Question about Projection Televisions
SOURCE: No video with HDMI port
try 2 things, first use the rgb cables or video (yellow) cable and plug it into the tv using one of the imports..(vid 1,2,3 etc...) and see if that works. then check to see if you get a picture by not using the cable box, by pass it and connect it connect it in the uhv channel. also make sure you have it on the right input of the tv (meaning scroll through the input button on your remote to find the picture...i've done this a million times). still no picture try your dvd player input and if you have a vhs input see if that works. if it is the hdmi input...to be honest it's expensive and a pain to replace...

I the same problem and I found that the Capacitors used on the power supply portion of the circuit board were leaking and/or bulging. These parts were failing and as a result the problem worsened with time. If you are able to remove and solder new parts on to the circuit board follow the following procedures. Or get a technician to do the repairs.
1) Make note of connections at back of TV.
2) Unplug power cord and other connectors from back of TV.
3) Remove back of TV with a Phillips (+) star shaped screw driver.
4) Note the position of all connections to the main board.
5) Remove circuit board taking care not to damage any of the components.
6) Locate parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors.
7) Remove and replace parts with capacitors of equal physical size that are (1000 uf ). I would recommend a voltage rating of 25v or 32v. Note that the voltage refers to the amount of voltage the capacitor can handle. The higher the better.
8) Reinstall and reconnect the circuit board.
9) Replace back on TV and setup the unit as before and you’re done.
I replaced the parts for just under $10.00.

The HDMI is a digital signal connector, in the tv is handled and decoded separately from the analogue connectors. Because of that the tolerances on the signal characteristics are much tighter so , if the chip is damaged even in the slightest way, it can no longer process the signal. The video from the Xbox is displayed because the signal generated there is most likely at the limits of the tolerances.
This is a hardware fault, that no reset will fix: the AV processor is faulty and the only way to fix that is to replace the motherboard.
