The power supply board is the BN41-00296B also known as NB24BS/NB21BS.To do the repair you will need the following tools: Soldering iron, de-solder braid, Phillips screwdriver, flat blade screwdriver.

If you don’t want to do the repair yourself, then please use the service request link above.
The first thing you need to do is remove the monitor stand, power cord and signal cord.
Now use the flat blade screwdriver and insert it on the bottom of the unit between the two halves of the case and the latches should start releasing. Once they start just work your way around and set the back panel to the side.
The next thing to do is remove the metal RF shielding from the power supply and CPU boards. You will need to remove a bunch of Phillips screws as shown below circled in yellow.
Now you will see the boards that we will be working with. The power supply board is the center one and the inverter board is the one on the left hand side.
The two boards we will be working on will need to be removed from the unit. The capacitors that need to be replaced are circled in yellow on each board below. The power supply board uses the (6) 1000uf 25v caps and the inverter uses the (4) 220uf 25v caps. Remember, be sure to insert the replacement capacitors with the polarity correct. After the capacitors are replaced then reassemble the unit and you should have a working monitor again.
