Screen pixels detection problem

Hi,
I have a quite noisy screen image with all screen pixels on. I need to detect all pixels from the screen but i have problems to find them all. So, my question is if it is possible to detect all 8192 pixels from the picture? I know it is possible to do in parts where I draw ROIs separately to objects which are not found by Detect Objects step but this is not very professional. Is there any way to process image to ease the detection? I tried couple of methods but none worked perfectly. See attachments.
Br,
Jick

The first thing I would do is calibrate the image to remove any distortion. After that, if you know the coordinates of all four corners you can easily step through all the points using a grid approach. You could do centers or edges, doesn't really matter.
Of course, this would all need to be done in LabVIEW.

My iPhone 6 wont come on when home button is pressed and screen pixels out and fades. Any one have fix or same problem?

My iPhone 6 wont come on when home button is pressed and screen pixels out and fades. Any one have fix or same problem?
When I press the home page the screen activates but stays black. I have to press the side button to turn if off then may have to repeat several times to get my phone to come on. Sometimes while using the phone the screen will become pixelly and start to fade away leaving a white screen with vertical line on it. I have to use the close button to make it go away.

If one of the two major buttons of your phone is broken, it is unfair to expect normal operation to be available. The first resolution to any problem involves a usable Home button, as does the second option for resolving any problem. Get your Home button fixed.

Persistent blue screen of death problems on Toshiba laptop pc; need help

hey, guys,
I was hoping you could help me out here. I have been experiencing persistent blue screen of death problems on my Toshiba laptop since December 21 of 2014. The first two times I started having theses persistent issues, I downloaded a bunch of redundant programs and games onto my computer, some of which were virus infected. I had these programs on my computer for a while before my laptop was taken in for repairs. I eventually uninstalled some unnecesssary programs from my pc, hoping it would have fixed these issues, even tried windows update. I didn't have a clue that my problems were due to virus infections/malware until the two most recent times my computer was taken in for repairs; I had always been thinking it was a defective driver. My laptop has already been in for repairs at least twice due to these perpetual BSOD problems; I had Norton Internet Security installed on my pc before the Geek Squad team (who repaired my computer and found 312 traces of malware in my system during the virus test; I was told by them that I had mistakenly downloaded infected web browsers onto my pc) switched me to Webroot SecureAnywhere (they said it was better at detecting viruses/malware than my NIS), but even after my pc has been through repairs twice in a row, I am still experiencing blue screens (this only seems to have happened once each week, and on one occasion, I went through almost two weeks without it occurring). I am pretty sure, that I haven't downloaded anything onto my computer infected with viruses/malware (each of the scans done by my Webroot antivirus have found nothing), I have only a few games/apps installed on my pc, and what I downloaded all came from Microsoft's official website. I can't afford to be wasting any more money on repairs, and I am desperately searching for any possible way to fix this myself. Any help would be appreciated. I have a copy of two of the memory dumps from my most recent crashes (I also have the dump reports from my most recent crashes dating back to March 6; I got these from an app from NirSort called Blue Screen View, if you need those) I also have my system specs:
http://1drv.ms/1I6AsaE
http://1drv.ms/1Qdsb7T
Note that many of these earler dump reports (the ones from March) came from viruses. The ones from most recently as last month, I am not sure about.

Thrashing about this way gets us nowhere.
Best to restore the hard disk to its original out-of-the-box contents.
Settings > Change PC settings > Update and recovery tab > Recovery tab > Remove everything and reinstall Windows
Use the freshly restored machine for a day or so before any installations of hardware, software, or updates of any kind. If you get no crashes, the problem is not likely due to hardware.
Then add updates and other things slowly, keeping track of them. If you get crashes after that, give us the corresponding dmp files.

Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

My Ipod touch screen will not come up unless I conect it to the computer. It never gets past the apple logo and never fully retores? My screen is crackd a little at the bottom. Is this a screen or software problem?

My ipod touch 4will not respond unless I hook it up to the computer. It never goes pasthe logo apple screen.It never restores fully. Cant tell if this is a screen or software problem.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I have a 17" Macbook pro with flickering red and cyan(blue) lines across the screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem.

