Epson projector temperature sensor malfunction

This happened after I transported the projector on a wheeled cart. It was protected with bubble plastic but it still hit some obstacles so I'm guessing a sensor became loose. I've already disassembled and reassembled the auto-iris and the sliding filter. All seemed to be good.

If the problem is the sensor: I've seen in comments that dropping it from about 3 feet over a soft surface, top facing up, should reposition the temperature sensor, but I'd rather find this sensor and reposition it myself.

THANKS a lot for sharing this tip which saved me from becoming crazy trying to change the thermistors which weren't the problem. Thanks to this video, I hope using my beamer 8 years more !!!

Hi, my Epson projector is beeping after I cleaned the dust out, I’ve been told it could be that the sensor battery needs replacing or sensor malfunction, are the sensors always near the bulb?

Boa tarde, prezado Thiago. Tenho um Epson Powerlite 3510, que, dias atrás passou a piscar o led de temperatura toda vez que o ligo. Aí, alguns segundos depois ele desliga e fica um dos coolers (provavelmente o da lâmpada) à toda velocidade durante uns dois minutos.
Detalhe que o tenho desde o início de 2017, sem nenhum problema. É isso começou quando eu estava assistindo a um filme, dias atrás. Ele simplesmente desligou, ficou com o cooler à toda, e depois, só faz ligar durante alguns segundos, a lâmpada até acende. Aí dá o aviso de temperatura, se desliga e o cooler entra em ação.
Você teria ideia de onde eu poderia conseguir o manual de serviço dele? Eu queria verificar se o problema pode estar em algum dos outros coolers, porque notei que tem pouca corrente de ar na entrada do filtro (que está limpo, inclusive, pouco ar é puxado pra dentro, mesmo com o filtro retirado).
Queria ver isso antes de enviar para uma autorizada, pois moro em Sergipe e quando penso no frete... Agradeço desde então.

Sorry! Do I miss the tip? I have the same problem, but do not see your solution!

[vipulyadav]

I have facing same, what the solution for this ?

[kgerakopoulos]

probably sensor problem, I have read that if you cut the sensor and replace it with a 200ohm resistor should do the work

My brand new in a box Epson 3800 lasted less than 3 hrs of lamp time. The fans didn't go into high speed during shutdown like my old Optoma HD32 projector did (which is still working after 16 yrs, BTW - same bulb). I don't know if this is normal or not, as it's my first Epson projector. However, on the 4th time I turned it on (day 2 of ownership), the fans start normally but then go into high speed mode (no lamp) after about 5 seconds and the temp light flashes orange, like it's overheating. It's not overheating, it's ice cold in an 18ºC room (no lamp on). I suspect a faulty temp sensor/thermistor after doing a bit of reading. This does not instill my faith in Epson. The picture was mind blowing though, while it lasted, so I'll give them another shot.
