Watching tv and it turn off

My tv shut off by itself what can i do ....it make a little noise before it shut off

My TV started turning on and off by itself and has become more frequent with time to the point where it is a constant. It will turn off and come right back on, but when it does, it changes to channel 3. If I manually turn it off and then back on, it will return to the proper channel it was on before I shut it off.  There seems to be a large "static" noise just before it does it's thing.  Any Ideas?

    Thanks for getting back to me Dan..The make and model number is as follows:  27" Phillips/Magnavox (flat screen) model number: 27RF505125.
    As far as the other question you had, it gets increasingly worse as it remains on.  Used to happen once or twice after being on for hours. Now, it starts in less than 5 minutes after it has been on. 
     Thanks again for your time,
     Daniel G

Please update this with a make and model number. WIthout that information there is little assistance I can provide. Also, does this occur all the time or only after the set has been on for a while?
Thanks,
Dan

    Lets start with the simple stuff. This sounds like it could be just a bad connection on the board. If you have any soldering experience, open up the set and resolder any connection that looks grainy or has rings. Report back here with your findings. In the meantime, I'll lopk up your model to see if there are any common parts failures that would account for this. (I know some, but certain models are prone to some problems.)

Did my tv just blow up?


Yes, I think you have lost the bulb and maybe the color wheel is on the way out too. But try a bulb first. If the old one has a broken "glass tube" in the center--be assured it is bad.

When turning on the TV, I hear a banging/grinding sound.


Hi,

If you hear a grinding,whirling,spining or buzzing sound, that sounds to me like the COLOR WHEEL,the reason for that is because your color wheel spins at 5,000 rpms(revolution per minute) and something that modifies the balance of the disc can cause different things,Unfortionatelly the only way to check that the color wheel is working properlyis you need to check it out physically

I did some research and I found the color wheel at DM;http://www.discount-merchant.com/Samsung-Replacement-Color-Wheel-HLS-HLT-Series-p/samsungcolor_wheel_bp96-01579a.htm?CLICK=52978

Please keep us posted.
