Smd diode code

[gipiv]

Hi,
looking for some help,
does anyone know the value of these smd's D604, D6655, both faulty ? Are they zener diodes? I've included pictures of them
They're mounted on the power supply board of a Dell 2408WFP.
I was wondering also if anyone knows the values of the smd capacitors (which are unmarked)
C709
C710
C629
C630
C610
C609
C613
C614
C627
C620
C626
C624
C623
C621
C628
(many thanks bicycle6228 for the schematics).
Many many thanks for any help as I don't have a ton of experience.

Re: Smd diode code

they arent zeners, so probably a 1N4148 will work.

Re: Smd diode code

D604 and D655 are shunted by low value resistors. Are you measuring these diodes in-circuit?

Re: Smd diode code

As stj indicated, they are LL4148 diodes. These type diodes and ceramic caps almost never fail on these power supplies.

Hi
thanks to all for the replies. Very very appreciated !
Yes I am measuring them still in-circuit (mea culpa !). I was going to remove them to test again and make sure they are okay.
Does anyone know of a good reference for the codes of the smd capacitors I could check out to decipher the codes and perhaps complete the schematic.

Thnaks again !
