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:

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

I know how to use a web brower.
Step two: learn how to have it go to a search site like google.

Did many a Google search on the web and in the newsgroups before
posting here.
Step three: learn how to enter usefull search terms like
"sci.electronics.repair faq"

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.
step five: look for stuff on repairing tv sets like:

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.
