Re: Dell E172fpb
If it helps?
in my Benq FP731 (conector CN701) I read this voltages.
stanby running
TP 20--------0'07 V 0'07 V
TP 19--------0'00 V 3'30 V
TP 21--------0'00 GND 0'00
TP 22--------0'00 GND 0'00
TP 23--------4'97 V 4'87 V
TP 24--------3'30 V 3'30 V
TP 25--------0'07 V 0'07 V
TP 26--------0'00 V 0'00 V...Leave a comment:

Re: BenQ FP731, SMD transistor in AD board
<<GOOD NEWS>>
I've got, "not the original", an equivalent transistor, in my local shop (2 days wayting for it) ----> SSM3K01F by TOSHIBA, and now my monitor is working fine again.
Was a very difficult and delicate job! but in this moment THE PROBLEM IS SOLVED.
So many thanks, Samykenza for all your help...Leave a comment:

Re: Dell E172fpb
It might be a ribbon-cable problem. The cable might be loose, but it's not likely.Have you test with another monitor and the same VGA video card cable?
Sometimes is only a bad connection of a pin in the "flex band".Others is the video chip on AD board, press on it, but be careful!, (don't break anything in the process.)
Perhaps,you may need to replace your wiring.Leave a comment:

Re: BenQ FP731, SMD transistor in AD board
Hi, again samykenza.
Don't worry for your english, I understand perfectly!
At least what I was wayting!
It's "Q7" , I was searching and found the complete name --> (XP151A01C3MR)
n-channel power mosfet, that was my doubt (n-channel or p-channel) now I'm
sure, and I can replace it.
I'll try to find the same transistor or an equivalent, in my local shop and afterwards I'll post the result.
Very helpfull your pics! .........many many thanks.

Re: BenQ FP731, SMD transistor in AD board
Hi, samykenza
many thanks for your reply, but in your board, I don't know how is marked this transistor.
I can see the legs in my "PCB" marked ( D , G , S ) -Drain -Gate -Source, "is the same", and it's near LCD panel conector , in fact, provides power to it.
I've seen " t06 " datasheet and it's a PNP transistor (B, E, C). In my case is a
MOSFET, but...........which?

Re: BenQ FP731, SMD transistor in AD board
Hi,
here again.........
The transistor I'm talking is the same in a Dell E172FPB , but in diferent place.
I show you below:
BenQ Fp731 (48.L8301.AA0)-----> Q7
Dell E172FPB (48.L9201.A11)----> Q2 <--- I've saw it in a pic of this board, but his resolution don't allow read the number.
I hope someone help me now and tell the reference of that SMD transistor .
Thanks.Leave a comment:

BenQ FP731, SMD transistor in AD board
Hi,
SMD transistor marked (Q7) in "AD board" of my LCD BenQ FP731, is totally burned and I can't see nothing in its surface, my question is if someone can tell me the number of this transistor or an substitute.
Somewhere I've read it's the same on Dell E172FPB.
Thanks.
