Hi Wonderwoman1, first of all, do you look anything like her?
Your television could be a few things, it could be as simple as a bad solder joint, did it go all of a sudden or has it been playing up for a while?
Does it make a Ticking sound? i would want you turn it on again for any length of time as it might make matters worse.
If you know anyone might be worth getting them to take a look, but I would go for someone that you know or a recomendation and ask if they charge to look, I think a most people will charge to look and then take it off ht ebill if you go ahead.
Depends on what size it is, if its a small portable, might just be worth getting a new one.
I presume you don't have an extendede warentee on it?
Steve
