you may need a new bulb

Your bulb is about to die. Order a new one soon and replace it now, or replace it when the other bulb burns out.
Same thing happen to me.

The same thing happened to my Sony DSC-T70 today after I dropped it. White screen with green vertical lines. Need help!

If you are getting the same problem with both TV monitors it could then be assumed it's an input problem to the TV monitor. If you are using a digital output from your receiver it could be the cabling. If you are using an analog output from your receiver it is probably coming from the receiver.
Digital video processing does have issues with darker scenes.
Can you try another video source seperate from the receiver like a DVD or better yet an analog VHS, if you still have one. Good luck and let me know.

Well this camera has no manual controls so it's merely compensating for the lack of available light by lowering the shutter speed. I don't think there's very much you can do about it -- maybe you can try to lower the EV -/+ setting (I forget what it's called, it makes your image darker or brighter). If the camera didn't lower the shutter speed you would simply get dark pictures where you can't see anything
