Question about Sony SuperLite ultracompact Project VPL-CX5 Multimedia Projector
When I first plug in the mains cable, there is no back light around the on/off button on the top of the projector, and of-course, it wont fire up, either manually from the button or the remote control.
I can wait up to 20 minutes for the light to come on; when it does, bingo, we are away; no probelms at all.
I have changed the mains cable, fiddled with the lamp cover; nothing makes any difference; it still will not come on when first powered from the mains.
If the light for the power botton is no lightig the problem is from the power suply to the switch looks like there is a line contact or probably fuse the one it has false contact check for soldering open or components loose if the termal protector was the problem just the light will not work but the fan and the power botton it have to be on let me explain this electricity from the outlet 120 a ac goes thru the cable thru the transformer that will reduce and convert the ac to dc when the current pass trhu the diode transformer reduce the de 120 to 12 and the diodes convert from ac to dc after that goes thru the fuse from the fuse the conection goes thru the switch from the switch to the termal protection device and to the fan and to the lamp and with a paralel conection will conect the rest of the board

Of course this problem is some where in trigger circuit.
some kind of FET has got damaged inside for sure.
that is what is the problem.
you last comment is very correct i think.
if power is turning ON after 20min also it means it can turn ON.
but matter here is its turning ON late.
this must be a reason from some trigger circuit.
this can be better solved by having a service manual in hand.
in this case i shall recommend you two things.:
1:first of all get a service manual
2: if you dont want all this head ache go for a tech who shall replace the trigger circuit for you.

When you turn it on, do you hear the Fan whirring at all?
This could be due to a burnt out component near the power supply, if that goes, well, the whole thing goes.
Check for anything that smells or looks burnt.
Please let us know of any questions or more information so we can help you better.
