Question about JVC LT-40X776 40 in. LCD HDTV
Turn on TV. Illumination Lamp comes on but no sound nor picture. We cannot turn off the set. After approximately 1 minute the Illumination lamp starts blinking. Set has worked well for 9 months. A few times in the past the same symptons occured but we could unplug then plug the set back in and that would remedy the problem. Tried it many times to day with no success. Also have tried pressing the control and volume buttons simultaneously as recommended in the book. Have switched cables coming from the Dish and Switched control boxes (DirectTV)
If the set is only 9 months old, you should call for warranty service right away as this coiuld be a costly problem. This problem sounds like the main board is bad and you will be looking to pay about 500 to 600 bucks if you do not get it repaired under the warranty. Good Luck

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
