Toshiba satellite monitor problems

The monitor no longer responds. It remains black. This was after switching from an external monitor back to the internal monitor. I removed the extra memory module and hard drive. When these pieces were placed into another laptop, the hard drive functions fine, however the extra memory module causes the screen to go black, there too. I tried to replace the hard drive in the old toshiba, but the screen still remains blank. Any and all advice would greatly be appreciated.

Sounds like the memory module is bad. Return it or get a warranty replacement.

Lg w2343t monitor


try monitor on a different working desktop to see if it works, both on the external and internal video card ports. If screen menu buttons fails to respond, fault is either on menu buttons or you may have a burned out lcd screen, try a different monitor on your desktop pc to check its functionality. Monitor probably needs replacement.( It might not be burned out for you mentioned "no signal" error message appeared on screen, have the screen menu buttons checked)

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.

It boots up and I can hear the HD ticking over but the screen remains blacked out


Hi. Connect an external monitor then power on your laptop and see if you get a display on external monitor. If display works on external but not on your internal LCD, you need to replace your LCD. I would suggest to have a qualified technician check your laptop to see if you need to replace the whole LCD assembly or just CCFL or inverter.

Screen went black


Swap monitor connections to determine if one of the monitors is not working.
If one is not working you probably have an internal problem. If power led responds to the off-on button but no picture is seen, the inverter has likely blown a fuse. Replace the fuse and resolder the leads on all 6 inverter transformers or the fuse might blow again.

My monitor will remain black when notebook is powered up


Black uses much less power. It's a device for automation, so you really should not lavish the watts and attention on it unless it has to perform something truly novel.

If you really want to use the monitor though, you can use the function-key combination used to switch the display between internal and external displays.

Acer aspire external monitor not responding.


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
