Re: Dell W1700 LCD Rev00

he is true I have found the 4 broken transistors with the 2 fused and the 2 condensers 220/25volt broken
the 4 transistors in Italy I don't succeed in finding them, that model is? 4600?
help me
thanks

@Bob
ciao sono Italiano
sul mio dell si sono rotti 2 caps+2 fuse e 1 Q80
Però sostituirò Q80+Q81+Q40+Q41 per essere piu tranquillo
ditemi dove posso trovare il data sheet dei Transistor 4600?
grazie

THERE IS A SIMILAR
thanks

Re: Dell W1700 LCD Rev00

may be it is is a 2SC4600, but without a picture or the missing other markings no one can answer your question.

And' an IC to 8 pins

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.



@ 4600
BD313K

Re: Dell W1700 LCD Rev00

P/N should be BD313K. Try just BD3xx search.

Re: Dell W1700 LCD Rev00

dear friends
I thank you I immensely now see the datasheet and I will make you know
thanks

Re: Dell W1700 LCD Rev00

you excuse but I think it is not him the BD 313k it is a CASE TO3
WHAT I LOOK FOR IS A DUAL LINE 8 PIN
THANKS

Re: Dell W1700 LCD Rev00

I know what you are looking for. It is probably a dual mosfet from a unknown producer.
I have seen similar an BD4661 in a Scaleo View C19-4.

I was not able to find a datasheet, but may be the following ones may fit:

http://pdf1.alldatasheet.co.kr/datas...F/IRF7389.html


But only guesswork from my part, w/o data sheet it is always a gamble.

Re: Dell W1700 LCD Rev00

perhaps this is what I look for
I thank you

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!

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......

thanks

Re: Dell W1700 LCD Rev00

@ Gonzo
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

Re: Dell W1700 LCD Rev00

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

Success

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.
