Samsung HLR4667WX/XAA television keeps turning off

46" HDtv large screen samsung television keeps turning off by itself. I can turn it back on and sometimes it stays on, sometimes it doesn't. The little green lamp light on the front flashes too. Today there was a noise when it happened that sounded like a vacuum cleaner running in the rear of the tv. It also made a siren sound. What could it be? Do you think it will be expensive to fix or can I do it myself?

If it's making a loud vibrating sound it's due to the color wheel shattering. easy to replace sits on top of light engine.

Cracked 46 inch screen on my Samsung tv. Where can I get a good deal on replacement? Or can it be repaired? Please help Model number is LS46BHPNB/XAA

You can go to Encompass or J&J electronics for the Panel. But If you have never replaced a Panel before, it is best left up to a trained Samsung tech.

Samsung LCD 40 inch LNT4061

It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thanks for using FIXYA, big IRISH.
