SOURCE: I have a JVC-HD projection TV model 56G786 and all

Hi,

The JVC 56G786 users manual will not give you a clear or specific answer about confirming bulb failure with the LED lamp or power indicators located on the front of the TV.

If the TV was operating normally for an extended period of time (months or years) and will not start, the problem is almost always bulb failure. If the "Lamp Replacement" warning previously appeared "On-Screen" and the TV will not start, bulb has failed.

The first step in a "no picture" situation with a JVC LCD Rear Projection TV is bulb replacement. There is no way to measure the bulb. Sometimes the bulb is visibly broken or damaged when it fails. Remove the lamp cage and have a look.

The JVC Lamp Gallery has all the JVC models and lamp numbers listed. There is also a link to DIY JVC bulb and lamp installation.

If a good bulb is installed correctly and the TV still does not start, you need a technician. There are no user serviceable parts other than the bulb. Failure of ballasts, power supply boards or controller boards is rare in these TVs.

SOURCE: My JVC HD-56G786 will not work with HDMI cable.

Check your TV's video resolution setting if it matches those from the source device (same 720p or 1080i) and see if that works.
