Vertical strip of flashing horizontal lines on Acer Aspire 7551G screen


More than likely it's the lcd screen and will have to be replaced. I could be the video card, but most likely the lcd screen especially when you can put pressure on the screen and cause changes. To isolate the problem try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the laptop. If the Borrowed monitor displays ok, then the problem is with your lcd screen and the video card is ok. If the Borrowed monitor displays the same as your lcd screen then the problem is with your video card inside the computer.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Once you narrow it down to the lcd screen as being the problem you might try taking the lcd screen apart to reseat the lcd cable on the back at the top of the lcd. Just unplug it and plug it back into the connector. You can also try doing the same where the lcd cable plugs into the motherboard. Just pull it out and put it back.

Monitor buying tips you should know.


Over the years monitors have transformed from those bulky CRT monitors to square LCD screens to stylish flat wide screen LCD's and now to new stylish extremely thin LED screens. On average every PC user spends at least 5 hours a day looking at the monitor. If the picture is fuzzy and not clear enough then there is a very high possibility that the eyes get damaged.

Monitor Sizes
There are many different sizes of CRT, square LCD, wide LCD and wide LED monitors available on the market at the moment.

If you want an older CRT screen then sizes can range between 14" to about 20", they use the 4:3 aspect ratio.
If you want an older LCD screen then sizes can range from 15" to 19", they also use the 4:3 aspect ratio.
If you want a newer wide screen LCD then sizes can range from 18.5" to about 27" and even larger. They use the 16:9 if they are full HD or 19:10 if they are not ratio.
If you want a newer wide screen LED then sizes can range from 18.5" to about 27" and even larger. They also use the 16:9 if they are full HD or 19:10 if they are not ratio.

Image quality
The sharpness of the image in a monitor greatly depends on your Graphics card as well as whatever resolution you are running at. Nevertheless the quality of the monitor plays an important role.

Here are some of the tips that you should know before buying a monitor.

1. There are three types of monitors namely CRT, LCD and LED. The monitor that looks like a TV is a CRT monitor. In CRT monitors there is a Cathode Ray Tube that shoots electrons into the screen to create the image. An LCD monitor is smaller in width and consumes less power and is healthier if you are going to be spending large amounts of time at your PC. The LED screen looks the same as an LED monitor and the difference between it and the LCD is that it has a much higher contrast ratio resulting in darker blacks and much lighter whites.

3. A CRT monitor is much heavier than LCD monitor as you can imagine by it's bulky appearance. A LCD monitor is very lightweight and so is a LED monitor.

4. The distance between two adjacent pixels in a monitor is called 'dot pitch'. This is measured in millimeters (mm). Smaller the dot pitch the clearer the picture quality. Usually there are monitors with dot pitch varying between 0.20 mm to 0.27mm. Some manufacturers use diagonal dot pitch while most of them use horizontal dotpitch. The diagonal dot pitch is always longer than the horizontal dot pitch

5. Resolution of a monitor has to be considered with care. Most of the CRT monitors have resolutions of 800×600, 1024×768 and 1280x1024. The square LCD monitors have 1280×1024 and 1600×1200 resolutions. Newer wide screen LCD monitors have resolutions of 1600x1900, 1680x1050 and the Full HD 1920x1090. When the resolution is higher the images and text will appear smaller. But you can see more text and bigger pictures in the monitor with high resolution.

6. Another thing to note is the 'Refresh rate'. This rate is usually 60Hz, 73Hz, 75Hz, 85Hz. Refresh rate of 85Hz means the picture on the monitor is refreshed 85 times within a second.

7. The brightness and contrast can range between a low 5 000:1 to a high 80 000:1 in a LCD monitor and an average of 5 000 000:1 in a LED, yes that's 5 million to 1 with a LED. This just shows how much better a LED monitor is to a LCD.

8. If you are a gamer then the thing you have to look at with LCD monitors and LED monitors is the response time. If it is 16ms then this is a very bad monitor for gaming and you will experience a ghosting effect in most games and if it is 5ms then you will have an average gaming experience. What you want to get is a 2ms response time monitor, with it you will have the best gaming experience with no ghosting what-so-ever.

Normally, when the monitor is switched on, a blue screen is shown momentarily, with 'acer' right in the middle, before it shows the image that the computer is sending. But now, the screen does not show...


It sounds like either a bad signal input , possibly from a loose plug on the cable from the PC or bent pins on the plug / the video graphics card in the PC/ or the settings on the monitor need adjustment. Use the OSD (On Screen Display)
---------------------------------------------------------------------------------------------------------------------
First check to make sure both ends of the cable from the PC to the monitor are not damaged and are seated good & tight.
If those are fine then unplug both cables from the monitor & leave unplugged for 10 minutes or so to see if the screen has an automatic reset.
If that does not work then use the monitors OSD (On Screen Display) to adjust to default settings. If that does not work, plug the monitor into another known good PC.This will tell you right then if its the monitor or "Your" PC.

I think there is some severe problem in the VGA of the laptop, that is not supporting your LCD. There may be some thing relating to a very sensitive golden color strip in the laptop that is used to VGA signals. If you have opened the laptop for repairing then it can be a issue. Better to try another VGA first and then tell me what happened.

Monitor


Monitor sizes are measured on the diagonal from corner to corner.

A 17" LCD may have a screen width of 12 inches measured from side to side.

If you are measuring a old style CRT monitor (Cathode Ray tube) the visible screen area will be about an inch less as there is about 1/2 inch of plastic frame holding the CRT in the chassis. The manufacturer can advertise the actual size of the screen regardless of how much is actually visible to display information.

If you are talking about software not utilizing all the available screen area to display the image, that is an issue with the people writing the software code not keeping up with the changes in hardware.

In the past year or two, most displays have switched to the 16:9 and 16:10 wide aspect ratios while most web content is still written for the 4:3 old style aspect ratio. Eventually, software developers will catch up with cusrrent hardware.

It sounds like the logic board inside your LCD is broken.

I would look on ebay to try and find the part and then take it to a local tech to replace it for you as I would not recommend anyone take apart a monitor (LCD OR CRT) if you had never done so before.

OR, Buy a new monitor.

SDM-P234/B Won't turn on


Follow this procedure to troubleshoot the monitor. NOTE: Since each of these steps represents a possible solution to this issue, check the display function after completing each step. 1. Download and install the latest video drivers for the video card. 2. Disconnect the computer and monitor from any surge protector or power strip and plug it directly into a known working wall outlet. NOTE: If the display returns after completing this step, the problem is isolated to the surge protector or power strip. 3. Ensure the monitor cables are connected correctly. 4. Perform a monitor self-test. 5. Adjust the monitor brightness and contrast levels. NOTE: Refer to the monitor manual or user guide for specific instructions on how to adjust the monitor brightness and contrast levels. Manuals are available online in the Manuals/Specs/Warranty section of the Sony® eSupport Web site. 6. If possible, connect and use the monitor with a different computer. NOTE: If the monitor functions properly, then the problem is isolated to the computer to which the monitor was originally connected. 7. Ensure that the keyboard and mouse are connected correctly. 8. Troubleshoot the computer display configurations in Safe Mode. 9. Remove any hardware that has been added to the computer. This includes any added memory, internal or external drives, and any type of adapter card (network, sound, video, USB, etc.) . Let me know what happens. Good Luck, Tim
