters are elongated printed circuit boards with small transformers for the high freq/high voltage. Below are images of inverters.

    To my understanding, a most Gateway models uses either an LG708G or an LG708K. The inverter itself was manufactured by Ambit with part# 6633TZA013A.

    Hope this be of additional help.

Screen wil not hook up to tower, have Dell tower, there is not button to puch, is this a wireless, or is the button hidden. I just got it, and have not idea how to use it, when it is not obviousl Please...

Monitors are not wireless devices. What model of Westinghouse monitor is it? I can check my stack of manuals for a specific location for the power button.

General setup for connecting a monitor to a computer:

With the computer and the monitor off, first make sure that the monitor power and data cables (VGA for example) are securely connected to the monitor. Plug the data cable into the corresponding port on the back of the computer. Make sure to use the active video port (if you have a video card, use those ports and not the ones on the motherboard). Plug the power cable into a good electrical outlet. Turn on the monitor with the power button on the lower right hand side of the monitor as you look at the front of the unit (I'm using the LTV-19W3 for one possible location of the power button). (Some other monitors will have the power button on the top or under the bezel at the front of the unit.). If the monitor has several source options, press the Input or Source button to set the monitor to the one that matches the cable currently in use.

Now turn on the computer. (Please note that if the monitor is turned on after the computer, the computer may not properly identify the resolution. You should see something on the screen, even if it is a No Signal message.) Do you get an image on the screen? (I've found on some new computers with multiple video ports available, only one is active when the computer is delivered. You have to use a monitor with the cable for the active port to switch to another port (and changing cables).)

Trouble-shooting guidelines:

Next thing is to check if the monitor is good. Did a light come on indicating that the monitor had power (or was in standby)? If there is no power indications, then the power supply or the power cord has failed (try another power cord - listed as a CPU/monitor power cord at most shops). Then try a new data cable. Check if the monitor works on another computer if you can. The next items that can fail are the backlights, backlight inverter or video board itself.

It's probably a backlight or backlight inverter issue if the problem occurs on all sources and the onscreen menus. (The backlight itself usually fades or makes the on-screen image change to pink/red.) With a bad backlight, you'll usually see a very dim image if you look at the monitor from an inch from the screen. Block the room light from overwhelming this image (sometimes a carefully positioned flashlight will help you see something). If the inverter or video board is bad, you will see nothing. For an out-of-warranty monitor, open up the back of the monitor and remove the shielding. Look for any scorch marks or bulging or damaged capacitors. (Sometimes other parts will fail on this part but these can be spotted easily. Capacitors look like cylinders on a tripod.) The scorch mark and smoke may indicate a resistor or zener diode that had been used as a fuse and is now gone.

If you borrow (or have a) high-end multimeter (able to measure high frequencies - 50 kHz) or an oscilloscope, hold the multimeter probes a fraction of an inch apart about an inch above the inverter board and power up the TV. If you see a 1 or an actual value, you have a good inverter. If you see a reading near 0, the board is bad or the multimeter can't resolve the frequency.

In either case, you can buy a replacement inverter for $50-150 and just do a simple swap. Disconnect all of the wires (connections are similar to molex and ribbon cables in a computer) and remove board (a few screws usually). Connect the cables to the new inverter. (If you google backlight inverter replacement, you'll find videos and text descriptions.) Note the part number on the board, including the Rev number, and order the exact one ( or are good starting points). Universal inverters do exist but can result in reversed controls (up to lower the brightness). Replacing individual parts on the board is cheaper but more prone to not tracking down all of the bad parts.

If the inverter is good, then it's probably backlights themselves (several in most monitors). These are sandwiched on the perimeter of the monitor (usually under some tape that holds the lamp, reflector and other parts together. You need to order by length and width and get ones for your monitor size. Separate the panel from the bezel. Remove the tape, and separate the reflector (make a note of how things are put together) then you have to Dremel (or use another rotary tool) to remove the plastic to get the backlight out. (They are often molded into the frame.) Then put in the new backlight and reassemble everything. See for more information but for an overview: Then push the new backlights into place, reconnect the wires and close up the sandwich of tape and other parts around the screen. Then replace it in the bezel.

With a good spare backlight, you can test an inverter for condition (plug together and turn on the tv while the box is open). Similarly a good inverter can test the backlight.

I hope this helps.

hello Gabriel

Could you check your SyncMaster 2233 for me and tell me your findings. If this monitor is connected from your computer and when both switch on, did the led indication lamp from your monitor lit steady green? or this lead indication lamp lit green then turns red?

