??? I want to help but need a little more info...I've been seeing a lot of 
vertical problems lately...a white line across the screen is no vertical sweep.

First try resoldering the pins on the vertical output IC...it's a large IC 
mounted on a heatsink..but it's a good idea to look closely at all solder 
connections...this is a common problem. Some sets will power down if there's a 
short in the vertical output stage...on a philips I recently worked on it would 
try to power on then shut off so I pulled out the vertical output IC and then 
the set would power on...

Another common problem are the caps next to the IC there's usually 3-4 caps...I 
most always just replace them they are cheap to replace and prevent a call 

As to that white resistor what kind of set is this?  Sony uses those white 
fusiable resistors and I don't know what horz claps is?

TV powers on fine but has a solid white line across the screen from left to 
right or from right to left, has a resistor R14509 that is white in color I 
know it horizontal claps. also need to know value of resistor.
 Now it power up and then shut down what could it be.
