My first guess is to inspect the lead try the easiest solution first then approach the difficult after .
The second course is more painful if the lead is indeed ok then you are probably looking at one of three things constant plugging in and pulling out has caused microfractures on the pcb circuit isolating the HDMI plug ,Or dry joints on pcb , And failiure of input components on circuit . Sorry not to be the bearer of better tidings but this is one of those faults that make an engineer scream ?
WITH JOY £££$$$$££££ as it is going to take ages to find ?... Regards Vortash
Unless it is a common fault and is described in the engineers service notes lol.

Hooking up projector to laptop with only HDMI port


The PG-F320W has a DVI-I port between the VGA/Component input and the VGA output. You will need an HDMI to DVI cable or a HDMI to DVI adapter and either an HDMI or a DVI cable. If you use the audio input of the projector, you will also need the audio cable between the computer and the projector. (Make sure to disable the HDMI as the audio playback device. In Windows, go to the Hardware and Sound Control Panel. Then go down to Sound and Manage Audio Devices. Click on the Playback tab and check your output device. Click on Start for Windows 7 and earlier, Windows Key + X for Windows 8. Then select Control Panel.)

Monoprice.com has good prices for most cables. The HDMI to DVI cables are here: http://www.monoprice.com/Category?c_id=102&cp_id=10231 .

The manual for the PG-F320W is available here: http://www.sharp-world.com/products/data_projector/pgf320w/pdf/PGF320W_ex1_en.pdf . See page 21 for the DVI cable connection information. See page 61 for video resolutions that the projector can handle.

I hope this helps.

Hi i want to connect a tv to my optoma hd 66 projector


hi,
You can't be able to connect a tv to your projector, because it doesn't have a monitor out.
There is only one way. If the source is a DVD player then connect the its HDMI output to the projector and the component video out to the tv. You can't be able to get video out from the composite video output of your DVD player, when you are using HDMI. When plug the HDMI it will switch off the composite video out. The component video out remain ON whether you connect HDMI or not.
ok

I just got a new Optoma HD20 and only after 1day of use it is not showing HDMI signal, although it is showing VGA signal. Why is this?


Hi miracles4all: I solved HDMI signal issue in my Optoma HD20. In my case it was the lack of contact between the HDMI cable plug male ending and the Optoma HD20 HDMI female port. My 35ft cable plug male HDMI ending was not completely "seating" in the Optoma HD20 HDMI female port. I solved the problem by purchasing a HDMI female to female coupler and adding a 3ft HDMI cable that had a slim male ending. This 3ft HDMI extension cable made better contact to the Optoma HDMI port and the projector was immediately able to detect HDMI signal. Hope this helps you... kaufmanekpr

I have an optoma HD20 and it connects using a 1.5m HDMI but as soon as i try a 10m HDMI connection (even with a booster it does not connect) any suggestions welcomed?


Hi kgomer782 I have similar issue. My optoma hd20 signal connection with a 3/6ft hdmi cable is perfect. However, no signal is detected when connected to a 35ft hdmi 1.4 cable. The 35ft cable is indeed working becuase I tested it succesfully when connected to a 1080p HDTV. Did you received any solution to your problem? I wonder if it has anything to do with the HD20 design of the "debossed" hdmi ports that prevents the cable plug from getting completely "seated" in the port? My 35ft cable has a flat square male ending however, the 3/6ft cables have slim male ending that seems to accomodate perfectly in the Optoma's hdmi port design...kaufmanekpr

Optoma HD72 flashes red and green. I changed the lamp but the problem wasn't resolved. Any input would be greatly appreciated.! Greg


I had the same problem with flashing colors after playing for awhile. The following helped:
1. turn off bright mode from menu.
2. keeping the back side of the projector flat. I had it raised up about 3" on the backside before, not sure why but it worked fine when flat.
Hope these help you also.
