SOURCE: I have a Sony VPL

Flashing of Temp/Fan led light is an indication of either the unit gone to excessive heat or Fan failure.
To isolate it from overheating, make sure that the vent is free from dirt(dust build-up) to have sufficient airflow.
I've suspected that you're unit has a faulty fan inside. If I'm not mistaken it has 3 fans, two fan can be easily identified while the other one is inside the unit. It is a sorroco fan like the picture below.

First thing to check is the connectors of the fan. Pull-out it and then re-insert and ensure that they are properly seat in. If the symptoms still persist, you have to identify which fan is not working upon powering on the unit and then replaced it with new one.
Hood block assembly(top cover) is secured by screws which is covered by blind rubbers.
To guide you on how to disassemble the unit, click this LINK to download the copy of the service manual. This manual also contained the error code that you've encountered right now.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Projector vpl cx21 cust the edges of the image

In the menus there should be an "image" adjustment option, it could also be related to the "sync" rate. Try different settings. You may also need to adjust the resolution you're sending to the projector from your computer.

Sony VPL-CS5 menu will not display

Give input signal to the projector and see that if the menu appears or not on the screen.
if menu comes on the screen then put the backgroung color to blue, instaed of black.

if nothing comes on the screen, then the LCD panels are faulty.
