post a good close up pic of the board.
maybe i can id the mfr of your mosfets.
not sure if ther are mosfets......
the manu facture has a symbol like this @ only the a is a capital A.
there are a few more #'s too
the stamp on the chip is listed below. there are no markings under the chip.
also the company that sales the replacement has a better rev. so i would bet that they know the part # that works.
how about donating the old board for the betterment of the cause?

Well if put that way. I will donate it as long as I don't get stiffed with shipping charges and it will be donated as is. No complaints. Like I said before, I might have messed up one of the connectors when disassembling the unit and did not want to take a chance. Here typing on my NEW W1700 thanks a million I got it as junk and forked up the $80 at lcdparts.com.

Thanks to all!
you stated that your board had buldging caps. this is different that the board i had, the caps on my boaed were not buldging at all. so the caps and fuses replacement should be all this board needs. if no one wants it , i will get it from you. the connector shouldn't be much of an issue. could you post a pic of it?
also , i am glad that we all are working together on this......

I have replaced the fused ones and the two condensers 220/25v
I have turned on the monitor and the light of the power supply it quickly flashes because he/she sees a short-circuit
in fact I have put an ohmmeter in parallel to the condensers and I read short-circuit
I detach the 2 4600 (Q41 and Q80) and the short one there is not anymore.
I deduce that it will need to also replace Q41 And Q80 however I don't succeed in finding them.
I have decided to purchase the whole inverter on the site "LCD REPAIR LLC" to the price of 49,99$+16,50 $to send him/it in Italy and I will be surer
Thanks to all of You

the first symptom of the defect of the Dell W1700 has been a red thin line to the center of the screen.
after few months you/he/she is turned into a line black of 4mm. then to a following lighting you/he/she is quickly extinguished and all black has become.
is you/he/she also happened to You?
thanks
I am happy to report that the replacement board T501045.00MSS from Moniserv fixed my monitor. I had replaced the caps and fuses but the fuses blew again. Moniserv told me they have a 30 return policy so if it did not fix my problem I could return it. So with the no risk (other than shipping costs) potential solution, I bought the board. It arrived very quickly and I now have my working monitor back. Thanks to all who helped.
