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.

Probally the Ballast board have problems,if the safety switch problems,u should not have a picture at all in the first place.Now,the tv turn on?U hearing alot of clicking?Yes,the Ballast board is dead,it not igniting the projection lamp anymore.

Ur tv turn on now,hear alot of clicking?The tv LED light "lamp" on front panel flashes or light up?The tv projection lamp is dead.The Ballast board dead too,if hear alot of clicking?The ballast board help to ignite the projection lamp.

Ballast board is what turns Lamp on and CK your Fans if Lamp Fan is defective TV willnot come on.

Either a bad lamp or bad reciver board.If audio amp ic on reciver board shorts ,it will kill part of supply and lamp ballast will not turn on and fire lamp.

This is the shutdown code for the lamp ballast. I would have a technician verify ballast is bad and replace. This can be a tricky repair for a novice because installation of the ballast requires that you remove the light engine. Hope this helps.
