When i turn my tv on i hear sound but no picture.then about 2 minutes later the picture comes on then goes off comes on then goes off it does this for about 5 mintues then the picture stayed on.in the last week the picture comes and goes more often .last about 10 seconds between on and off .i have notice more red in my picture.tv repair man told me sony does this cause the tube is going bad. is he telling the truth or is it something else?
The on and off conditions is repairable and is not the tube,you should have it check out for loose conections and try not to use it or it will go bad for good and the repair will become expensive,Check power supply,horizontal driver transformer and crt board,If you are not familiar with tv service be safe and call for help.

The power button turns on but there is no sound or picture. Within seconds the tv comes on for a second and then there is a blank screen. It repeatedly does this as if it is trying to warm up but doesn't get any better.
I have a sony HD WEGA 50in. That has just started having the picture go off and on,pic stays off for about a minute,stays on for a couplke and then repeats for as long as the tv is on...
