[edupc]

hi

my Bush Tv powers on to stand by, and when you want it to light up the tube it can't, but u will be hearing the volume on the speaker, but no picture.
the problem started by the tube changing colors while watching, then goes blank if you watch it a long time, but now no display. please someone help me.

if you want people to help you solve the problem it may be an idea to at least give them a clue as to what the model number is??????????
