Question about JVC LT-40X776 40 in. LCD HDTV

1 Answer

Power but no pic or sound

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

Mitsubishi WD-62526 turns on-n-off


I would bet the illumination lamp has reached the end of it's life (~$40 online). Should be easy to replace. Also possible the ventilation vents need cleaning, which could cause the lamp to overheat and turn off.

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

TV will not turn on. I press power and it sounds like it's coming on and then clicks and the stand by light flashes 7 times. Have already tried unplugging and then plugging back in after a minute


When I called a tv repair company the rep said this usually indicates that the "lamp" for this model needs to be replaced. Since he TV is so heavy he suggested that I access the trap door in back of the console and detach the "lamp" myself and bring the lamp to his shop for replacement. Approximate cost for the lamp is $200.00. Wish me luck.

No picture and sound


it sounds like the lamp is bad. a quick way to check is to put your ear close to the bak of the set by the lamp door and have someone turn on the set. if you hear an arcing sound each time the set cycle, then the lamp is bad..the number for the lamp is on a small sticker on the side of the set by the lamp door. it is easily replaced and the instructions come with the new lamp..you would be best to get an original lamp from samsung (1 800 samsung) but there are replacements on the web
