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.

Troubleshooting screen inverter and backlight on acer 5738


You are right! the inverter is the likely problem, unfortuneately unless you have another screen there is no reliable way of testing, the inverter puts out at least 1000 volts and don't attempt to check with a meter it will probably get damaged.

Laptop screen is black even with computer on.


Try to shine a flashlight into the screen. If you can see an image with the flashlight, then you have a bad inverter board or bad backlight. If you can not see an image at all, then you might have a bad video card, RAM or motherboard. Any one of these issues require your laptop to be serviced. The RAM would be the cheapest and easiest route.

Lcd back light ptoblem


Could be a problem with the mainboard, or the tube in the screen, or you recieved a dead lcd inverter.
If your not getting voltage to the inverter, but you can see a picture correctly on an external monitor, you may have a bad cable, or mainboard.
Check all fuses near where the lcd cable connects to the mainboard (you may need to look on the reverse (underneath side) of the board.

On one acer I'm currently working on,(that had a smashed screen, I installed a replacement screen, and had the same issue. So I replaced the inverter - same. I tried a good test tube on the inverter - nothing. I then disassembled the notebook and removed the mainboard. On the opposite site to the lcd connector I found a fuse labelled F2 (near a larger fuse labeled F1). This has shorted out.

I would test this before assuming the new inverter is dead.
I suspect that by replacing that you will get power to the inverter.

Unfortunately I dont know the rating of the fuse, however. I presume 12v but no idea on amp rating

Good luck

Acer Aspire 3100 series. Display screen getting dark


This is such a user error. I had the same problem on my 3100-1718. It was as simple as holding down the Fn key and using the left and right arrow keys to change the brightness... I am a goofball for ever letting this stay dark for a month !

Acer aspire 5315


Hi,

Since the Acer Aspire 5315 works except that the display is dark, then it would be safe to assume that it is only the LCD display part that is the issue. Often LCD display (of laptops) are working but only that you can not see the actual display. One way to verify is to shine a flashlight at an oblique angle to the screen, semblance or part of the desktop could be seen. If the desktop could be seen (albeit very very dark background) then it could either be the CCF Lamps (cold cathode florescent) or the inverter that powers the lamps.

Often, the defective component would be the inverter. It is relatively easy to replace the inverted. It is sometimes more difficult and challenging cracking open the casing of the display panel of the laptop than replacing the inverter. Additionally, inverters are readily available online. It is also not surprising that inverters for other brands/models would also be used in your Acer Aspire 5315.

This would be a good place to start for inverter boards. This is a nice tutorial if you are considering a DIY.

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.
