Subject: [TechAssist] Mitibushi VS 4544 Vertical collapse




Hi all
We got this unit in for a no picture sympton.  It would play for a while and
then lines through the picture and then no picture.  The customer hit the
set and it would come back on.  Upon checking the unit, We found that the
vertical had collapsed.  This was a housecall of many miles away and the
customer had originally said that it was an RCA and we only brought the RCA
stuff for a CTC169 fix.   Anyway, We will be going back.  Does anyone know
the location number as well as the part number of the vertical chip and if
there are any upgrades on this thing?  The help is greatly appreciated!!
Thanks
