Now this may be a fluke but.... after reading some other posts about the missing lines problem, I got my VR5000 out of hibernation and connected up 12volt supply and it works but the display was still bad. I left it going in a corner of the garage and much to my surprise by the next afternoon some of the missing display lines had returned. After three days of running continuously even more lines have come back. Don't ask me why - I can't explain it. If I switch it to the preset HF broadcast station screen it's easy to see how much has returned - prior to this pic all of the left hand half of the screen was blank and most of the right hand side had many line missing - now they are coming back and 'regenerating' slowly across to the left - is there some hope...... wait'n'see !
