I believe the LC420WX7 would be a suitable equivalent for the LC420WU5 - depending on your circuit layout, they should work the same way as the originals did when new. In many cases, these "upgrade" components are interchangeable between brands and models.
Philips always updated component part numbers for their TV products over the years; ICs, EEPROMs, flyback transformers, tuner modules, etc.
I'd say the later type number parts would work - give them a shot.

Not always but usually the inverter board is part of the display panel, way to much money to bother fixin.
SOURCE: part number for the samsung le52m87bd backlight inverter
Hey!
I also have a SAMSUNG LE52M87 LCD TV and I have the same
ANOYING BUZZ comming from ( I think ) backlight converter. - I am
almost 100% that its because of the backlight inverter while the sound shifts frequency when backlight is changed ( from 1 - 10 ), but the volume of the buzz stays the same. Only the tone changes. I have this TV for a year now and havent realy noticed until now, so I think it started buzzing recently, because I didnt hear it before ( and I got realy sensitive hearing :) ) ...
ITS DRIVING ME CRAZY ...
PLEASE post what happened when ( if ) you changed the inverter,
or what did you do to solve the problem ...
Many thanks in advance!
