Question about Optoma EP719 XGA DLP PROJECTOR 2000L 2500:1 CONT DVI-D WITH HDCP Multimedia Projector

2 Answers

Optoma EP719 lamp does not come on

Projector is in standby mode (green light blinking). Push power on the unit or on the remote, the green light stops blinking and stays on for about 3 seconds then goes back to standby blinking. No fan noise, no lamp light, no other noise of any kind. Also, none of the other led's light. Lamp looks to be good. Any help is appreciated. Thanks.

    Sent in the same description to Optoma tech support. They mentioned it could be the ballast or lamp driver. I took the unit apart yesterday and found a bulging capacitor on the power board. Will replace and see if that helps.

    Solution!



    That was it! Bad 10v, 3200uF capacitor on the power board. Replaced it and the projector is alive and well again!

Ok, so forgive me, I'm going by memory. Take the top cover off (4 screws on the side). Take the top silver shield off, look at the screws and only take off the ones you need. It's ok if you take more off, but its just more screws to track. You will need to take off the back outer cover. You will need to unscrew the hexagonal screws that the vga-out port uses to screw the connector to, as these are holding the back plate on. Once you get in, the board you need to look at is on the bottom back. Look for a capacitor that has a rounded top, not flat like the others. You will need to replace this with the same voltage and capacitance. Try an electronics site on the internet to get the right replacement if you cannot find it locally. Sorry for the poor instructions, but its just been too long. As a practice, take pictures as you go (during removal of parts) and you can use them to reinstall. Hope this helps as mine is still working.

I have the same problem. The 10V 3200uf capacitor is bulged. Can't find one on the web. Where did you get yours?

HOW DO I un-lock the scanner on a Brother MFC 7420?


Unfortunately, the MFC-7420 doesn't have a physical lock switch. You need to turn off the all-in-one and wait for the unit to clear its memory. If the error recurs after you press the power button again, wait 30 minutes and try again. (Note: you will lose any faxes that are in memory. See the User Guide page 11-5 to save this information.) You can find the manual on the Brother support page for the MFC-7420: https://www.brother-usa.com/support/ModelInfo.aspx?R3ModelID=MFC7420 . Click on the Manuals & Documents tab. Then click on the Manuals on our Online Solution Center for the English version of the manual. The direct link to the User Guide is currently: http://download.brother.com/welcome/doc000387/ALLFB_UsaEngUsr_B.pdf .

You can also try unplugging the all-in-one for several minutes to reset the error codes. If the error persists, contact Brother if the MFC-7420 is still under warranty (1 year). If it isn't under warranty, consider replacing the unit. The repair costs may be unreasonable.

I hope this helps.

How does the bulb look? Is it bright or kind of dim. The bulb warming error is designed to halt use of the machine until the scanner bulb reaches the correct output level. As these are basically a flourescent tube, they will dim over time and at a certain point they will not generate enough light to enable proper scanning. If the bulb is dim, it will require replacement.

HP printer psc 2210 all in one


Chances are that you didn't lock down the scanner when you moved the unit. You can attempt to open the unit and move the scanner bar manually to reset it. HPs are very difficult beasts when it comes to their power up check out. It must be fully functional...including all cartridges...to work in most cases. Good luck.
