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

I had a Magnavox using the la7672 jungle were the crystal would
intermittantly change freq causing the Horizont to go to about 60Khz.  It
would pop in and out.  When the pic was small it was a good pic, good
geometry, just small.  Of course the HOT would fail shortly...
