Re: Sony CS5 Wont turn on

The cover switch is probably not fully made.
Ensure that the cover tangs are pushing the pin
on the miniswitches.
Try putting slight pressure on the fan or lamp cover to see if the lamp/cover light
stops flashing.
you will need to do a restart on the PJ to check this out

follow this steps and fix it. God bless you

  • Secure the lamp cover and the air filter cover of the projector body if the projector does not power on. Ensure that the power cable is firmly connected to the projector and an active power plug. If the projector was turned off and then on quickly--let it sit for 90 seconds before trying to turn it on.

  • 2
    Replace the projection lamp if the projector will not power on or if the lamp indicator is flashing. Turn off the projector and let it sit for at least 30 minutes. Locate the lamp cover and remove or loosen the lamp cover with a screwdriver. Carefully remove the projection lamp from the projector housing using the handle, if available.

  • 3
    Place the new projection lamp into the projector housing and secure it to the projector. Replace the lamp cover and reset the lamp timer. Power on the projector to ensure the new lamp is working correctly.

    Remove the projector from the enclosed area to allow air circulation if it constantly overheats. Place the projector into an open area and make sure there is no blockage for the ventilation holes. Unplug the projector for at least 45 minutes to allow it to soft reset.

  • 5
    Clean the air filter to allow the projector better air circulation. Turn off the projector and unplug it from the outlet. Remove the air filter cover and use a vacuum to remove dust from the area. If the filter is unable to be cleaned correctly or is damaged, then replace it. Pull the air filter from the projector and place the new one in the now empty slot. Close and secure the air filter cover.

I have a sony vpl-cs5 but is not turn in on, some body can help me, have a blinking led that say lap/cover.???

That could indicate the following-

1. The lamp cover or filter cover aren't properly closed. Try shutting the projector down> opening both covers> closing them> restart

2. The lamp is nearing the end of its life or is faulty and you'll need to replace it.

I have changed the lamp in a Sony VPL EX-1. I have fitted a YODN (LMP - C150) I cannot get the flashing light to go out which indicates `lamp,cover` and I cannot do anything with the projector.

When you open the lamp cover for replacement of lamp there is a switch in the projector is OFF
If lamp cover not fix proper after replacement of lamp the lamp/cover indicator flashing
SOLUTION: Open the lamp cover and fix proper and tight the screw

No power after replacing bulb

The solution from bjwjb posted on Dec 30, 2009 is absolutely correct:"There is a piece on the bulb cover panel that you take off in order to change the bulb that fits down inside the bulb assembly when you put the panel back on. The bulb cover panel and the part of the panel that goes down into the bulb assembly must be present or the projector will not power up (there will be no lights either)." I would add to that once the cover is placed back, but before the screws of the bulb cover are tightened, firm pressure should be place on on the bulb cover panel on the spot placed where the plastic protrusion (a plastic "stick" about 1.5 inches long that fits into a void in the bulb assembly) goes into the bulb assembly. You should/may hear a "click", indicating that the protruding plastic piece has been fully inserted into the bulb assembly and makes contact with whatever contraption is inside the assembly to enable power-up. If no pressure is exerted the plastic protusion may not extend down far enough to make contact to enable power-up. In such case the bulb cover panel may be slightly bulging in the location of the protrusion. You would still be able to tighten the bulb cover panel screws, because the plastic is flexible. In such case you may find that the screw closest to the location of the plastic protrusion may need pushed in more. In this condition, even though you may think the cover is properly placed, the plastic protrusion is not fully inserted and does not make contact and there are no lights or power. Just take of the bulb cover panel place it back following the instructions above.

I had already disassembled my projector and was ready to bring it in for service when I did an internet search and saw the advice from bjwjb. Thanks very much!

NEC VT 595 wont turn on. Just red blinking light

I had this same problem with 2 NEC VT595 projectors. My problem was that there was a broken "tab" on the lamp cover (the plastic cover that slides in place over the lamp) that is supposed to depress a switch which insures the lamp cover is in place before operating the projector. The tab was broken in half and not making the connection there for causing the blinking status light (.5 sec on, 2.5 sec off) indicating a lamp housing or cover error.
