@@Electronicssystem I have a hitachi CP-EX251N projector. After testing, the Thermal switch works well (I desoldered and checked it). My problem is that the projector does not report any error with LEDs (neither lamp nor overheating). After switching on, the green LED starts flashing. All fans start and the lamp lights up. The image appears and it randomly lasts longer or shorter, a message about entering the standby mode appears (as if I had pressed the on / standby button or the red button on the remote control once). If I react quickly enough and press on the remote control, e.g. menu - the projector is still working. If not, it turns off the lamp and goes to cooling (the diode is blinking orange). The strangest thing is that the projector itself can start accidentally at random intervals as it has power (it is in standby mode). I do not understand what's going on. I desoldered tact switch power from the motherboard thinking that it caused such anomalies but unfortunately it didn't work. Please Help my.
