Try tightening the screw on the lamp door. on mine the heat of the unit would loosen the contact which would shut the TV down.

Samsung 55" LED UN55D6003 Intermittently turns off and on...T/S help


DO NOT ATTEMPT ANY REPAIRS, CALL THE FACTORY PHONE NUMBER IN THE OWNERS MANUAL AND FIND OUT WHERE TO HAVE THE TV SERVICED, IF YOU ATTEMPT ANY REPAIRS THEY WILL VOID THE FACTORY WARRANTY. THIS IS CAUSED BY AN ELECTRICAL FAULT INSIDE THE TV, IT SHUTS DOWN AS A SAFETY FEATURE TO AVOID ANY FURTHER DAMAGE.

My t.v keeping shutting off by itself why


Outside of some pesky neighborhood kids "remote surfing" (standing on the street changing channels, volume, etc.with a remote control aimed through your window or similar), it is an indication of a fault.

The TV may be responding to an internal fault that is has detected and is shutting down to prevent further damage - or the fault is causing a condition inside that will not longer allow the TV to remain on. Either case will result in further damage if allowed to continue unchecked.

The TV should be tried with the remote receive "window" covered to prevent unwanted signals in to see if the set remains on. if it does,m you know that some stray signal is somehow getting into the TV. If it still shuts off, it should be checked out for faulty components.

I hope this helps - good luck!

TV on/off button keeps blinking/TV won't turn on


Try muting the sound on the tv, if it is a loose circuit the sound vibration can jiggle a connection and cause the tv to turn off as apart of its safety feature.

if the tv functions correctly while in mute then you now know it is a loose circuit.

if the tv continues to turn off even while in mute it is shutting down by the main power stand by safety feature, it may need a new main transformer.

if the muted sound solved the problem then unplug the tv and look in the back for the main transformer, the manufacturer usually places the main board on the box of the main speaker, the speaker could be vibrating a circuit loose from direct contact, the main transformer is heavy and would cause issues over the long run with high fadelity sound systems on big screen tv's. check solder points on main board.

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.

Poer supply is the cause of the shutdown and would need to be replaced. These cost around $150 bucks just in parts the labor you would need to find someone that knows just what there doing or you could wind up into the hundreds, Thanks

Tv shuts itself down


This is due to bad caps read here what a cap is www.badcaps.net see you tv is getting hot as normal but the caps cannot stand it any more thus shutting the tv down. The bad caps would be more or less in the power supply unit of this TV. So you can buy a new psu or get it repaired by a expert.

Tv shuts itself off


Look for the computer processor inside the TV. It needs to be cleaned. A can of compressed air will work. The processor is overheating and causing the tv to shut off. Look for the small fan that is supposed to keep the processor cool then remove the dust.

Good luck!
