1. If you haven't done so already... Unlplug the TV!
Remove the rear lower outside panel using a phillips screw driver. Set
the panel aside somewhere where it won't get tripped over and broken.
Remove the screws from the lower metal panel that hides the electronics
and connections. When removing this panel from the back of the TV,
there will be an exhaust fan attached. You will need to disconnect the
fan's connector in order to set it aside to get it out of the way. Take
note that all the connectors inside the TV except for one on mine had
the ends labeled with a code so that they could be matched up when it
comes time to plug things back in. Just make sure that when you're
disconnecting the connectors that you number them or code them if they
aren't already marked as there are probably 10+ connectors that will
need to be undone in order to get the electrical chassis out.
4. Remove the big metal plate on the left side of the electronics chassis. This will help you get the electronics chassis out of the TV
5. Slide the TVs power cable
up and out of the slot that holds it in place. This will also give you
slack to move the electronics chassis out of the TV so you can work on
6. Unplug the USB and Firewire connectors from the top of the electronics chassis.
Carefully slide the electronics chassis away from the TV. Take note
that you will have to start to disconnecting connections now in order to
get the chassis out of the TV, I didn't fully remove mine from the TV.
There were just too many connections that needed to be undone. So what
I did was undo enough of them so that I could set it on a chair, but still connected to the TV
Now the electronics chassis is out so we can work on it. Remove the
protective metal housing from the electronics chassis and expose the
9. Now you should be able to see your circuit
boards. There are typically two boards that have bad capacitors on
them. One is called the DM board and the other the Power board. The DM
is the hard one to get to as its the middle board of three. When
accessing this board, be extremely careful of the ribbon cables at the
bottom and sides of the boards. They can easily be broken, torn, etc...
Again, take note of the connections you have to remove and make sure
they're labeled. Take a picture of things if you need too.
10. Now that you can see the capacitors on the DM Board, look for a grouping of capacitors:
11. Now look at the Power board. Its the board on the back of the electronics chassis
. There are two capacitors to look for here: Photo of Power Board Capacitors
Are these bulging or leaking? If so, they'll need to be replaced.
Look for others while you're here. I ordered mine from mouser using
this part#: Mouser Power Board Capacitors Link
12. Once you have the capacitors replaced. Button everything back up and hope for the best.
