There is a thermal sensor and venting on that unit, that if blocked with dust, would send the thermal sensor higher than normal. I'd start there with cleaning the vents and filters then changing the sensor if needed...

Samsung hl-s5087w.... Tv is 4.5 years old, and is about 200 hours into its 3rd bulb. Yesterday, very similar to when the bulbs burnt out, it shut off. I thought that it may be getting too hot, so after it...


Above the light is a temp sensor with a blue and white wire plug. This sensor is the problem for all these shut downs in my opinion. Pull out plug and jump it with a wire or paper clip bypassing sensor. Tv should work now!!!!

I have a Panasonic PT-50DL54J DLP projection TV. It suffers from a shut down problem. Shortly after powering up, the TV shuts off, and the front LED flashes red 6 times. At this point, the TV will not...


I have similar problems. I removed the back panel and use compressed air to blow out all the dust from all the components. Just remember not to blow into the main fan on the right as that is the one cooling the lamp. I don't know for sure if this is the only problem.
Dust built up caused heat built up on the components.

Have a mitsu wd-52631 - get message "tv will shut down in a few seconds - chk for air flow blockage" then shuts down - wil turn on after sit for several hours. No blockage evident.


Well....the reason you are getting an "airflow message" is that there is a thermal sensor on the BACK of the lamp cage, and the connections on it get to be "intermittent" after awhile...and when this happens...the computer thinks that the lamp is overheating due to a dirty filter or fan--and shuts down the set.

It is a small, white plastic sensor, with 2 wires on it, that go to a connector and it has a black and red wire(usually) in a twisted pair that connects to the sensor connector. The connectors need to be REMOVED and the sensor HARD-WIRED (directly connected to) the other pair of wires. IF you have done some electrical work before...this is easy. You only need about 3" of spare wire to patch in between the sensor and the other connector, after you cut the connectors off. BUT...if you do NOT have repair experience...I suggest you call a COMPETENT, FAIR tv shop in your area, if you do not have a service plan...and tell them you have a mits. set that needs the "airflow sensor problem" repaired . this CAN be done -in-home, in about an hour or less, and for under 300, including service call.

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!
