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?

    Purchased Samsung LN-T4042H in April. Recently started turning off for no reason, and won't turn on by pressing on/off button. You sometimes need to unplug and will turn on after plugging back in. Today, it turns off for no reason and will turn itself back on for no reason. We have AT&T U-Verse Cable. We're wondering if that is a factor???

    MY MODEL # IS HLR4667WX/XAA. IT CURRENTLY VIBRATES AND MAKES A VACUUMING SOUND. IT DOESNT TURN ON EITHER. I REPLACED THE ORIGINAL LAMP MAYBE 2 YEARS AGO. I CHECKED THE CURRENT LAMP AND IT IS NOT BLOWN. WHAT COULD MY PROBLEM BE?

    This the exact problem I'm having. No noise but it is turning off randomly and sometimes won't turn back on. It's now getting worse.

    I replaced the bulb about two months ago and now my TV suddenly shuts off. I think it has to do with the temperature. IT needs to cool down before it will turn back on.

    When I replaced the bulb, the original bulb was no longer provided. They gave me a replacement part from Samsung Parts that was to supersede the original lamp. I think the newer lamp is of higher wattage and produces more heat.

    Does anyone know if this is in fact the issue and can recommend a fix.

    I have had TV several years and all of a sudden it is randomly turning off. I can turn it back on, but it goes off again within 15 minutes. it will do that about 5 times and then last for a couple of hours before repeating this. i have not replaced bulb. i need to know if it's the bulb, although from the comments on your web page, that didn't seem to fix it. i don't have a problem thus far with sounds and vibrating.

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.

Hello ma'am, hi, looks like the tv has problems with the power supply board, parts inside get to fail slowly, those are likely resistors, and capacitors, and active parts like transistor gets to go leaking, eventually they will be permanently to fail. so have it checked by a tech guy.

Dear dreadtrainer;

It sounds like your Lamp is going bad. The part # B96-01472A. Go to internet (like Google), enter Model # and Lamp toget your best price. To replace the lamp is easy, look at your 'owner's manual".

Good luck, Big Irish.

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.
