Power is correctly hooked up with standby light lit. When turned on the normal startup with the Toshiba ET1 logo and then to the input. Both the bulb and lcds are working fine but about 3-5 seconds after the inputs are up on the screen the buld goes out and the lights over the standby and lamp are solid red with the fan running in cooldown. This will happen each time I attempt to start up the projector. However if I start up the prjector again right after the fan turns off and returns to standby the time before the bulb shuts off again will decrease to before the Toshiba ET1 logo appears. The only thing I can think of is maybe a thermal switch problem but all fans seem to be running and the filter is clean. If anyone knows how to go about fixing on a minimal budget please leave me feed back. This is my first time using this site and I thank you ahead of time for your support. -John
Most fans have a sense line to detect the fan is working properly, Possible the sense circuit has failed. The unit should not start if it thinks the fans are not running. Possible thermal problem with the sense circuit, since your unit starts up then stops.

Same issue here. I kept plugging in the TV and it would flash the logo and go black. I disconnected the LED line from the power board, plugged the TV back in and the LED's all lite up and got great picture. Turned it off and on a few times with the power switch with no problem. Left it alone about an hour, came back, got the same symptoms all over again, Flash then nothing.
I changed out the Power Supply board....same issue, Flash of logo and black screen. Probably going to heave ho the set.
Check the circuit boards to see if any have failed. They are small cylindrical objects. If the tops of any of these are bulged instead of flat then they are bad and board will have to be replaced. Hope this helps.