1. If the led indication lamp lit steady green then there is nothing wrong with the settings, configurations, driver or hardware on your computer. The problem would be the backlight inverter lamp in your monitor is busted. Or it could be the inverter board that supplies high voltage for the backlight inverter lamp that is bad. You can replace the backlight inverter lamp located at the upper and lower part of the monitor with a replacement part you can purchase at Inverter board repair can be risky if you don't have the skill. Even opening the back cover of your monitor and replace by yourself the inverter lamp is risky too, could inflict more damage. you can bring it to a local professional service man.

2. If the led indication lamp lit green then turns red, then if not the video card the power supply section from your monitor is bad, you can replace polarized capacitor with same value. Just inspect and those with blown or leaking capacitor. You can also check the terminals and solder joints for the 15-pin vga terminal connector where vga cable is connected on your monitor. Resolder the terminals.

3. If the red indication lamp did not lit at all. Power supply section in the monitor is bad. You can check the output voltage from the power supply section. +5VDC is supplied for the main board and +24VDC is for the inverter board. Replace leaking or blown capacitor with same value.

Just remember, this should be done when computer and monitor is turn off

Go check the backlight inverter lamp, replace if busted.
This can be found when you open the back of your lcd and manage to get access to it.
The backlight inverter lamp is located at the upper and lower part of the screen.
Go check also the inverter board, the one that suppply high voltage to inverter lamp, see if this ballast transformer are not burnt out.
The input voltage of the inverter board is 24vdc the output is 250v ac..The voltage input terminal of the inverter board usually creates a loose solder. Use a soldering iron to resolder them....

Those voltages does not sound right, it should have 5v for the logic board and 16~20v for the inverter board for this 20" screen size, but you are getting the white screen which means that the backlight is working, so your measurement may be wrong. The white screen means that the T-CON board is not feeding either the 5v or 12v (depend on the screen makes and model) that will be the first palce to check, the logic board supply this voltage through a switched transistor to turn the T-CON board on or off (off during standby mode).

The screen wont come on after its been in sleep mode. it just makes a clicking noise and after some cord manipulation it comes back. sometimes. lately it takes forever t come back on

If your CM2019 will do same exact thing when connected to a "known-good" pc that has all power save, and sleep modes "disabled", you will need to troubleshoot units power supply/inverter circuit. Do some reading in the fixya profiles to find out about poor soldering and bad capacitors on printed circuit board. I'll bet it's poor solder connections of power transistors on inverter circuit, or bad capacitors. 12fixlouie

Monitor on/off button flickers

The reason why the button of your monitor flickers is because the 12 volts output supply for your inverter board is not stable..
If you have the skills and the right tools for this, Here's what you need to do
1. If your monitor comes with a power supply adapter, open it..check and replace blown capacitor with same value..
2. If your monitor is using a cable power the back cover of your lcd..on the power supply section.. check and replace blown capacitor.
3. Check and resolder the terminals for fixing possible loose connections.
4. On the inverter board section...check and resolder the terminals for fixing possible loose connections, the high voltage inverter usually loose connections when overheat.
5. Other things to check if step 1 to 4 did not resolve your problem. Check and replace burnt high voltage transformer.. Check and replace busted backlight inverter..

Hope this fix your problems..

thanks.. much appreciated if you rate this help.

This model AL2017 20" Acer monitor is known for having a bad power inverter board. The capacitors go bad, which causes the backlight to completely stop working or flicker intermittently. If you feel like you are electronically and mechanically inclined the board is easily replaced. Search ebay for AL2017 Power Board -- its about 15 bucks plus shipping.

My monitor keeps going on and off. It will be off

You could have a faulty inverter board. The inverter supplies high voltage to the CCFL lamp/s, these lamps are mini fluro tubes approx 1,5mm dia. and the length of the screen.

19' Westinghouse Monitor - Intermitent come on.

The problem is either with the power cord itself (especially if it is connected to the monitor such that it stays bent all the time), or the problem might be with the socket into which the power cord plugs in the monitor. The solder joints fixing the power socket to the circuit board & connecting the power terminals to the circuitry usually tend to get loose after some period of usage either due to mechanical stress while connecting/disconnecting the power cord to/from the socket, or due to high currents passing through these joints continuously.
My suggestion is to test with a power cord which is known to work without problems. If this did not fix the problem, then the monitor will need service (monitor needs to be disassembled to a degree that permits re-soldering of the power socket's terminals to the circuit board).
