In another thread, there was a problem with a ST30 panel ( a vertical line running on one side of the screen) owned by a person. Good that the set was under 3 year warranty and so he got a new ST50.
My question is - why are these lines start coming after few hours of usage ? Are they genuine manufaturing defects or defects shown due to the way the TV was used ?.
My intent in asking this question is - As a user, can that be prevented by following a particular way of using it ? For example, are those panel related defects start coming out due to erratic power supply or any other external causes or due to some way of using the TV ? If it is due to some external causes (either the by the usage or other causes), then we can take proper steps so that we use the TV in a better way (for example - adding surge protector or anything for the matter)
The very reason for posting this post is that I owned an LED TV before and just after 1 year, a vertical line started coming on the right side of the panel. Unfortunately it was out of warranty. The total hours of usage was around 1100. Now I want to be precautious with my new ST50.
