Screen goes black but power button still green

Ok - problem is that my monitor randomly goes black. I say goes black, not turns off, because the monitors power button stays on(green lit). My monitor is a 23 inch TV that has a VGA connection on the back. Its an Insignia(best buy brand). When it goes black all I have to do is push the VGA button on the remote and the picture will come back. Some times it goes black within a second again and I push the button again. I do this usually 4-5 times and the monitor will start to "cycle"(going black and showing picture) about 3 times then the picture will stay on. Some times it stays on for hours - some times the problem happens within 5 minutes. Here is a video in case my description absolutely sucks.

SOURCE: 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.

So the big problem these TVs have is that they are built with generally cheap parts. At the same time, the parts have the potential to be reliable, but little things like poor board design or cheap capacitors ruin them.

For this TV, the likely problem is the power board.

The first thing you should try is to be sure that the TV is still working, even though the screen is black. You can do this by hooking it up to something, like a dvd player and check to make sure it still has sound. If it doesn't, it still may not be a big problem, but it has the potential for being more than just the power board.

If it does still have sound, you need to disconnect everything, open up the TV, and remove the power board (the board with the power plug either on it or connected to it). I would suggest investing in a multimeter with which you can test capacitors, fuses, and circuits in general. At that point, you should check the board for obvious signs of issues.

1) One big one would be noticing if any of the capacitors (cylindrical electrolyte caps being the more likely issue) are blown or bulging out at their top or bottom.

2)You can also check the fuse, although be aware that the fuse may be a microfuse that looks nothing like those you may be familiar with.

3) In general look for areas of burns or darkening or damaged looking parts.

I would replace any fuses or capacitors that you need to replace using a soldering iron and good solder. Be careful not to bridge connections with excess solder, and in general stay away from this unless you spend some time getting acquainted with soldering parts onto a circuit board. You may potentially damage the board further if you don't know what you are doing.

Anyways, check if that fixes the problem. Any thing more than that would likely be both too difficult and too costly to repair, unless of course you manage to get a good deal on a power board. At the same time you should know that the power board might not be the only problem.


If the power board looks fine or is not the only problem, then:

It is possible that the problem you are experiencing is the result of a bad backlight panel. This can be fixed by either replacing the whole LCD panel or simply the backlight panel - for example you could get your hands on a broken LCD of the same size and switch out the panels, but thats a lot of work. I also know that repairing the backlights themselves is possible and there are tutorials online, but its riskier and more difficult.

There are two possible causes for this problem, either back light inverter board stop working thus screen goes black as lcd screen needs back light to show its image OR if sound remains while screen goes black then it seems firmware issue.
Let me know is it Insignia NS-LCD42HD tv or any other model?
Do you get sound in tv while no picture?
Does screen show any on-screen display when tv lose picture?
Above info will help me to diagnose problem in tv and to suggest some solution.

Monitor goes black - green light stays on

My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.
  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.

Screen won't turn on

You can try to do the monitor self test.
Monitor Self Test:
1. Physically test the monitor autonomously from the computer.2. Switch both the monitor and the computer off, and then disconnect the VGA cable le from the computer.3. Turn the monitor on, pressing the power button for about three seconds. The self-test screen will come up .4. If the image is clear, bright, and shows red, green, and blue, the monitor is working properly. Video issues may be due to the video resolution in the computer, and not the monitor.5. If the image is not apparent and intense or the colors are not accurate, then the trouble is with the monitor or some of the (OSD) settings. In this case, test your particular monitor's information for OSD.
It is always important to check the color of your power light for so you can distinguish if the monitor is defective. Getting red lights on the the power panel states that the power section of the monitor is faulty.

Montior goes black i turn off the monitor and turn it back on i can do about 2 things and screen goes black again repeat this as many times as i want. Gateway FHX2300 monitor

My monitor has been switching connections on me randomly. Hit the menu button. The one to the left of the power butter when facing the screen. Hit the left arrow twice then hit the menu button again. This will open up the screen where you can choose one of three inputs. I'm going to assume that it is on the incorrect input so use the arrow keys highlight what input you are using and the hit menu button again and your screen should return to normal. Mine only does this randomly when it goes into screen saver, hibernate or sleep. I don't know how to permanently get it to stop doing it though.

Monitor Blacks Out Randomly

Well If the monitor is brand new and you just purchased I would take it back and get another one as it appears to be defective. Most stores will allow you to exchange a defective item without a problem as long as you have the receipt. Any attemot to make repairs yourself could void the warranty. If it is used it may still be under warranty...I would get the model/serial number and contact Asus to have repairs made. Most monitors have at least a one year warranty.

When turned on, no picture, sound or response. LED is OK

I had a similar problem with my HANNSLounge 32", the screen switched on with green light but none of the front panel buttons worked (screen is black apart from showing the input source in the top left).
After powering off numerous times I tried starting up with a blank SD card in the reader and the tv cycled between red green and blue screens and then reset itself. (Some sort of firmware restore?) After which point I had a working screen again! (Will have to see how long it lasts for!)

Westinghouse LCM22W2 shows a display then turns off after half a second

I have the same problem and have traced it down to a potential power supply issue.  I bought mine at Best Buy in '06 and was told today that they will test the power supply for free.  It may range from $50.00 to $100.00 depending on where you can get it.  This does not include labor for those not qualified to work with electronics.  Hope this helps you.
