    Vizio TVs are the armpit of the industry (Polaroid, Element, Memorex,
    etc are from a point even lower). For Vizio plasma TVs, most of the
    stuff that fails is part of the plasma panel - sustains, buffers, etc
    and can be found by looking for the vendors part number. If you find
    numbers that start with LJ, it's a Samsung panel; LG Electronics
    starts their part numbers with 6871. The power supply may be supplied
    by Samsung or LG Electronics, or it may be from a third party. The
    same applies to the main board, although it is more likely that it is
    a Vizio product.

    Visio LCD TVs are more of a problem - they often are a mismash of
    parts - one vendor supplying the power supply, someone else supplying
    the LCD panel, the inverter from a third party, and Visio supplying
    the main board.

    Possible sources include eBay (but you must be very careful about
    feedback and description) and places like Discount TV Parts, Shop
    Jimmy, etc. Googling the board number should bring up a number of
    sources.

    One important detail - most sellers indicate their boards are from TVs
    with damaged screens, and are good. Some even offer a warranty.
    Given the number of different TVs, and the time it would take to test
    the boards, that is reasonable. But be very cautious about those who
    state nothing more than 'Untested'.

    One additional resource - www.badcaps.net/forum has a 'Troubleshooting
    TV and Video Sources' section. Some of the people there are pretty
    good at troubleshooting common problems.

    There's still a lot of money fixing and/or buying and re-selling test
    equipment. I gave up on all consumer electronics over a decade ago.
     
  4. Google turned up several sources, all in the US.
    I'm viewing this e-mail on a ViewSonic CRT monitor, which was recommended by
    a friend, and turned out to be better than any Sony I'd owned. (It uses a
    Mitsubishi Trinitron.) Vizio was founded by the same man who founded
    ViewSonic.

    I was surprised at the "unkind" remarks about Vizio. I bought a 32" Vizio
    for my den several years ago, and it is startlingly good. (For example, the
    horizontal viewing angle is 179 degrees.) My living room display is a 60"
    KURO, and the Vizio /does not/ provoke a "yuck" reaction in comparison. With
    good program material (especially NBC), the Vizio is a knockout. This sort
    of quality does not happen by accident.

    Perhaps you haven't explored the process of manufacturing a plasma or
    LCD tv. Vizio, Philips, Panasonic, Sony all follow the same general
    process. They buy an LCD panel from one of the limited numbers of
    companies which manufacture them (Samsung, LG Electronics, Sharp are
    major suppliers). That panel includes the tcon and backlight system
    (CCFLs and inverter, or LEDs and LED driver). The TV manufacturer
    then adds a power supply, main board (which includes video processing
    and control components, tuners and inputs), speakers, etc. and puts it
    in a case. Thus the difference between a Vizio LCD TV built around a
    Samsung panel and a Sony built around the identical panel is the main
    board, the case, and other incidental parts. Even the major parts of
    the main board come from a very limited number of suppliers.

    When receiving a digital broadcase the signal is received as digital,
    is processed, and sent to the tcon where the digital information is
    directed to the appropriate pixels at the proper time. Other than the
    component and composite inputs everything is digital. There is no
    difference in the way the signal is processed.

    I would expect that TVs built with identical panels would produce
    identical quality pictures when adjusted to the user's preferences.
    So where does the difference between Vizio and LG Electronics lie?

    1. The components on the power supply and main board, in particular
    the capacitors. Vizio is notorious for using cheap Chinese caps in
    their power supply. Capxon Elite, and Lelon are popular brands.
    Capxon is popularly known as Crapxon, the other brands are even worse.
    A bad filter cap in the power supply will not affect the picture until
    it deteriorates to the point the main board will not function.

    2. The warranty, warranty service, and especially out of warranty
    service. Vizio does not want to see your TV ones it leaves their
    factory. They will grudginly replace a TV that fails within the
    warranty period. The usual replacement is a 'refurbished' model;
    under some circumstnces they have required the owner to return the
    failed TV at the owners expense. Once it is out of warranty, they do
    not want to have anything to do with it. All you can do is take it to
    an independent shop and hope they can repair it without schematics.

  6. and MAG too.

    I sort of liked their older monitors before they got cheap and shitty
    looking with strange curves.

    The Taiwanese were pretty good at making decent computer monitors.

    I bought a mainboard for a 32" Vizio from Sears:

    These guys also had the same part:
    http://vizparts.com/index.php

    The remanufactured board with shipping was around $130 from Sears. Vizparts
    was more and they also have a restocking fee of 15% and charge a 'core' fee
    which you can get back if you return the bad board. Sear doesn't have those
    restrictions. The hardest part of my repair was removing and replacing the
    zillion screws. TV is working like a champ now.
