Thought I would pick the brain trust on this one and see if any of you had a
better explanation for this than I could come up with.
On most of the large PTV's I repair, after cleaning the optics and returning
the set to normal operating condition I have often had my customers take
issue with the flickering effect noticeable on fine graphics, such as a
sattelite reciever menu or the emblems on some stations, or the sports
scores on a footy game.
The flickering is most noticeable on a white line, for example, running
horizontally where the line appears to be between two scanning lines. I'm
sure you all know what I'm referring to. It can also be seen to a lesser
degree on say a 27" direct view set.
I can usually explain this away to most customers for what it is, a result
of the number of scanning lines being only 525 as well as it being
interlaced scanning,( at least thats what I put it down to....maybe I'm
wrong) as it is not noticeable when watching a normal picture without fine
graphics or text, but my lawyer wannabe customer on this particular set is
threatening legal action and has, of course, contacted his credit card
company to fight the charge as a result of the completely "inadequate
picture quality"
For reference, this is a 7 year old 45" mitsubishi. BTW, the picture looks a
million bucks considering the age of the set.
My question is this.. are any of you aware of a website, for example, where
this issue is listed and explained, perhaps better than I can explain, in a
laymans format that anyone could understand?
I thought some of the sites where people are encouraged to enter their
service menus and really screw their sets up might have a reference to this
in terms of extolling the virtues of HDTV as opposed to NTSC but have had no
luck.
I simply want to have a little more ammunition for the credit card company
when they call than me other than me simply saying its the way it is on the
setup he's got and thats it.
I would also be interested to hear of any suggestions, tips, stories or
amusing anecdotes with regard to how the rest of you handle these type of
customers. You know the kind.......zero to dxxkhead in less than a minute.
Thanks for any advice.
