Hello All--    Mea Culpa Mea Culpa---Have found cause of fault----this set
has 2 small boards that at first looked like interface boards to hook up the
ribbons of the screen to ballast board----they are not interfaces but scan
driver boards----I mistakenly installed the 2 boards in the wrong
order----alll other boards in the set are installed with most of their
components facing out whereas these 2 boards have their comp facing
in----very interesting symptoms  and thanks Phil for your always appreciated
efforts-----there doesn't seem to be any accomadation in the menu for
inverting the screen    thanks again  Peter   Keith's Stereo

Hello All, Interesting symptoms. This set came into our shop to be
dismantled for a cleaning after a house fire. It was working just fine.
After being dismantled, chem cleaned and then re-assembled, we have a
picture that is inverted (upside down), vertical centering is about 1/3 from
the bottom and the writing appears to be reversed. Anyone seen anything like
this? Don't see any accomadation for reversal or inversion of pix. Wondering
whether eeprom corruption might cause this kind of  symptom. I'd be an
inquiring mind if I knew what questions to ask     HELP !!!!!
