Hello Manfred,
Good luck. The difference in the FW1 and FW is the polarity of
the contrast bias.? If you put in the FW1 in the older model it
will blow the transistor that supplies the contrast bias.? The
later motherboard has jumpers to set the bias polarity.
There is a long thread here where someone replaced the LCD in his
ESG, see:

Hello Tom, i do have exactly the same problem, no jumpers on the
motherboard and a?DMF-51043NFU-FW1, that will not work. The original MDF-50562NFU-FW has stopped to work, so I need a new LCD. Did you have a solution for the problem already?
Best regards
Manfred
