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.

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 want to pair my laptop (lenovo N100) to my mobile (samsung corby tv) i could not find the pin ? please give me the steps


Does your laptop have a VGA-output port? an S-Video port? a HDMI output port? component-output port?

Does your TV have a VGA-input port? an S-Video port? a HDMI input-port? component-input ports?

Match the "output" to the "input", and you should be OK.

HOW DO I CONNECT A AN EZPRO 610 PROJECTOR TO A LAPTOP COMPUTER.


1. You will need a VGA or S-video cable and a 1/4 inch stereo plug that will go from the earphone jack to the EZpro then out to a amplified system for the sound.
2. I believe the EZpro has connections for HDMI which will supply sound as well as High definition video. You should have an adapter for the HDMI also if you

I cannot get the Input 3 HDMI port to work. The Input 3 Componet videoworks, but when I unplug the componet video and put in HDMI port nothing works. I do have something else in the HDMI Input 1 port...


Hi.

To start ensure that each time you connect or disconnect the HDMI ports both TV and connected device are off.

Also ensure that HDMI input is active, as detailed here.

HDMI connectors carry voltage, and connecting the HDMI cable while TV or device is on may easily damage the HDMI port, making it unusable.

The HDMI 3 and Component 3 are separate input. The component input may work, and HDMI port may still be defective.

To test the port do the following:

Disconnect TV power cord, and connected device (eg. Receiver, DVD etc.).
Leave units disconnected for five minutes.

While power is disconnected, test connecting on port three a device that was previously working on HDMI 1. Also use a cable that you know is working.

Connect back power with HDMI cable already connected. If HDMI 3 is still not detected, then the port is defective.

In that case ring Pioneer at the number listed on the owners manual.This model is often advertised as only two HDMI inputs. Call Pioneer to ensure the third port can be enabled.

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.
