Can you post a picture of this component and the board it is on?

I found a schematic for a VG2030m that may help if it is close to the model you have.

Re: 7c9l17-18l regulator?

I located and attached the service manual for a ViewSonic VG2030wm monitor.

The main board has a 1.8 volt LDO regulator which is labeled I102. Is that the component you are looking for? It is located on page 43 of the attached PDF file.

The schematic labels I102 as AP1117CY_1.8 and I did find voltage regulators by searching "1117CY".

Edit: The bill of materials list I102 as an AIC1117A-18PY.

thank you t30m31,
not wonder i couldnt find it !!
that 7c9l17 number its what's printed on the component.
and its totally different from ap1117cy.
is this what a lot of you guys call the 1117 series?
i am going to go over the squematic and try to find what and how was this ckt affected by the caps.

Re: 7c9l17-18l regulator?

thank you bud,good info ,i finally know what LDO means.
low drop output right? please correct me if i am wrong ,it says low dropout on the data sheets,so i ASSume they just kind of simplify it .
another dumb question:am i suppost to delete the posts of the items i fixed and if yes how do i do it?

Re: 7c9l17-18l regulator?

hey bud,
take a look at the service manual t30m31 sent me .
i think it has some more info then the one we got before,you tell me,but all info its welcome.
who knows you may have a use for it someday.
i guess viewsonic has a few different mods on the 2030 model,i dont know.

Re: 7c9l17-18l regulator?

That is the same one I have. I have service manuals for 2 VG2030WM-1, VG2030M-1.
