Question about Dell Inspiron 1300 Notebook

Still having the problem with the LCD screen

I did clean and reseated the invertor board connection and this seem to work for a couple of days. I am back to the same problem with half the screen black with vertical lines. Could this be a problem with the invertor board? Should I try to replace this board or go through the cost of replacing the LCD screen? At this point I cannot even press on the top of the screen to get the full screen to reappear.




screen is dark bt if you shine light on it can see screen icon ets - closing lid and openening quickly screen comes on for few seconds then you hear a click and goes dark again
sometimes can emain on for an hour or two

Most likely it is the inverter and or the back plain lamps that are failing. In screens where these are replaceable, I always replaced both the lamps and the inverters at the same time. A bad lamp can damage an inverter.

Why are all the lights on LCD screen on?


How to troubleshoot and fix video problems
Here are some tips and tricks for troubleshooting and fixing laptop video problems. Video issues are very common within portable computers and with the following tips you should be able to detect and eliminate basic laptop video problems.
Laptop LCD screen has a faint image.


all-lights-lcd-screen-4ztirbadqll2ypvmakqp10pq-2-0.jpg
Look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the backlight stays off even when you open the LCD screen or turn on the laptop. The switch turns off the backlight when you close the LCD display to save the laptop battery power. Check the LCD lid close switch. Usually it is a small plastic pin located close to the LCD hinges. Try to tap on the switch a few times to turn on the backlight. If after tapping on the LCD lid close switch the backlight stays on, you fixed the problem.
It is also possible that after tapping on the LCD lid close switch the backlight works fine, you see a normal video on the screen for some time and then the backlight turns itself off again. In this case I would blame the FL inverter board. Try to reseat cables on both end of the FL inverter to make a better contact between the cables and the FL inverter board. If it doesn't help I would try to replace the FL inverter board.
Laptop LCD screen is solid white color.

Most likely it is just a bad connection between the LCD display and the system board. I would try reseating the video cable connector on the back of the LCD screen first and check if it fixes the problem. After that I would try reseating the video cable connector on the system board. I would also try reseating cables if there is no video on the LCD screen at all.

Try to connect the LCD screen to an external monitor. If the external video is fine, you have a problem with the LCD screen or the LCD video cable. You can try to fix the problem by reseating the video cable on the back of the LCD and on the system board.
If you see the same garbled video output on the external monitor most likely it is not the LCD screen problem. In this case the system board (with onboard video) is bad or the video card is bad.

GOOD LUCK.

Dv4000 screen is on for a few seconds then goes black. Replaced screen balast and worked for 10 minutes, then went black again as before replacement. Should I replace the lcd screen?


No. The bulb is good. It could be the DC/DC invertor - that little curcuit board just beneath the in the LCD - or the video off the notebooks motherboard. - personal experiance points to that invertor

This requires to take the laptop apart google the name brand and model number for a guide for taking apart.

No display on lcd screen


check for lcd invertor if its ok its problem of vga chip
2 ways to solve
1) go to nearby service center which they just replace the motherboard
2) more risky bt work dissamble the whole laptop nd all accries from the motherboard including the cpu ram wifi card nd also black sheet from the main board then place the board in microvave where the vga chip is on the top nd microvave for 6 min at temp of 350 -390 f
now try the run the board

No video in the display


gues the LCD display is not working,
1 the LCD screen is out or
2 the backlite inside the LCD screen is out or
3 the invertor board behind the LCD screen inside is out.

My laptop is only 4 months old and my screen is very dark. I can hardly read the screen.


The connector that goes from the mother board or the invertor may be bad. Or the inverter board itself.
The wire is very delicate and goes from the motherboard and the invertor wire is also delicate. Repeated opens and closing of the screen can make the conections at the plug get weak and break.
Try connecting a LCD monitor alongside the laptop. Select the LCD and see if you get a video feed. If so then the wire connector and / or inverter is probably the sourse of your problems.

Replacing LCD Screen


it depends on if the exisiting invertor is fine or not. If the panel is being replaced because it was cracked etc, then the chances are the invertor is fine and will not need replacing. Obviously if you don't get the same replacement panel that Dell originally used, then you may have to buy a different invertor & figure out the wiring connections to attach it to the motherboard.

Compaq nx5000 - will not power up. DIsk spins, green lights for a second , then powers down to only yellow light. SOmetimes - seems after long periods of no use - -powers up and runs. Have sourced new...


I just got my nx5000 up and running again. The memory needed to be reseated in the socket (got this tip of the HP site) All I did was open it up and reseat the ram - just took it out and put it back in again. Problem solved. I also took the opportunity to vacuum a little bit of dust out, but I don't think this was anything to do with the problem.

Get a copy of the service manual (Just google "hp service manual nx5000") it has easy instructions at how to get to the memory - it is just under the keyboard.

Hope this helps!
