Have replaced the power board more than once. when I replace the board, it becomes fully functional for about a week and then the power issues start coming back. symptoms include: wont power on at all. power cycling every time you use the tv helps sometimes but its inconsistent. sometimes it will work, other times it wont. there must be something else other than the power board causing this issue.
Hello Travis, the power plate delivers two or three voltages needed to start the device, on the Main board, there are also other sources that are used to feed this same board and that can fail, that's why you have changed the plate source and over time it continues repeating the fault
I'm sending you a link, about someone who has a replacement plate kit for this model
I am also sending you the user manual, where you have the technical assistance number
I hope you find my comments and data useful, also that you can solve the TV problem in a definitive way
Greetings Franco Dosil
Hola Travis, la placa de alimentaci?n entrega dos o tres tensiones necesarias para el arranque del aparato, en la placa Principal, tambi?n hay otras fuentes que se usan para alimentar esta misma placa y que pueden fallar, es por eso que has cambiado la placa de fuente y con el tiempo continua repitiendo la falla
Te estoy enviando un link, sobre alguien que tiene un Kit de placas de recambio para este modelo
Tambi?n te estoy enviando el manual de usuario, donde tenes el numero de asistencia t?cnica
Espero te resulten ?til mis comentarios y datos, tambi?n que puedas resolver el problema del televisor en forma definitiva
Saludos Franco Dosil

SOURCE: Which Replacement Power Board for LNT4665F Samsung LCD TV?
Howdy,
It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.
Thaks for using FIXYA, BIG IRISH.
SOURCE: My Vizio VX32L LCD TV will power on but no picture or sound
I had the same problem after having a Vizio for 2 and a half years. I
left the room for a minute, i came back and the screen went black.
There was still power to the unit and you could see that the back light
was working, just no picture, no sound, and you couldn't use any of the
buttons. The only way to turn it off was to unplug it. It would then
start up, with the Vizio logo going from orange to white, and then do
the same thing all over, no pic or sound.
HOW I FIXED MINE: I ordered a new "main PCB" from tigerdirectparts.com
(you can also use searspartsdirect.com). This is the circuit board with
all of the inputs on it (hdmi, cable, etc.) I opened it up,
disconnected the old one, put in a new one and now it works fine. I used
both serial numbers on the board to search for it online. It cost me
$144 to do it, but that's better than $450 for a new TV. My tv is the
vx32l hdtv10a. I hope that helps.
For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

What I'm learning is there are several models of Panasonic TV's that have a video card that doesn't play well with HDMI applications and the end result is, you need to call this number and not only make arrangements to replace the bad board,but also this!
Your model doesn't show below,but I'd certinly inquire about the necessity of a "Firmware" update!,,,Panasonic knows FULL WELL they have a HUGE problem here!
Hope this helps!
At panasonic.ca I found the listing for the fw update under customer support-important notices
