Question about Panasonic PT-47WX49 47" Rear Projection Television
Those boards are no longer available through panasonic. The only option is to have yours rebuilt. The link I provided for the resistors do rebuild boards you may want to leave them a email with your model number and mention its the A board. I am not sure of what the cost would be , But I do know that board was 485.00 when panasonic had them still available, as quite a few of my customers needed that signal board for that same chassis.
Heres that link again

Here are some basic steps that will help you fixing the problem.
I'm assuming that your unit is dead set without an standby LED
light and your outlet is live.1.Power cord - check the cord it might be opened (no
continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse-
sometimes the fuse fail because of the power
surge, replacing with new one will cure the problem, If this is the case I
would advice you to use surge protector/AVR (Automatic Voltage Regulator).
However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the
linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and
still the unit didn't power up then you have an open parts on the power supply.
4.If you see that the fuse is intact , don't attempt to touch anything
because there some fatalcomponents
stored electricity enough to hurt you with a simple mistake only. I would
advice you to look for a
professional to troubleshoot
the power supply. If you want to repair it yourself make sure that you have
necessary tools and test
instrument. First check bad solder joints(re-solder all
cold solder), leaky
electrolytic capacitor(sometimes it has bulged at the top but not all, you better
have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat
sink), open fusible resistor (caused by shorted regulator
Transistor/IC), shorted zener
You may also replace the entire power supply board, click this LINK.
Hope I helped you.

If you don't have necessary tools
and test instruments, and can't do the job yourself, I would advice you to
look for a professional to troubleshoot the problem. Don't
attempt to work internal if you don't know the safety precaution of handling it, there some stored
electricity enough to hurt you with a little mistake only.
Hope I helped you. Have a nice day! Thanks for using Fixya.
