    I have a Mitsubishi VS-5006R projection television. The picture is
    quite good, but is offset to the right by approximately 3 inches.
    This would not be an issue except that it creates a blurry "echo" to
    the right of whatever image is on the TV. The echo usually shows up
    more strongly with a white or light background.

    Is there an adjustment I can make for this? The adjustment panel
    inside the set doesn't have a control labeled "position". It has the
    usual (tilt, bow, lin, skew) and others, but nothing immediately
    identifiable as horizontal position.

    Any help you can offer is appreciated.

    Thanks.
     
  2. You need to "adjust" about 120 bad capacitors into the trash can.
    Seriously, we have repaired dozens of this chassis in the last couple of
    years and every one has had a minimum of 60 bad capacitors. Until you go
    through all five major circuit boards, test every polarized electrolytic
    capacitor for ESR, inspected every one for electrolyte leakage, repaired any
    corrosion damage, and repaired numerous solder connections on heat producing
    parts, you are likely to chase your tail.

    While it wasn't what I was hoping for, I do appreciate your bluntness. Thank you.

    No problem. Don't hesitate to ask for more help if you need it. The good
    news is that most repairs on these sets amount to not much more than
    changing caps, repairing damaged traces, vertical output ICs, and regulator
    ICs. Tedious work, but not difficult. Save yourself some time and
    completely remove each board and wash it after removing the bad caps. be
    sure to scrape away all of the black corrosion from the traces and assure
    their integrity and make the needed repairs.
