??? 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 back. 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? --- On Wed, 8/1/12, Anthony Clayton <tcccjc@xxxxxxxxxxxxx> wrote: From: Anthony Clayton <tcccjc@xxxxxxxxxxxxx> Subject: [tvservice] tvservice@xxxxxxxxxxxxx To: tvservice@xxxxxxxxxxxxx Date: Wednesday, August 1, 2012, 3:22 PM 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.
