Question about JVC HD-56G787 Television
When I turn the tv on, i hear the "on" dull sound and fan starts but after 10 seconds the fan stops and the tv turns off. The screen remains black!! Any help would be appreciated. Thanks!
The issue is with the main power board.
Based on the problem description given by you, it appears that the fan is not able to draw sufficient power to keep itself running.
You may open the case of the TV and check on the main power board, if any capacitors are burnt out.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
