The Power Supply module can be simply removed with the following process.
1. Turn the lamp off
Switch off the WN-5220-V using the remote and allow
the cooling cycle to complete (3 – 4 minutes) before
switching off the AC power at the rear-panel switch
2. Remove power cord
Remove the AC power cord from the WN-5220-V
3. Remove the Screen (front
access) or Power Supply
Access Cover (rear
access)
4. Loosen the 2 thumb
screws
These are captive screws and should not be totally
removed from the Power Supply. Just unscrew them
from the chassis.
5. Disconnect the DC power
cable
Lift the Power Supply module out far enough to
disconnect the DC power cable.
6. Remove the Power
Supply module lid
Set the module on the front edge of the VideoWall’s
chassis. Remove the two side screws attaching the lid to
the module.
7. Disconnect the high
voltage lamp cable
Pull the spade connector off of the high voltage lamp
supply. Remove the nut and washer securing the other
high voltage cable. After removing the high voltage
cable from the Power Supply module, replace the washer
and nut on the threaded post and put the lid and it’s
screws back on the defective module.
Replacement is the reverse of the above procedure. When repositioning the new
module, make sure that the power supply mates with the two locking posts on the
side of the module. It may be necessary to force the Power Supply module towards
the chassis side wall to accomplish this.
