Hi guys,I bought a JVC RS1x projector this summer and I realy love it...but since 3 weeks when I watch some movie the intensity of the image change every 15 minutes (like the lamp change her power normal to high),this problems appears with my Oppo Digital 983 ,my Xbox 360,my PS3 etc...and I heard a little sound ( like a kind of Whistling) that I d ont hear Previously...

Am I in trouble ......please give some help thanks

p.s. sorry for my english I am a french Canadian

This happens sometimes; try running it on high power until it stabilizes.

could be bulb prob, run on high power as suggested, also do u have a spare bulb in hand. You could try switching out bulb. But def run on hi-power as I had the same prob around the 700hr mark.

Ive tried ti run on high power mode ,the intensity change again but she pass to every 15 minutes to every 45-60 minutes .I put it back to normal and the intensity still changing every 15 minutes.....is this normal ,should i use it only on high power mode (i don t like it ,it s too clear and i loose some black)......

What else can I do...I read it s maby a power supply problem....Can you guys give me other informations please...

Sorry, that's all I know.

You can ask JVC.

Could be a bad bulb that needs replacing.
