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

Open Question

EP719 DVI port stopped working

DVI stopped working today after the display told me to use YpBpr because DVI was compromised. I can get it to come on for a few seconds but then the display just turns off. Tried factory reset with Power, left, left, menu, still no luck. Calling optoma was useless as it isn't supported.

    I have replaxed this cap a few times (I have many in stock) but only due to the fact that the display won't come on at all. I don't think it is the cap this time due to the fact that I can use rca to get a picture; as well, I do get a pic for a few seconds with DVI before it cuts out. If your pro opinion is still the cap then I will do it, I can do it in about 20 min now! lol

There is a stuffed 10v 3300uf capacitor on the power board. You need to replace it.
Bellow you can check in the picture where the capacitor is located.

Notice that in this picture I have already took the bad capacitor out and replaced with two small cords to reach the bottom and test the new capacitor.
To reach this place is not fast, several layers of plastic and metal must be removed, but is not a hard task to take the capacitor out and replace it for another.
It works just great! Now it is back on track with awesome image.

In order to reset the bulb counter you need to access the Service Menu:
To access the Service Menu:
Turn on and warm up
press the following sequence:
Up
Up

Give it a few goes, it took me 5 minutes to enter with the right timing. The Service Menu will appear, highlight factory reset and the counter goes to 0. Job done. Cheers, Matt.

Link ASUS laptop to Sharp Aquos LCD TV


No, a DVI to VGA adapter will not work. (The TV is looking for the digital signal from a set top box. This is different from the analog signal on the VGA cable.) You need a converter. Your best bet would be a VGA to component video converter. (I am assuming that the Sharp TV has a component video input.) This page has some examples: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215.html?sorter=productname-en-asc . Note a VGA to component video cable will not work. The VGA to component cables are for projectors that read the RGB signal. The component video signal is YPbPr.

Connect the VGA cable to the converter and the component video cable to the TV and the converter with the computer and TV off. Turn on the TV first and set it to the component video input and then turn on the computer. Then (assuming the VGA port is enabled - adjust in the BIOS if needed) set the computer's video output to the VGA port. (On my Windows 7 laptop, this can be done by right-clicking on the desktop. Choose Graphics Properties and set the display to the external monitor or both. Click Apply and then confirm the change (on the external monitor if using the single monitor). (VGA to Composite video converters also exist if you do not have an available component video input on your TV.)

If your computer is fairly new, you may have an HDMI port. Your TV may be able to read the signal with a DVI to HDMI cable. (It depends on the TV. Not all of them will read the computer's signal on the DVI port. Check the documentation for your model. TVs without a VGA port are less likely to support this feature.)

I hope this helps.

My HP L2335 Monitor wont display anything. I can literally turn it on (the led power light comes on and it turns green if plugged in and I can tell the backlight is on), but nothing will display no...


why not try a dead display on 2 machines 2 PCs
using only 1 data cable at a time why try to confuse it????????

the OSD must work, or the display is bad or the power supply to it is dead.
easy as apple pie.

the monitor has a tiny computer inside it (micro)
on mine, the data lines dead shows NO SIGNAL in the screen
every time you I power up my monitor with data cables pulled off.

best is to read the book for your monitor, and run all the tests it

I have an Optima Model EP719 Projector. Suddenly I am getting white vertical lines and can't find a solution for removing them.


I would try switching out the DVI cable first. It could be faulty. This would be the easiest and cheapest solution to check.

Nvidia GeForce 7200 GS PCIE - Multi-Display does not work


This card does not allow you to Multi-Display with the VGA port and the S-video port. If you put a DVI to VGA port adaptor (not supplied) on the DVI port, you can Mulit-Display two VGA monitors and (presumably) a VGA (from the DVI port) and S-video monitor.

This is not explained anywhere and the card does not come with a DVI to VGA port adaptor, so I wa only able to work this out after I bought the DVI to VGA port adaptor.
