I have a mitsubishi model wd-52527 that will not turn on?

Question

status light blinks yellow, i have removed and cleaned filter but did not help

Answer 1

I hope this isn't the one I just put the rebuilt chassis assembly into on friday.

Status flashing at about one second intervals should be the vent door all right.  Make sure the door is reinstalled correctly--it has little tabs on the bottom that have to be inserted otherwise the switch will not fully engaged.

Now the bad news--probably a fan that is not running---with the set on and fully booted hold the device and menu keys down for 8 - 10 seconds then count the 2 digit error code flashed green.  A fan code is usually 34 or something like that.  Call your local service center with the error number and model and they can research it and estimate it if you dont have an extended service contract.
