I have been servicing my Panasonic PT-L757EA today, the 3 lcd displays were marked by humidity and needed to be cleaned. So I removed the motherboard and covers then done the cleaning of every optical component as I was there, then cautiously put everything back together. After refitting the top console, I turn on the power supply and nothing happened, no power at all. Usually the fan goes on straight away. I have serviced a.few.other projectors in the past and the whole operation went fine everytime..No idea of what is happening now. let me know if you have any idea of what can have gone wrong.
Thanks in advance.
