    Got a dead JVC 35" (or maybe 36") TV.
    Model AV3589S
    I hear the relay click when power button is pressed.
    No LED's light up on the front and no high voltage
    felt on screen.
    Haven't opened it up yet to check B+ or other supply
    voltages (damn this thing is heavy).

    Any repair tips would be appreciated.

    Step one: learn how to use a web browser.
    Step two: learn how to have it go to a search site like google.
    Step three: learn how to enter usefull search terms like
    "sci.electronics.repair faq"

    step four:
    visit http://www.repairfaq.org/REPAIR/

    step five: look for stuff on repairing tv sets like:
    http://repairfaq.ece.drexel.edu/sam/tvfaq.htm

    Pay attention to the section about high voltages if you want to avoid a
    painfull mistake.

    I know how to use a web brower.
    Did many a Google search on the web and in the newsgroups before
    posting here.
    I have this repair faq.......doesn't tell me anything I don't already know.
    This may be useful.....but doesn't give me anything model specific.
    I have many years of experience working on TVs and computer monitors.
    You've told me absolutely NOTHING. Now what I have here is a dead
    JVC TV with no service manual or schematics. I'm sure I could get in it
    and familiarize myself, and eventually fix it, but in order to maybe save some
    time and troubleshooting, I thought maybe someone had encountered
    this problem before. Thanks for nothing.

    ESR the caps in the stand-by power supply and regulator circuit. Check the
    obvious things in the deflection circuits. Good Luck.

    Doing a google search, I found three references to high esr capacitors
    in the power supply taking out the regulator ic. Start there.
