Advent 7111 narrow screen


If the display isn't going full screen, on that 15.4 inch TFT LCD screen, the problem is the screen Inverter, or LCD screen itself.

90 PERCENT OF THE TIME the fault is the screen Inverter.
It isn't a simple screen resolution setting that needs to be changed.

Primer:

An LCD screen does not produce light by itself,

http://solutions.3m.com/wps/portal/3M/en_US/Vikuiti1/BrandProducts/secondary/optics101/

It needs an additional light source.
The additional light source is a Backlight.

A Backlight can be a CCFL, or a series of LED's.
The Advent 7111 Notebook PC uses One CCFL,

http://www.screencountry.com/index.php?section=products&model=7111&brand=Advent&size=

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

(Average size is 2mm Thick. Length is almost as long, as the LCD screen is in height. 2mm is close to 1/16th of an Inch )

A screen Inverter is used to convert the power from the laptop, for the Backlight, and LCD screen.

Primer over.

I don't have access to a Service Manual, for the Advent 7111 Notebook PC. I haven't had one come to my shop for repair.

I DO have years of experience at repairing laptops, and I see the Advent 7111 is just a basic laptop, as I HAVE repaired over the years.

If you wish, I can guide you step by step, in replacing the screen Inverter.

(MANY people go out, and buy an LCD screen, when the problem is a much less expensive screen Inverter. Afterwards they buy the screen Inverter. Too bad they didn't come here first)

[ The Advent 7111 Notebook PC is just a re-badged Quanta TW3M.
According to the source, you should see TW3M on the bottom of the laptop.

Screen on laptop advent 7102 very dull can hard use it hardly any brightness


The LCD screen for the Advent 7102 does not produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

An Inverter (Screen Inverter) converts electricity from the laptop, for the LCD screen, and the Backlight.

90 PERCENT OF THE TIME the fault is the Inverter.


The Inverter is a small circuit board located behind the Display Bezel, and under the LCD screen.

[ The Display Bezel is the thin plastic frame in front of the LCD screen. Resembles a picture frame ]

My advent laptop turned off suddenly and now it turns on but its a blank screen


Check it is not overheating, common issues with Advents are the death of the Graphics chip as this is cooled poorly by the fan. You can usually remove the large inspection hatch under the laptop and check that the fan is not clogged with debris and dust. Try cleaning it and see if that helps.

Also try to plug the laptop into an external monitor, if you get a picture on there, the graphics chip is working ok and the problem lies in the screen inverter or backlight. At this point, unless you are technically confident, it is best to take the laptop to a repair shop to have the screen and inverter tested

I have a almost black screen on my 7111, when i start, i see the advent logo perfect, and then it gos almost black, i can see the screen very very faintly or weak in the background. Do i have to change the...


There are two parts responsible for lighting the display. First is the CCFL (Cold Cathode Florecent Lamp), which is the back light and the second is the Inverter board, which provides high voltage to the CCFL. Either of the parts can be faulty or in some rare cases both. But most likely it is the CCFL (Lamp). Its life is limited and depending upon how long it has been in use, you can have a better idea - if its the CCFL or Inverter.
Rest assure that your system is ok and you can check it by connecting you laptop with some external display, which would work fine if the graphic card is ok.
So, my advice is that you get it properly checked by any professional for replacement of CCFL or Inverter.

Advent 5431 screen all mashed up ie cant workout what anythink says on the screen at all,when i plug in external monitor screen is ok..changed screen with a working laptop screen and changed inverter still...


Most probably you have a defective LCD screen cable. This is the only possibility left since you have changed the LCD screen & inverter, & an external monitor works fine. Check your LCD screen cable & replace it if necessary.

Advent 7098 faulty screen?


Angle the screen to the light. If you can see a faint screen image then it's probable that the backlight's inverter has either failed, it's cable has become damaged or the backlight has failed. Both of these can be tricky to replace unless you have the right tools, but can be done provided you can get a spare. Usually it's a tech job.

If the image is not there then it's either the screen itself, the graphics chip or, more likely, the ribbon cable that connects the screen to the motherboard.

You can rule out the graphics chip by plugging the laptop into a monitor.

Of course, the ultimate problem is that you've bought an Advent laptop! And most techs agree that Advent produce the worst laptops in the world. :(
