Friends,
This projection set is about four years old. When you turn it on, you
would think all three CRT's are bad, like a gassy CRT. Have run into
three of four of these (in various models). The symptom is caused by an
open 120K resistor on EACH CRT board. (The board is 9-1303-6. The
resistor is R5102.)
The first one cost me the price of a new blue CRT before I found the open
resistor.
I write this to inform those of you who haven't seen this before and to
ask a question of those who have. What causes the resistor to open up?
Have never had one come back, but it makes me wonder.
