LG 50PG20-UA No picture, good sound.

Troubleshooting TVs and Video Sources - Badcaps Forums - www.badcaps.net
I have a LG 50PG20-UA and I have no picture, sound is fine. Visual inspection shows no sign of trouble on the boards. If I remove the upper y-buff and I get the bottom half of the screen to go white, bright for a few seconds, then about half as bright. Upper y-buff back in and the screen gets nothing. Is this most likely a bad upper y-buff and is it worth ordering that card to see if it fixes it?

Thanks
