It's a samsung LTM 1755 17" LCD HDTV. When I turn it on it takes like 5 minutes to turn on, and when I change the channel it takes about 5 minutes to change. Also the sound does not work, I checked the power plug and all external factors, and I'm convinced it's an internal problem. Anyone know what the problem might be? And if you can give me an estimate on how much it will cost to repair, I would would appreciate it.
Thanks.
Edit: It just happened, the previous time I used the TV it worked fine.
