Windas does seem work also without signal generator (like ASTRO SG)... It return an error during the work, but it work properly to write eeprom (I don't had already used, I had only read this).
I' m sure that in Windas there is GDW-FW900 in three version. Moreover, in this LOOOOOOONG thread:

I had read that some people with the W900 monitor had solved its problem with Windas. If, of course, I had understand it correctly... It's a very long post, but it is very interesting...

Well..some people says that this feature is probably searched by Sony, due to compense the aging of the tube. But sometimes the compensation (I think that, with the age, the tube lost a part of his normal brightness) is too high, and so the monitor appear "overbright". For this reason, I think, the Sony Service don't solve the problem if you gave to his service labs the monitor: they said that "The crt is ended, and it need a new tube"... If you read the long thread of the link, you can find persons that fix it forcing the brightness to the valour of 130, 150, 110...some different valour. Every says that "the monitor is now perfect", but I think that is quite strange that the same monitor is "perfect" with some, different, value of the brightness. Probably, they find the better solution due to the age of their monitor (and also, of their tube)..according to the Sony's theory about "increasing brightness due to life" (..if there is this theory...) Also my 21" one was under Sony service, but they said that -the prevoius owner- must spent over 400 Euros to solve the problem, replacing the tube... Of course, he don't choose the reparation, and gave to me the monitor "as a gift for experiments". Probably, I think, if I fix the problem with Windas, after 12-18 months I'll have a monitor that is really "ended"... Obviously I want to fix it...but I'm not very very sure about a future, long life of the tube...
Of course, IMVHO: I'm still waiting rs-ttl converter, and so I don't know nothing, at this time, about my monitor. I'm sure that Sony declare, for my monitor, a G2 tension of 512V, and I've found 599 volts.....a little bit high... (please consider that I'm italian,so please excuse my poor english)

The FW900 is a newer monitor with a flat screen. The W900 has a curved screen and I assume it has a different chassis. I mentioned it because I recently saw one for sale that looked good except for a blue background with retrace lines. Andy Cuffe

You'll have to fix it by adjustment then. 2000 is too early for this feature.
Does anyone know why these monitors get brighter as they age? It seems like a strange way for a CRT to age. I've also noticed that these monitors get dimmer as they warm up. They are way over bright just after initial warm up and settle down to normal brightness over the first 10-20 min. Andy Cuffe

..uhmm..I don't know...but you can try to solve the problem using the resistor solutions.. You must find the service manual, and find the voltage partitor in the RGB AMP board...and try this solution. think that, if you have the BIG fortune of living in America, you can find a lot of store that probably can sell to you,for a very low price, a FW900 with the same problem, but that you can fix (of course, probably...)using WINDAS. In Italy is impossible to find those screen....also find a 21" for about 100 Euros (of course, with the brightness problem..) is a VERY BIG fortune...
