Question about Samsung LN40B750 40 in. LCD HDTV

1 Answer

Trouble turning tv on.

Recently I hooked my computer to my tv, and about week later the tv started gettin a delay in turning on. Well last night at 11:15 pm i went to turn tv on and it's 10:00 am now, and it still hasn't turned on. I can here what seems to me like it's attempting to turn on. It's just a real annoying click like a huge clock. Sometime like clicking slows down, and speeds up, but right now it's at a steady pace. I've unplugged it twice already. Each time I turned it off the clicking pursisted for a couple of seconds. I turned the tv off the 1st time for about 10 mins. The 2nd time for about an hour, but I still get nothing but the click. Can you tell me how to fix it please, because it's driving me crazy lol?

Purchased a 42-Screen "flickers"

Inverter Board going bad or loose plug, then the backlight board will fail within 3-4 weeks later. Good thing you saved a few hundred on the x-warranty, BB won't do a damned thing for you regardless; it's discontinued & they lie about their 'replacement vouchers'.
A 12" bi-metal blade is recommended for your reciprocating saw so that you can cut this thing into small enough pieces for your trash collection.

TV wont turn on, makes buzzing noise and shuts off

I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.
