You probably gave too much information. Don't say it works sometimes and
other times not and you can "correct" it. Turn it on and when it's in that mode,
leave it that way until the repair guy comes or you have to prove it to someone.
The tv is not suppose to work like that, so it is broken already. No need to
try to fudge the situation, just be more forceful and ask for their supervisor etc...
until you are satsified with the results.
