Question about Optoma EP738 Multimedia Projector

2 Answers

Ep738 not creating any image just a white grid.

As I turn on the projector and the white Optoma logo normally pops up on a black background. Instead what happens is it goes to a white grid and no matter what I do it just shows the white grid. I tried cleaning out all the dust but that didn?t help at all.

HI i had the same problem with my Optoma showing the white grid when turned on, and it is not a problem of the lamp not being good good. Sounds odd, but i removed the lamp. then dropped the projector against a hard surface from say 10 inches from floor, tehen a hard tap on the side, then inserted the lamp back in, turned on the darn thing, and it showed the Optoma logo alright, with 2 vertical stripes, then i removed the lamp again, repeated procedure, and by this time the lines wer gone and i got the projector to work again, including all push buttons on panel (this wasn´t possible when i had that problem. It really worked for me. At least you can try it.

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.

Have optoma ep738mx projector is set for ceiling mount want to change to desk mount

Need to check on the menu to see if the provision is possible , open menu and scroll to see if the screen can be inverted. If not you will need to get help from Optoma dealer , Check on the rear for any trip switch to change the settings as I do not have the manual for reference.

The RED (of RGB) is not firing

Its a problem in either your cable or the projector board. Get a new cord, if the red still dosent work either purchase a new board (expensive) or buy a new projector (slightly more expensive, but worth the investment with the board going out probably more parts to follow). You decide wats best for you.

Color problems

i don't know if this will work but..... I have an Optoma h27 and we were having problems with the color and ours is mounted on the ceiling in inverted also; and after two years we started having color problems, come to find out that on the menu there is a option for high altitude and that had been turned to the "off" position (probably by our kids resetting all the options and not turning this one back on)..... after taking it to a tech that cleaned it for $97.00 and said there was no problems he could find, we played around with the remote/menu and came across this high altitude option and when we saw it was on the "off" position, we put it to the "on" position and another fan inside the projector came on and that helps to keep the inside of the projector cool at all time and helps from the color becoming weird..... Try this on yours and hopefully that will solve your problem.

No power

check power source(electricity)-power cable-door cover of lamp is closed firmly-if you reset button press it-check power fuse.

Vertical white line

My EP719 had the same problem. Did it once, briefly, soon after I bought it, then not again until recently, when the line came back more frequently and wider.

 

The projector was 20 days past warranty, and the company would not honor. So much for customer satisfaction and loyalty. Last piece of Optoma equipment I will ever buy!

 

Anyway, I found a web item on another model of Optoma projector with the same problem. The solution this guy tried was -- I kid you not -- rapping on the thing. With nothing to lose, I tried this on mine. Tapped lightly on the top and noticed a change in the width of the line. Hmmm ... it was sensitive to this.

 

Tapped harder. The line got narrower. Rapped pretty hard -- thump! -- and the line disappeared.

 

Since then I have been running the projector for hours, turning it on and off, letting it cool down, starting it up again. And the line seems to be gone. It may come back, of course, so this gonzo fix may not be permament. But if it works while I'm using it at a presentation, think of the amusement it will cause!
