Steve, Phillip, The 203 problem you posted and we commented on ... Having a 203
on the bench with what seems to be the same problem. We found the 3.7 volt
regulator on the uprite AV input board was loading the 12 volt source. The
voltage was down to about 2 volts on the load side. We desoldered the regualtor
and the set came on and worked. Resolder the regulator set worked. Tried unit
several times with regulator connected and would fail or work .. Just never new
when it would or would not come on... We don't know if the regulator is the
problem or something on the board is a problem. At this time the darn thing is
working with regulator resoldered??? Wayne.. Tv Service Company, Lexington,S.C.
