Tv cuts off after few seconds

check that the lamp fan is working

you need a new power supply unit these after some time get old and start over heating causing the tv to heat up intermediately if you take it to a repair shop and have that replaced it will be like new again

In the 65" TVS there are 4 or more fans One of these is not functioning Probably the one over the power supply itself This will cause it to heat very quickly and shut down in a matter of about 20 seconds.

only way to find out which fan is not working isw to remove the back.

please rate my help++++Thanks for using FIXYA

Check the circuit for the draft inducer fan motor. The centrifugal switch in the motor may be shutting down. This stops power to the gas valve.

They had some stupid problems with these sets---If you know how to remove the lamp---it is customer replaceable--take it out and examine it. Shut set off first and wait a few minutes for the lamp fan to turn off. Unplug set and locate and remove lamp. Some of these sets had a lamp (it is in a cartridge like a box) that they covered openings on the housing with a screen like material (like window screen). One side of the lamp has a fairly small narrow strip of this and it blocks up with dust from the fan which is trying to keep it cool---if the screen is blocked up you will see it; Do not touch the face of the lamp when you handle it--if you find yours has a screen like material--clean it off with a brush and put it back--the later replacement version of this lamp has a screen that is coarse and does not block up with dust---on a couple of these I removed the blocked up screen material until I could get the newer lamp so the customer could continue to use it--if cleaning the dirt off works you may have to do it from time to time--depends on environment--the fan tends to pull dust and such out of the air and right into the lamp---

I do this for free here so if this does help you give me a vote here. If you have questions or need help contact me here.

most rear projectors will turn themselves off whenever the lamp is dead. what we call protective mode. in this case the yellow light may be for the lamp. otherwise check if all the fan are working properly.
But MAKE SURE you let sufficient time for the tv to cool off before unplugging the main.

hope this helps

This maybe a McGuyver thing. Last thing you want to do is block the air flow to cool down your TV set. I would blow out all the dust, get a HEPA filter for house ventilation, get a computer cooling fan. Cut and put the filter in front of the fan, make the fan blow in to the TV vent in the back, that way it blows clean air in and keeps dirty air out. I hope that's one good idea.

Good Day;

If you have a WD-52525 Model TV and the the screen displays "air flow problem" change the sensor. There's not a positive way to check device, just replace it, trust me. IF your TV is a different Model MIT'S has a recall on those certain Models. REPLACE.

Good Luck, big IRISH.

There is a software patch that increases the cut off temperature you may get this at Loewe Website. Quick fix is reverse one of the fans on the back of the set this gives a through flow of air rather than all fans blowing into the set.

Call Mitsubishi. They have extended their warranties on certain DLP's, because of a faulty thermal sensor. I just had mine fixed at no cost by an authorized service provider.
