Sony VPL-CX4 projector locked up

I have been using the subject projector for 5+ years with absolutely no problems.

Today I was giving a presentation and we broke for lunch. I went to turn the unit off by pressing the power key twice as always. The unit would not turn off and all of the keys were not having any effect on their repsective operation.

I finally ended up unplugging the unit, plugging it back in and turning it on. This time the bulb would not light but the coolng fan started up. I was also not able to turn the unit off again.

I again unplugged the unit and plugged it in again. This time, the unit would not power up at all and the fan/temp & lamp/cover led's began blinking. They've never come on until today.

Do you guys have any idea as to what's going on with this projector?

Keypad buttons probably need a good service.
you say you pushed power key twice
did you leave a small pause between each push
get a tech to checkout underneath keypad buttons to make sure that the contacts are clean.

Our remote went missing so I'm trying to use the other remote that came with the projector. This remote is model number RM-PJ2. Should I be able to click and move forward with the slides on Power...

Make sure the USB cable is run from the projector to the computer. You might also want to open device manager (right click my computer>properties>hardware>device manager) and make sure the projector does not have a yellow triangle with an ! on it. You can also try unhooking the USB cord, deleting the projector from device manager, then hooking the USB cord in again to reinstall the drivers. It should all be stock drivers, so you shouldn't need to download anything extra. Also be sure that the batteries in the remote are good and working. Sometimes you can point an infrared remote at a digital camera and see the light on it (I've never gotten it to work though) to verify that it's working.

Blue Haze on screen Sony cineza vpl-hs50 projector

Its your blue polarizer going bad. This happens over time due to the excessive heat generated in the projector. The main problem is that your projector has organic LCD panels that degrade over time and in turn degrades your blue polarizer. The same thing happened to my sanyo Z2. It took 5 years for it to show on my Sanyo because I only use the projector for sports and movies. not daily tv watching. In any case, it isnt worth it to spend the money ti fix it...jut put tat towrds a new projector. The latest crop of LCD projectors almost all use in-organic LCD panels that last much longer. Hope this helps.

Sony VPL-DS100 will not turn on

I had same problem. The cause was a blown fuse (T5.0 Amp 250V). You have to open the case and then get below the print that is under the alloy cover. it is quite simple to fix. A fuse costs 60 cents.

Sony LCD projector light turns purple

I had the same problem on my 3M projector, i found that the problem lay with the cable.

My case was solved by turning the cable around i.e the end which was in the computer is now connected to the projector.

Try the above or try a new cable.
I hope this works
