so would it be a fault in the horizontal stage thats causing it to be dead?? will it not be more of a psu fault??

It's a common failure on this set.

oh ok, does the fault go hand in hand with the psu blowing up then?? does it give the symptons of totally dead?? thanks for your help.

The red light comes on then go's off, usually. The horizontal is part of the power supply. The primary feeds the secondary where horizontal is formed.
