www.VanceBaldwin.com is about the least expensive option I know of if you're not a dealer... You might also consider PTS Electronics or Tri State Module if they have the jig for that one, having it rebuilt. You can also look at ShopJimmy.com they carry a wide range of use boards and guarantee them to be functional.
BTW: If you need the service manual email me privately and include enough info that I know what we're talking about... I get almost 3000 emails a day so I'll be lucky to remember this post tomorrow. :)
Getting old too!

I had exactly the same problem. I finally found the power button on the underside of the TV. It is well hidden and to find it, you need to run your fingers underneath the panel. Turn it off for a minute or so and turn it back on and then turn on the switch on the panel on the upper right side where the channel and volume buttons are. It works.

Is sound cutting out? What problem are you having? Set could need new Software Version. Need to Live Chat!
