My TV [3D LED Bravia EX720 40 inch] suddenly is showing a vertical red line of stuck pixel from top to bottom of the screen??? Is it permanent or there is any method to solve this problem…???
umm I never had a 3D tv however I think you will find in the 3D tv menu an option of the screen resolution and dimensions (wide and height) things like that you can expand it more to top I think that will fix the issue
not recommended action
perhaps something is not well connected or power problem? applying pressure may fix the connection problem
There's a great article here:
Especially look at the resources at the end of the article. There appear to be several ways to do this:
* Manually through rubbing the screen somehow as described by the article.
* Using software to cycle the pixels through the screen. Hook up a laptop to the tv to do this. Most TVs these days should accept a hook up from the auxiliary video output of your laptop. It might mean just finding the right cable.
* Use a YouTube video to cycle through the pixel colors. Search for the keywords "stuck pixel" without the quotes of course. There are a bunch of them. Some lasting 8 hours or more. They generally get overwhelmingly positive reviews.
* There even used to to be hardware you could buy to hook to a television directly. It was called PixelTuneup. It doesn't appear to be manufactured anymore although if you want to order 10 from Alibaba, the apparently Chinese factory will make them for you: http://www.alibaba.com/product-free/110005683/PixelTuneup.html. It sounds like a business opportunity...
Just guessing, but I think that is something you will have to hit the manufacturer up about. Usually it is only one Pixel that is bad and it shows as a little dot. But not sure if it could happen as a whole column.
