Westinghouse TV no picture : Strip or fix?

[JesusJones]

OK so i tried it again this time with intent of leaving it on and nothing. No flash no nothing. Back to dead. This is bothering me


The width control. This resistor is not functioning properly I think.
With my ohm meter hooked up to it set on 2000k I can get it to read zero And i can get it to read Nothing its either zero up to 12k Then It says there is no connection.And this happens within 1/8 of a turn. After turning the TV off I actually got some picture to show up. I wouldn't call it picture though it was just light.

My question now is. Would this variable resistor screw the whole thing up. Cause it kinda seems like it did.(it is the width control one hooked up to horiz output tube.)

SO will it need cleaning or will I need a whole new one.And if I do need a new one, ElectroKing you will have to tell me what it is I cannot make it out from the schematic.
Thanx
