When I switch this television set on it works fine but after 10
minutes there is field collapse and the sound is ok. I heard it has
an Orion chassis. Does anyone know for which model? What normally
goes wrong here? Thanks

By "field collapse" do you mean loss of vertical deflection (picture

to a single line across the screen from right to left) ?

Vertical problems were frequent on Toshiba chassis sets for a number of
years in the 90's and into the 2000's.

Yes, loss of vertical deflection. What could be wrong?


Usually, bad solder connections at the vertical output IC, and potentially a
SLEW of bad capacitors.
