Toshiba VTV-1415

[Jack00]

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 drops
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.

IT SOUNDS LIKE IT'S FUCKED UP.

That's because those motherfuckers are made by Orion motherfuckin Electric
which makes fucked up motherfuckers.

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

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

I don't recognise the model, but I've seen this problem caused by a
dry joint at a low value resistor in the horizontal yoke circuit.
There is also an electrolytic capacitor near the jungle IC that can
cause this problem on some chassis. Otherwise I'd change all the
electros near the vertical output IC, and reflow all the solder joints
in that area.

Most of the time, this from electrolytic capacitors failing in the
vertical deflection area.

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

Sorry, I meant vertical yoke circuit.
