half a screen help

(1/13) > >>

kjn4685:
I have a elenco oscilloscope 30 mHz oscilloscope model #s-1325. I was testing a 5v power rail. An then I noticed that the scope had a half a screen. I have tested everything I know how.
Can anybody help me figure out what's going on.
Lou I would appreciate any help
Sorry they out of order.
 I have a problem the silk screen on the board and the parts list are different. Does someone have some ideas what's going on.

Pics required.
Do you have a manual or schematic?

Psi:
Maybe you've lost one of the deflection coils.
Either bad connection or blown driver.

tautech:
BUMP
OP has attached a pic and schematics.

It is Electrostatic deflection---guess "coils" was a typo!
