Red square on the screen

When the projector is on even without any inputs going through the projector the screen is full of small red square all over. I replaced the lamp thinking that was the problem but it has not made any difference.

    I am not sure what you are saying here. so could I ask you to clarify.

    Also I actual have this unit mounted on the ceiling, upside down and have done for 4 years.

    So can you just clarify, do i pull it down and lie it flat normal way up, or upside down.

    thanks

    I have tried the laying of the screen flat and no luck. I am still getting vertical lines of red squares all over the screen.

    Is there something else I can do to try??

This sounds like the LCD screen is not reacting properly. Try this lay the screen flat for a day. and then reinstall it and power it up. This has worked for me in the past.

    You are to lay it flat so that the lcd screen faces face down. The goal here is to allow the LCD elements to realign to an original position.

When turning on the projector it shows the Optoma logo but will not boot to the home screen. Is there a way to reload the home screen software?


Depends on the model. If you saw a little fan, then there is a fan problem. There might be 3 fans. 2 square ones and one blower fan. Look for plugs with 3 wires(red/white/black or red/yellow/black). Those will lead to the fans from the mainboard. Occasionally the fan will spin but the tachometer lead will stop reporting the fan status and the projector shuts down. To being with I would clean out the projector fans and ducts thoroughly. That may clear up the issue. Otherwise there is a button press sequence to enable the service menu, but you cannot upload new firmware without special optoma software that isnt available. Another possibility is you have failing filter capacitors in the power supply. Be careful poking around under the hood. There is lethal high voltage possibly stored even when unplugged.

I have a Sharp DT400 projector. I replaced the lamp, and the unit powers on, and displays a picture during warm up but only for a few seconds. The lamp indicator and power lights go back to red and unit...


If you try to turn on the projector a fourth time without replacing the lamp, the projector will not turn on.

Press ON, INPUT, UNDO, left arrow, ENTER and right arrow on the projector in order, and then press ON.
The lamp 0000H is displayed on the lower left of the screen.

Hitachi projector cp-s318 and the pictures give off a red tint.


Hi,

Make sure the Computer Input is set to VGA, Computer, or RGB (depending on which projector model you have). Go through the menu settings of your projector.

Hope this helps

Display has red tint across entire screen. Could it be the bulb? If so, is that still available? Approximate cost?


two possible solutions----either a problem on the small circuit board that is connected to the RED picture tube OR the red screen control is turned up too high. These sets have a small square block with RED,Green, Blue screen controls(same place also has red, green, blue Focus controls) if you remove the speaker grill you will find an inspection plate made of masionite---the focus/screen block is visable behind it----get a flashlight and look carefully at the block---one row of 3 plastic shafts is Focus(don't touch those) the other 3 are Screens(you should see R, G, B marked) go to a blank video input(one with nothing attached) and turn the RED SCREEN CONTROL JUST SLIGHTLY TO THE LEFT UNTIL the red goes away.

Epson powerlite s4 projector is pink


I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the red color has gone out. The image is made up of red, green and blue images layered upon the screen. If the red panel has gone out then there is nothing filtering out the red light in the image. This causes a nice red hue to the whole screen.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

Convergence problem


We need a better description of what you mean by shadowing. However I am assuming: 1. You mean it ''bleeds'' off to the right when you have something with a hard red/blue drive. 2. When you turn the contrast and color down a bit it gets better. unfortunatly I cannot tell you how to fix convergence, but I can think of some other possibilities. In this case the red/blue emmision of the crt is dying off and going into saturation when driven hard. To fix, replace with a new picture tube/crt. In some cases you can get a little more life out of that tube (with a watchable picture) by having the screen, focus, cathode bias, and drives slightly readjusted. It will take someone with experience in doing these adjustments on a weak tube to get it looking as good as possible. Given the construction of the cathodes (guns) in that crt, only a very low level crt reactivate should be tried on it. The hard rejuv most crt testers give is highly likley to completely destroy the cathode on that crt.
