No picture just vertical colored lines
turned on my Sony bravia 42" tv and immediately the whole scree was covered with vertical lines about a pixel or two in width. the color of the lines changed as the image changed. Could it be that the firmware got clobbered and is there a way to reload the software? Had a problem with my 52" Sony years ago and they sent me a thumb drive with a software update that fixed the problem. Called Sony they were no help!
Is this a good question?
