[TechAssist] Re: Toshiba TP48D90 Picture Zooms In/Out

Jeff,

It sounds a bit like the set is  blooming from your description. Does the
picture focus change when it does it?
Have you checked the FBT and splitter by chance.
Maybe even an intermittent problem with the G2/Focus divider.
A long shot I know but its about all I could think of when I saw your
symptom.

Make : Toshiba
Model : TP48D90
Problem : Interesting problem.....Picture will zoom out a few inches
intermittently on all 4 sides...almost like a zoom/magnify function.May do
it slowly or real fast in a fluttering type effect.  Not vibration
sensitive..tapping on the chassis has no effect

Convergence stays solid when this happens.  Changed the STK's to be sure as
the green parameters effect entire image.

Pulled the 3 chassis boards and went over real well....only a couple
marginal connections.

Any bulletins or notes that may apply?
