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.

If the lamp light is on, it is time to replace the lamp module, which is behind the front panel below the screen.

SOURCE: tv wont stay on .

When you changed the lamp did you clean the "lamp temp sensor"? When you removed the lamp housing from its cradle, you can access it from where lamp goes. It can be cleaned with a Q-tip.

Also, there is a little blue safety switch that is located on bottom right of the light engine tray. It MUST be in the DOWN position when the TV back is reattached to TV. You can use tape to hold it in the DOWN position while attaching the back of set.

Also after replacing your lamp did you reset the lamp life?, You can do this by:
1-TV off
2-press mute+1+8+2+Power. This will access factory settings.
3-scroll to "Options". Press right arrow to next menu. scroll to "lamp life" hit right arrow and click reset.
4-power off.

That resets the lamp life hour meter.

Well my mom was watching tv and it just shut off so then my mom turned it back on thinking she might have hit the power button accidentally. But when she turns it on it started blinking the green light for...


The flashing light red power light should only stay while the fan cool down for about 1 minute after a power off (remember to always wait before unplugging the TV so the lamp can cool down with the fan). Does that flashing start right away after plugging back the TV after an hour of letting it without AC power.

The red light should flash no longer than 10 sec. This prepare the light to be turned on. If all is OK the green should stay (no longer flashing) and the sound and picture come on.

As for the lamp flashing, i bet it's only 1 time each 5 sec? Or do it group many rapid flash each 5 sec?

Things that can be wrong:
-the fan lamp

-the lamp is not proprely inserted (wait an hour before manipulating it to be sure it cooled down, and use glove to not put body oil on it).

-Lamps is defective and is not operating properly so you can't get to the usual on screen message that recommend to change the lamp.

Temp light flashes tried unplugging it for a few minutes turned it on tries to power up but then power , lamp , temp lights flash for a few seconds then it shuts down and temp light stays on


It sounds like you have a thermal issue. The TV is getting too hot or the Thermal Fuse is bad. The thermal fuse detects the temperature in the TV and tells the TV to shut down if it thinks it is too hot. Most likely caused by poor ventilation or clogged fans from household dust. Try moving TV away from wall or cabinet first, if this does not fix the problem, clean ALL the fans in the TV. If problem still persists, replace the thermal fuse.

The lamp may be starting to go, the symptoms you describe are classic warning signs. You could unplug tv let it cool down and check lamp most likely the glass will not look clear maybe a little milky or smoky in areas..dead give away.

Lamp light blinks 3 times shuts down


The CLS problem. Im thinking that at least you made a visual inspection of the power suply and the capacitors around it. Then if everything normal in the area then the microdisplay (inside the ligth engine) can be damaged. (when the tv is working normally the microdisplay sends a pulse to turn on ballast and lamp finally.

The sweetkyman: when the fan is bad th tv shuts down imm. (if you unplug the fan when the tv is working normal the computer detects the overcurrent system works and shuts down the set) when a fan is all dirty and tons of dust on it the tv tends to work but after some hours the tv shuts down.
