I had a problem with my PowerShot A300 where the LCD screen looked as if the image was "melted" with a reddish tone. I checked many different websites and finally got to a link on the http://www.usa.canon.com/consumer/controller?act=PgComSmModDisplayAct&fcategoryid=257&modelid=13390&keycode=2112&id=29819 website and indicated to contact the company directly to send unit in to be repaired.

Problem: Internal wiring may become disconnected, especially if the affected products are stored or used in high-temperature and high-humidity environments

Line top to bottom of screen 4 inches from left side; whole area distorted. appears after tv is on 15 minutes. does not go away. tv is 2-3 years old. was not dropped.


A TV does not to be dropped to get errors. The screen is build up with a a few million pixels. they are switched on and of in lines and rows.
Bundles of rows and bundles of lines have a combined "switcher" If one bundle gets a poor supply (bad contact or defective electronics) a band of pixels will act different or not at all.
I'm afraid it is a normal defect and you need a tech to solve the problem.
Before you order someone to repair, ask what it will cost, because in 3 years TV sets became much cheaper. Perhaps a new one is cheaper than a repair.

I have a red dot on a Coby TF-TV2001. What can I do to repair this?


If you mean you have a pixel that is stuck on and is always red, there's nothing you can do. The only cure is to replace the display. LCD displays sometimes will have a pixel (sometimes several pixels) that doesn't work properly. The manufacturers know this, and as long the display falls within their specifications for what's acceptable, they don't see anything wrong. These specs include the total number of bad pixels, the number of bad pixels that can be clustered together, and where they can be on the display. If you have just one or only a few bad spots, they won't do anything for you. If other problems develop, such as a whole row or column goes bad or a section of the display fails, then you can see about having them fix it if the warranty is still in effect.

My lg lcd got a pink vertical line on its right hand side and it is getting bright day by day .my lcd is LG FLATRON L177WSB. is any solution pls get me out of dis ..................


What you have is a row of "stuck" pixels. Do a google search for a utility that will "repair stuck pixels" I have used them with very limited success. Your chances are better if it is just one or two but you have whole row. That says to me it's a bad transistor somewhere.
Here is a video that shows how the 'unsticking" process works with a web link.

You are probably looking at buying a new screen.

Black line (strip of pixels not working) horizontal across screen


If a whole line of pixels is dark, you've got a bad transistor in what's called a "Passive Matrix" display. For your future purchasing decisions, while an "Active Matrix" display costs a little more, it has individual transistors for each pixel, rather than one per row and column, so when a transistor goes bad, it only turns one pixel black rather than a whole row or column.

Black spots appeared on 17" LCD Monitor-SyncMaster740N


you might have what you call "dead pixels" or a "stuck pixel" try a simple test like this one now it is not the most creative one, but it does help to see if that is the case. u might be able to Fix a STUCK pixel, but unfortunately you can not fix a "DEAD pixel" simply because it is DEAD.
try this website for simple fix instructions.
if is dead pixel what you have, if u can live with it, great, if not , it might be a good reason to get yourself an another monitor.

Good luck

Two light lines have just appeared


Your driver transistors are failing on those "Rows" of Pixels.. a common problem .. you could try "Pixel Reviver" software from here http://www.wikihow.com/Fix-a-Stuck-Pixel-on-an-LCD-Monitor see if that helps.. but it possibly is on the way out sorry..
