generally when you get a constant green light all is ok. these different lights indicate different problems within the tv. so the pattern of lights you mention suggests there is a fault of some kind (is there a troubleshooting section in your manual)? either way it needs to be looked at.

Can't get t v on

1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

Probably power module bad.

Begin with the headset turned off. Press and hold down the silver call control button in for 6-10 seconds. The light will flash blue first. Continue to hold the button down then release the button when the indicator light starts flashing red then blue.
