    Connect the camcorder to your MAC or to your computer by using the USB.
    Open up the flip screen on camcorder and then have select Playback on PC even when on a Mac.

Hi there!
Typically the red light on lots of appliances (TV'S in particular) indicate power is available to the appliance, is this so on your tv?
If so the first thing you should focus on is resetting the breaker associated with that power outlet or changing outlets. If there is a reset button on the tv then push it. After you do this we can go on to the next steps- it sounds like the set is not getting any power so let make sure then get back to me. Good Luck and Thanks
Mr.Mike

I have a JVC DLA-X9-B projector which I think is the almost the same as the X7 and X3 the manual is the same.Its about 2 years old.It stopped working suddenly while I was watching a movie. Indicator lights were both on red and lamp light flashing orange. Replaced the lamp and it did not change the status,did cleaning filter bit , did lamp reset from the remote , did reboot and plugged it at a different ac outlet all that did not work . The lens cover is stuck at opened and the only thing you get when plugged in is the red light on and after 30 seconds the lamp light comes on orange .No fan came on no moving lens cover only flashing orange light.
From this conclusion was the power supply was working and software was a question mark either it was corrupt ,but the power cycle and lamp test start was normal and it checked the lamp and reported orange .So all the more it pointed to either the ballast or the power feeding the ballast.
I opened the projector up started with the screws at the bottom removed the the adjustable screw in legs. Removed the left and the right plastic cover ,then bottom cover, lamp cover, top cover plastic and then top metal plate cover, back cover until parts were all visible ,then put back the screw in legs a placed projector in an upright position. All this was in suspect that the ballast is the problem.

On the right black plastic cover is the lamp fan and air duct.
At the center is the lens assembly and motors for focus lens shift etc.
on the left are stacks of electronics that are stacked board on board of about 4 or 5 layers.

jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-11.jpgthis is the side view of the stacks of boards, to get to the ballast these have to be removed.NOTE LABLE ALL CABLES AFTER REMOVING THEM AS THERE ARE MANY OF THEM.Remove the side plate

jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-18.jpg
Remove hdmi and land board,carefully there are connectors on bottom and all sides of this board.

jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-51.jpgthen the next board bellow ,carefull this one has 2 side connectors on pictures top side
jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-66.jpgthis will be what it looks like.Note the bottom most is the power supply.,This feeds the ballast as well as other low voltage Dc components.THE CONNECTOR WITH THE WHITE END AND BLACK AND RED CABELS IS THE BALLAST FEED(picture above) .The ballast is located in a black plastic box above the power supply.The only way to remove it is to continue dismantling further. jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-83.jpgthis is the top view and the yellow tags you are seeing is cable labelson the wires.

jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-102.jpgthis picture is with all boards removed to check for physical burn outs on components
mainly on power supply ballast feed and ballast itself.
jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-123.jpgall boards out
jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-146.jpgthis is the power supply board it has both low and high voltage output .Low for logic boards high output for ballast.Ballast feed from power supply should put out about 380 volts dc during projector boot up and zero during orange blinking light,(you can skip this removal of power supply if you read the 380 volts output on multimeter at boot up.Do this before taking all the boards apart but remove the side plate to access the output and check the output at boot up ,warning do not short this while reading output.
jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-171.jpgpower board made by sumida and so is the ballast
jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-198.jpgfinally the ballast is out this is what it looks like,do you see the dark grey wires they lead to the optocouplers (little led light sensing switch looks like a square little box all 3 are side by side)
jvc-dla-x3-bu-will-not-power-2-lights-zogl1yh0b34d0jvl0ocjipaz-3-227.jpg this resistor came out of the ballast ,notice physical damage like a hole in the center of it,tested it out of the board and yes its dead replaced this.
.Did all the checking one by one of the components then found one of the optocouplers had gone dead.The one located in the center of the 3 replaced that ,put it all back and got it working again.
The ballast cost 300 usd I bought one too and kept it handy just incase.
But for the meanwhile the old one is back and working just fine.

Try this link: http://www.videohelp.com/dvdhacks/jvc-xv-n322s/5424#30023
1. When "REGION CODE ERROR" shows on screen after you've input your wrong-region DVD you push "ON SCREEN".

2. When the DVD-menu is showing push "ON SCREEN" again and another DVD-menu will appear.

3. Move the arrow over to the clock and press enter. The menu asks for "TIME" and you write 0:00:00 and push enter.

4. You will now see the menu for the movie. Remove the DVD-menu by pushing "ON SCREEN" once. You can now watch the movie.

were you able to play copied dvd's on this unit ? if yes then check setting on the dvd menu for things like DVD REGION and DVD playback speed and types of DVD playable, this is quite likely as i ha this problem on a pioneer model previously.

do those copied dvds no longer play on the same unit ? and you have tried them again on another unit or dvd player ?

rather i suspect problems with the DVD burn itself and its compatibility with the dvd player you are palying them on now (asuming settings in DVD enu are correct as loosely outlined above in point 1)

it may be that if this is a new dvd player than the one you played them on before, the dvd's may have to be closed in a certain way using your burning software so that they are playable on standard dvd players.
please also check that region is not an issue and that the recording speed of the dvd (the rip speed) is not too high or too low for your unit, as this data is stored on the written dvd and is responsible for the quality of the palyback data.

Unplug the JVC from the power outlet for 10 seconds. Plug the JVC TV back into the power outlet. Hold down both the "Menu" and "Volume Down (-)" buttons for another 10 seconds. Just before releasing these buttons, press and hold the "Power" button.
