Sony SDM-HS75 tft lcd monitor

The monitor, when plugged in goes dark, after about 30 seconds. I can turn it off and then on only to have it be normal brightness for 5 seconds then dark again. At first I thought it was completely turning off but I can barely make out my background now, so it is on; there is just no illumination of the picture, please help.

Failing Inverter An inverter, typically found inside a laptop computer, consists of a small board, which has impregnated electronic circuits stamped on it. Inverters look like thin boards about the of two sticks of chewing gum. The inverter and its bulb control the intensity of the liquid crystal display, which lights the screen monitor. The computer can control the output voltage of the inverter and either lighten or darken the screen. A special type of inverter can adjust the brightness of the screen by using an internal sensor to judge the room brightness, and then adjust the screen accordingly. Failing inverters give off some specific warning signs, which can be recognized by observing different screen characteristics.

Short Intermittent Display Upon turning on the laptop, the screen flashes on in the normal mode for a short period and then blinks to black. A very faint image appears in a dark background, which will be very hard to see almost invisible. After shutting off the laptop and restarting, the same mode occurs, where the screen appears normal for a few seconds then fades to black. This condition points to a failed inverter. To confirm this, plug in an operational external monitor; if the external monitor functions, the inverter has failed. b> Total Blackout with Ghost image b> The laptop turns on, as indicated by the power supply button, but the screen comes up black. The screen comes up black after restart. You might be able to detect a very dim or ghost-like image on the monitor. When you plug in a known functioning external monitor, the external monitor operates normally. This mode of display indicates a failed inverter. b> Long Term Periodic Operation b> With this failure mode, the laptop screen illuminates normally upon start-up and remains that way after several minutes, hours or even days, until it goes very dark again. Brightness controls or restoration attempts do not work. Most often, the screen will function normally with a computer restart, but will eventually return to black. Faint ghost images might appear, as seen in the total blackout mode. b> Dark With Color Variation b> Upon computer start-up, the monitor shows black or dark gray, accompanied by very faint images. The screen might have an intermittent color change, or remain on with a non-standard color variation, like pink or red. b> Auto Control Switch b> If the screen appears black, with no faint or ghost images, look for the lid switch near the back hinge. The switch, when depressed with a closed lid, shuts off the computer and monitor functions. Sometimes the switch becomes stuck in the closed position, disallowing the computer and monitor to turn on when opened. Pushing the switch manually several times can often free it up. If the switch tab has broken or jammed inside the case, it needs replacing. b> Loose Connection In this mode, the display looks normal upon start-up, but tapping the side case of the computer turns the screen black. More tapping results in the screen functioning normally then cutting out again. This condition points to a loose wire connection from the inverter to the LCD backlight lamp, or the video cable. The connectors can be accessed by removing the monitor bezel screws and pulling the plastic retainer off. Both connectors can be cleaned and refitted.

I have a samsung syncmaster 943NW which goes on for about 5 seconds and then just goes black. When restarting the screen it does the same again, goes on for about 5 seconds and then black. Is there...


I had the same problem with this monitor (Samsung 943nw)
When turned on it would only stay on for less then a full second.
When shining a light on the screen I could see what was on it, so it was just the backlight that was shutting down.

After I turned down the brightness of the monitor, the next time I powered on the screen the backlight stayed lit and it was back to normal.

Screens goes dark after 3 seconds


Your power supply probably has a blow electrolytic cap on it.

You need to pull the power supply board out and have someone replace the electrolytic caps on it. Believe me....if the one for the brightness is bad...they are all suspect!

Caps are cheap...but knowing how to open the monitor and do the soldering is the part that takes some skill and may be costly.

Good luck and be careful.

Syncmaster 226bw goes black


If you can still faintly see data on your screen, it will be a faulty backlight in the panel most likely.

LCD panels have fluorescent tubes in them that provide the light needed to see the data. If one of these goes faulty, the circuit that drives it will turn off ALL the backlights, giving you a black screen.
Note: a faulty circuit that drives the backlights will often give the same apparent fault.
You will need to take the monitor in for repair.

L13V36 Dark Screen, picture can be seen in bright light.


If the backlight lights up for a second it's probably fine - It lay odds on the display inverter in the screen. Actually finding parts for anything made by gateway may be difficult, however. They do not sell spare parts. Considering the size of the LCD i bet it would almost exceed the replacement cost of the screen to repair it

Scceen flickers on and off


You'll have to describe the problem in a bit more detail, because it could be a couple different things based on when it goes dark and what "dark" means.

I'm going to guess that the monitor is turning itself off after that second, but you might be describing that it doesn't say it's off, but there is no image (or maybe a really faint image that you can see in the bright light). Try checking it in the bright light after it goes dark. Also, does it seem different if you bang on, shake, or turn it upside down. Don't do this if you haven't already as it will more likely damage it than fix it, but if you have already banged on it, does it change?

I'm working on the same model with a similar problem (not sure it's the same) and will be ripping into it soon and will post the results.
