Almost all sets have a brightness and contrast (which is often labeled picture instead) in the main customer menu-----look to see if it changes the picture or not.If issue is the picture is there but somewhat slow to appear or dim the model indicated uses a lamp which may be the real problem...

Some of these had problems where the micro for the Dlp gets confused, they have a jig to connect the set to a computer and download two updates on sd cards---it may or may not cure this but this is a shop repair.

Hi,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
Good luck in solving the problem...

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.
