The screen on my Toshiba Satellite A75-S231 was replaced but the image is not displayed properly
I have a Toshiba Satellite A75-S231. When my grandson was using it my granddaughter in a tantrum threw a tennis shoe at him. Unfortunately it missed him and hit the laptop screen. It cracked it in several places and basically ruined it.
I found someone who had one for sale. He claimed that it worked perfectly” and that it had been taken out of a laptop with a faulty motherboard. It wasn’t just the screen but the whole cover for the same model.
When I got it I methodically disassembled mine and the replacement. I removed the screen from mine and put the replacement in it. Since it was the first time I tried this, I very carefully unplugged the old one and put the new one in replacing the three plugs that I had unplugged. I believed one to be the power which was down in the main case. The other two were in the long part at the bottom of the cover below the screen. I then reassembled it.
When I powered it up, to my delight the screen came back on and began to paint normally. I tried a few exercises with it and it seemed to be working fine. Then I noticed that it was not using the entire 15.4 inch screen. The display was closer to 13 inches. The right side of the screen (about 20%) was black. It is still black even though the 13 inch picture seems to be perfect.
Is there some setting that I am unaware of that can correct this or is the replacement screen faulty somehow?
God forbid that it was my installation. It seemed so simple and straightforward but I wouldn’t stake my life on it. The original screen did not do this. The display filled up the whole screen.
Can you please help me?
First of all, I would try to change the screen resolution and see if it makes any difference. Right click on the empty desktop area and click on the properties line. When the display properties window will appear, click on the settings tab. Here you’ll find the screen resolution slider. Try to set to a lower resolution, let’s say 1024*768 and save the settings. Does it make any difference? If the video is normal, try to set it back to original resolution 1280*800.
When you turn on the laptop, the red Toshiba sign should appear on the screen. Is the sign centered? Is it right in the middle of the screen?
You can also try to boot the laptop in a safe mode. Turn on the laptop and press F8 for a few times when the red Toshiba logo appears. It’ll give you a menu, select the safe mode line and press enter. When you boot into the safe mode only most important system files are loaded. The laptop will boot with a basic video driver. If the video is displayed correctly in the safe mode but not in the normal mode, then you might have a problem with the video driver. Go to the Toshiba support website to download and install a new display driver.
By the way, do you know with model the replacement screen came from? It’s possible that the screen is the same size but it requires a different video cable.

I have had the exact same problem with my Toshiba A70. I dissassembled the notebook to clean the heatsink, and when i reassembled it the screen was about 13 inches and 4:3 ratio. The image was not centered in the screen but it starts in the top left corner. It doesnt matter if its in post, windows or linux its always like that. Its as if the LCD thinks its a 4:3 and tells the computer as much. Its a perfect image with no garbled lines. I wonder if static damaged the chip so it thinks its a different resolution.

Of course in my last post the comment software removed the spaces it thought were unnessasary so i guess you can ignore that.

Hey Colin,
Have you tried to re-flash the BIOS?

Hi,
I didn’t know where to post this issue so I decided to put it here. I have Toshiba Satellite L10-119. I decided to put WiFi antenna behind the LCD screen. Finally it didn’t work well so I removed it from there. Since I assembled my laptop back together again I noticed (but I am not 100% sure that the issue started from this moment – rather 95%;) 2 brighter areas on my LCD. These are not stuck pixels as screen works fine there but they are just brighter areas (especially visible on bright background e.g. Word). I was very gentle when I disassembled my notebook and I don’t remember hitting or pressing the LCD on the back.
I’ve read somewhere that this may be a matter of foil that reflects light from the backlight lamps.
Is there any way to repair it? In any other way the LCD is OK but this is pretty annoying.
Thanks in advance.

Minek,
I don’t know what is causing that. I have exactly the same problem with my Dell Latitude D610 witch I’m restoring from water damage. The water got inside the LCD screen and damaged one of the layers inside the screen. The white sheet-background had some water marks. The screen itself was working fine, but the liquid stains on the background were very noticeable. So I completely disassembled the LCD screen and replaced the background. After assembly I noticed that I have a couple of brighter areas. Not sure if I had it before because I was paying attention only to the damaged area.

Hi,
I found a similar isssue on the net that came out some time ago in some Power Books (as far as I remember;) Theory is that this is caused by pressure applied to the back of the LCD screen but as this was probably a design flaw of a particular series of Power Books such thing didn’t happen to me – at least I’m pretty sure it didn’t. If you have any new info regarding this issue I would be very grateful for any help
