HDMI interface issues

You may have a fault in the HDMI cable. Swap it out first.

Unplug unit, wait 10 mins then plug back in. If still does not work, check for breaker trip. Be sure outlet still has power.

There are three only three possibility's here, one there is a problem with the HDMI HOOK UP ON THE BACK OF THE TV, SECONDLY IT COULD BE THE DVD PLAYER IS NOT COMPATIBLE WITH THAT TV, AND LASTLY YOU MIGHT NEED TO HAVE THE TV SERVICED FOR SYSTEM ISSUES

Where is the rear bulb??

usually you need to plug the HDMI connection back in, and power everything up. Then using the menu, set the HDMI connection, back, to whatever you wish, often it is efficacious, to have the alternate unit already plugged into the set. It may also pay to reset your TV set, back to defaults.

Try hooking something else up like a playstation or dvd see if it works so you know if its the box or the tv

This is not an HDTV. However, that does not mean you cannot use it to view the HD channels with DirecTV, you just wont be able to view them in hi-def. Use the component inputs from the directv tuner and plug those into the proper component inputs of your JVC. Once you see the DirecTV picture on the screen, go into menu... setup (with the directTV remote) and make sure that the only resolution checked is 480i. DirecTV with 'downconvert' those cannels to standard def, and they will still look pretty good though the component connection...

... now, in answer to your next question: "What exactly do I need to view HDTV with DirecTV?"...

1. A television that will accept 720p or 1080i signals.
2. A DirecTV HD Tuner.
3. Any DirecTV service BUT you must purchase the HD pack so that they will 'unlock' the HD channels
4. The proper cables to hook in between your DirecTV HD receiver and your HD-capable TV/Monitor. You may use either HDMI or component video cables, so long as your TV will accept them. Tune your TV input accordingly. When using component video cables, you must also run a separate cable(s) for audio...

Take care,
Rob

ps. DirecTV HD tuners do not have an RF 'out'. ("coaxial or ch3/4 connection")

You have a faulty power supply in the receiver.It has to be repaired,it seems to be a common problem

same problem on two different h20 receivers - called directv and explained the situation each time. since these are leased receivers, new ones on the way.
