Folks, I have an old Sony TV and an impatient customer that's driving me crazy! TV works perfectly and will continually do so for hours/days, until, sometimes, given a CH. Change or TV/Video Change...it then locks up, cannot change ch, again, sometimes with a perfect picture other times (customer claims) goes to blank screen w/no volume (could be 'Video' Mode). I've seen it do the former, lockup, only twice. So rarely, and with the back off, NEVER, that I can't begin to troubleshoot. When locked, TV remained locked until power was unplugged or cooled down cannot be sure, since I took time to remove back of set. HELP! Thanx, Clint Vanorsdell, DBA Video Van, Mass. Master Tech.
