if the info you listed were not enough.. how other will answer and share thier know how..

you mentioned only on the power LED indicator light on steady RED. how about other LAMP and TEMP ? did FANs running or all silent ???

only Power steady RED mean no boot / STB condition. disconnect all cable input from Projector. take it out from wall socket for at least 10 minute then try to turn on,

hi there the light briefly lit on power but then went out and temp and lamp lights didnt illuminate at all, the projector was plugged in on mains wtih no other cables attached so cabling and external sources are not the problem as there isnt any other sources aconnected, im just a bit stumped tbh why one night it would operate as normal then the next night even after unplugging all the cables it didnt even want to power up in power cycle mode.

Re: Hitachi CPRX80 lcd projector

did you use the clip key between PC input to turn it off???

you can try my trick to cause error on it, for example open the lamp door or move the lamp from it place and close the door in place.. after that turn on it will register error.. plug it off.. put the lamp in place or close the door ( remove the error you did ) then leave it for 10 minute and plug it on.. it will reset the error and hopefully it will turn on
