Power Supply Removal
Place the television on a flat surface face down with a blanket or other soft,
clean fabric to protect the screen. If there is a stand attached to the
television, allow it to hang off the flat surfance for easy removal. (A bed
works great for this). Remove all screws on the back of the television and
carefully lift off the back cover. If your television has a stand, it should
slide out. The power supply can be located by following the wires from the AC
plug. It is usually close to the middle of the television. Carefully remove any
connectors from the power supply and unscrew screws holding it to the
television.

Capacitor Removal
Locate the capactior requiring repacement. Flip the power supply board over and
find the solder points holding and connecting the capacitor to the board. With a
hot soldering iron and the power supply on it’s side, heat the solder point
while carefully wiggling the capacitor with your other hand until you feel it
seperate. Repeat for the other solder point. If you are having trouble removing
the capacitor, try using the desoldering wick outlined in the next step.

Preperation
Still working on the bottom of the board, place the desoldering wick on the
solder point where the capacitor was removed. Push down on the wick with the
soldering iron to remove solder from the hole which will allow you to insert a
new capacitor. Repeat for other solder point. The solder will literally be
sucked into the wick.

Installation
Install the new capactor in place from the top of the board. The negative white
stripe on the capacitor should line up with the white half circle printed on the
power supply board. Push the capacitor legs into their holes and from the bottom
of the board, bend the leads away from eachother to keep the capacitor in place.
Working from the bottom of the power supply board, hold the tip of the soldering
iron at the base of the capacitor leg at your solder point and push the end of
the your solder string into the tip to fill the solder point and secure the
capacitor in place. Repeat for other solder point. Be careful not to get solder
on other portions of the power supply board as this could cause a short circuit.

Repeat for remaining capacitors. When complete, reinstall power supply in
television and ensure you have reinstalled all screws and plugged in all
connectors.
