i have a sanyo plc-se20a projector. went to switch it on this evening and it would power up, then about 5 seconds later would power off (fans go loud for about 1 min then switches off) i have looked at various forums and the suggest problem is the heat (thermal) switch needs switching. the problem is i have no idea how to get to it, i have taken the case off to try and find the switch but no luck. but now the projector is not even powering up! the light isnt even comin on. any help would be much appreciated
