Thanks but, Unfortunately this appears to be an all Toshiba made chassis
(TAC0245, N2ES series). Haven't had time to get back to this set today.

Peter
I found this in my notes, maybe will help you fix your set
27A43 (Orion) chassis M3N426
Horizontal size narrow and wavy interference in picture
Replace D603 15 volt Zener diode #AD300670/MTZJ15B
also repair circuit trace anode D603 to IC601 pin 57 (chassis ground)
may need to adjust Hor Size in service menu
Service menu access hold volume down on tv and 9 on remote
select parameters with ch+- and adjust values with vol+-
power off to save and exit menu
When the zener shorts it opens the ground between these 2 parts D603 anode
to IC601 pin 57
The open ground causes the wavy type interference
but the shorted zener D603 causes the horizontal width to pull in about 3-4
inches each side