I purchased my Macbook (17") through a certified apple tecnition in August 2012, it was refurbished and the motherboard was completely replaced. I do a lot of photo editing, but I have been unable to do so because of the red vibrating lines that interrupt my screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem. I brought the computer back to the technition I purchased it from and he said that it was a problem with my fan, so I have two new fans but the issue is still occuring. He says he doesnt know whats wrong. Does anyone have any information on this issue?
Here is an image of the issue

I recommend having your Mac serviced by someone competent. A force sufficient to "blow apart" the fans was clearly excessive and may have damaged the display cable, as well as any number of other problems.
Dust is properly cleaned with a vacuum, preferably one designed for computer service, and they are not cheap.
Compressed air should never be used. It just blows dust everywhere, often into places where it can no longer be removed.

Detection problems in IE?

I discovered last night that the Javascript Flash detection
is no longer working in Internet Explorer on either of my
computers. The script cannot recognize that I have Flash installed.
I'm not sure exactly when it quit working, but I went back and
looked at sites I haven't touched in months that WERE working, and
it doesn't work on any of them now. I recently did a Windows update
on both computers so it's possible something happened, but I
haven't been able to find any info online about any issues. If I
disable Flash detection, everything runs fine, so my Flash
component itself seems to work properly.
On this computer, I have Internet Explorer 6.0.2900... and
the Shockwave Flash object lists file Flash9.ocx. I tried updating
to the most recent version of Flash on my laptop and that didn't
fix the detection problems.
I'm using the standard script detection from Flash
Professional 8.0. The problem seems to be with the lines:
set swControl =
CreateObject("ShockwaveFlash.ShockwaveFlash." + CStr(i))
if (IsObject(swControl)) then
The If statement is returning false for every version. Anyone
have any ideas about what could be causing this?
Edit: Ok, if I change the line above to:
set swControl = CreateObject("ShockwaveFlash.ShockwaveFlash")
Then the IsObject() function returns true. And the line below
that:
swVersion = swControl.GetVariable("$version")
seems to return the correct version.
So far, in my testing, this actually seems to work. (Although
I can't be sure if it works on browsers that aren't broken the way
mine seems to be.) So did something happen that suddenly makes IE
not allow you to create the object using the version number? And do
you NEED to use the version number?

Sounds like there may be a problem with your install ..
perhaps you have two
different play version on your PC (eg you've installed a
newer version, but
old one didn't fully uninstall itself).
One possible solution (if that is the case) is to run the
uninstall utility
from Adobe, then search your harddrive for any files matching
*flash*.ocx ..
and if they are actually flash players (look at properties
version info tab
to ensure they are macromedia/adobe flash player ocx's -
don't want to kill
something to do with flash memory (say)) then delete them.
Also kill off
the c:\windows\system\macromed\flash folder .. so then you
have no flash
player ocx left. Then go to the Adobe web site and
re-download/install the
latest Flash Player. NOTE: if you do this, be very careful
you only delete
things that can safely be deleted without causing problems
elsewhere.

Screen pixelation

So i got a lenovo yoga 2 and after a while of it having great screen clarity it randomly starting having pixelation on the screen. It even has the occasional line go horizontally across the screen. My screen resolution is all the way up and I already restarted it. The issue is kind of hard to explain but was wondering if anyone else had a similar issue or knew how to help. -Thanks Cam

Hi @willy4948 ,
I have looked into your issue about your HP Pavilion g6 Notebook PC and issues with the screen flickering or displaying dots. Here is a link to a document that will help you troubleshoot the image on screen flickers, has lines or distorted colors.
Have you connected the Notebook to a monitor? Here is a document on how to connect to a monitor if you need it.
Here is a document on overheating as some dust and debris might be causing the screen pixelation.
I hope something here helps you, please let me know how it goes.
Thanks.

Nope
One needs to press the home and sleep / wake keys together for the phone to reset
The other thing I could recommend
Let the battery run out and the phone completely "die"
It may take a day or two with it not being used
Then plug it in to charge and see if there is any change in behavior
If you cannot get this to work - you may need to bring it to an Apple store

My iphone 5 screen doesnt detect any sensor

My iphone 5 screen doesnt detect any sensor

A reset may help. Tap and hold the Home button and the On/Off button at the same time for approximately 10-15 seconds, until the Apple logo reappears. When the logo appears, release both buttons and await restart. No content will be affected.

My ipad 2 suddenly show red screen during start up and on ordinary screen show red colure fill the screen , I think it is hardware problem mostly screen. This problem didn't happen after fall or only accident ,what shall I do .

You could try a reset and see if that fixes it : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
If it doesn't then you could try restoring to your last backup and/or resetting back to factory defaults. But if it's a hardware issue then you will need to contact Apple.
