    I have a Panasonic PT-53X54 rear projection lcd tv. Yesterday when I
    turned it on, something very weird happened: the image appeared to be
    ballooned and too big for the tv!

    My guess is that somehow the lens that the bulb shines light through
    got knocked out of position, and is sitting too close (or too far?)
    from the bulb. Does anyone have any ideas on how I can repair this?

    It'd take quite a hit for the lens to be knocked loose. I'd be more
    inclined to suspect an electronic issue, does the set have a zoom function?
  3. Besides, you wouldn't end up with anything close to being focused with
    a random lens reposition.

    The high voltage might also be low.

    Well, I did move it in the back of a uhaul... that might have
    something to do with
    it. It's been working for ~6 months w/o problems though.
    I did manage to fix it after I figured out how to get into the service
    (thnx avsforum!). I just had to tweak a whole bunch of parameters.
    On the
    upside, my convergence has never been better!
