Hi Guy`s,
I`m writing this post for help with a question about ISF calibration.
As many of you know already very few tube tv`s are perfect out of the box , and as such require a skilled “touch” to be perfect.
My question is , with so many tv`s on the market today , most have different user settings.
For example “Sony” has the program palette , which give us 4 variations of factory settings.
And many tv`s also have a setting which allows the user some control of picture tilt.
So with that said , how does ISF calibration happen , in a real world kind of way.
For example: I would think that the tv would be set on a neutral setting such as standard , and if a tv has a user tilt control that would also be set at the middle or neutral setting even if the picture is not straight.
After that has been done then the ISF tech , at least in my mind , should do his or her thing such as white balance , geometry ect.
I would not won`t to pay to have the picture tube straighten out just by using the user setting , I would rather prefer a yoke adjustment and while the back of the set is off do a thorough inspection of the set including proper placement of any magnets , a check of solder joints ( to make sure they are sound and no cold joints are evident ) and at the same time perform a manual focus and brightness adjustment ( if needed ).
Is what I have mentioned what takes place during an ISF calibration ?
Of course if the picture is straight with the factory setting at neutral then the focus and brightness could be check using an input generator and an optical comparator Any help with this would be appreciated , at some point I will either have my present set which is a Sony KV-32XBR200 or a new ( currently undecided brand and model) , calibrated and would like to know more about the whole process of ISF calibration.
I have checked ISF`s web site and it does state that on older models , such as my present set , a manual cutting of the wire or circuit must be don to disabled the VSM and that is fine.
Reason for calibration ? Too many channels with “jagged - edge” letters (even on the “movie” setting they are still evident) and general poor color due in large part to age.
What if I get a new set , you may ask , to make it the best it can be !!
Thank you very much for taking the time to read this rather long post , however all help would be grateful.
Happy Holidays to All !
Gary
