Cracked Laptop Screen? Screen Dim?
Screen issues are usually easy to fix because they fall into one of two categories:
- Cracked laptop screen or has lines across it.. The screen is smashed.
- The screen is dim.
The solutions are usually very simple:
Can a laptop screen be repaired?
Repairing a cracked laptop screen or one which smashed is pretty much impossible and not something I recommend you attempt. So can a laptop screen be repaired? Well, unfortunately the answer is no the screen is not repairable and you should always just REPLACE IT.
Most screen replacement is straight forward with a few exceptions, following the guidelines found within the 8 steps to taking apart any laptop should give you the confidence to replace any laptop screen. For generic instructions that will apply to most makes and model of laptop please see the next page on laptop screen replacement.
How easy is laptop screen repair / replacement?
It is fairly simple to replace a laptop screen, the first few times you do it you may be a bit unsure but if you follow the guide I have written in the laptop screen replacement and watch the video I have created you should find it easy enough. In the video I take apart 3 different types of laptop to show you (once again) that there is a PATTERN you can follow when repairing a laptop.
Remember there is a PATTERN between the different manufacturers
Each brand / manufacturer has slight differences but on the whole they are put together in a similar way, so similar in fact that removal of a bunch of screws and unclipping the screen surround will become second nature after you have done a few.
Here a few questions that I get asked quite often (please remember that I show you the steps for laptop screen replacement/repair in the next page):
Question: What size screen and type etc can I use to replace my laptop screen?
Question: Can I replace any parts of the screen rather than replace it?
Question: What are the laptop screen price and costs?
A dim screen is usually caused by a faulty power Inverter (also called the FL Inverter) or the cable that leads into it. When you remove the screen you will see the FL Inverter attached (usually by a single screw), here is an image of one:
Here’s how to test a dim laptop screen
Plug in an external monitor and power the laptop up. (I recommend you have a monitor in your toolkit if you are repairing laptops for customers).
If you see a normal picture then use the laptop screen replacement guide to remove the screen cover. The chances are is that the FL Inverter has failed or has a loose cable attached to it. The FL Inverter is very simple to replace, it is held in usually be a single screw or occasionally stuck with glue.
If you come across an FL Inverter which appears to be attached in some bizarre when then you can always find many YouTube videos or blogs that will show you exactly how to disassemble your laptop screen and remove the FL Inverter.
Type in the specific model of laptop into a search engine along with the words ‘screen replacement tutorial’ or something similar.
This may sound like cheating but it’s what all technicians do so I see no reason to advise you otherwise. I have been repairing laptops for many years and I still do this on the odd occasion.
However, having said that you should have no problems whatsoever replacing any laptop screen having followed my guide. If you have any problems or questions then please get in touch and I will do my best to assist you.
- Check the cable to the inverter for a loose connection.
- If you have a spare that you know works then swap them over and power the laptop up. If it works then order a replacement part.
Again, Google for the part number which you will find on the inverter and choose the best source based on reputation and price. Many sellers on places such as Ebay are cheaper than trade suppliers. For this reason my own advice is to go with whatever you think is best – but be aware that trade supppliers are not always the best option!
Typical faults with a laptop screen
I get a lot of emails with very specific problems and makes and model of laptop. One of the core things I like people to understand is that the purpose of Tekmoz is to show you that can apply a set of rules to almost ANY MAKE, ANY MODEL OF LAPTOP. The steps for repair or replacement are not always the same but they are very similar. But below are a typical list of questions and problems that I have answered. My answers may help you to fix a specific problem or if you get stuck, but as usual please feel free to ask a question:
Question: My laptop screen is dim, I can see the picture but it’s very faint, what’s the problem here?
Question: How can I tell if it’s the FL Inverter at fault or the graphics chip?
Question: My screen keeps going dim and then bright again at random times.
