Optiquest Q9 Board "ILPI-025"

[mockingbird]

I've had this for some time and I took out all of the caps when I didn't know better and now I want to know which caps and series come with this board.

ILPI-025
REV: E
2007.01.15

Anyone who is repairing this can you help me out?

Looks like no one is playing with one of those.

First hit at time I looked:

Doesn't list all the caps but it has some.

Re: Optiquest Q9 Board "ILPI-025"

I just opened up an Acer with this board (ILPI-025 RevB). Mine has 4 big caps, in an arc. Starting with the one closest to the AC inlet, mine are 470uf, 25v (C502); 470uf, 25v (C817); 1000uf, 25v (C815); 1000uf, 25v (C818). There are also 3 small caps (6mm), which are: 47uf 25v (C820)(C827)(C807).

Hope this helps.

(not sure what's wrong with my board - caps "look" good. Did you find anything interesting on yours?)

Thanks

What is wrong? Does the power LED come on? With a computer connected, can you see the display if you shine a flashlight on it?

Re: Optiquest Q9 Board "ILPI-025"

Can you list me also the brands and series for each cap:

C501
C817
C815
C818
C820
C827
C807
C702
C713
C701
C707
C705

In total there are 13 caps on the board (Including the big primary cap).
Much obliged.

Re: Optiquest Q9 Board "ILPI-025"

Ok, here's a picture, I thought I could make it easier, since our board revisions are slightly different and the board numbering seems to be off:

1) C501
2) C817
3) C815
4) C818
5) C820
6) C827
7) C807
8) C702
9) C713
10) C701
11) C707
12) C705

Ignore the capacitors that are there. I replaced them with inedequate parts when I knew no better.

Thank you very much, I really appreciate it. Here are suitable replacements, all by Panasonic (Except for the primary), from Digikey, all in stock:

And the primary, if you're interested in replacing it too:

Highest length I went was 20mm, which is the height of the two larger heatsinks, so they should fit just fine.

On my board C701 is "Suscon SK" not "Teapo SH". I still have that one original on my board. Not to worry, they're both general purpose caps anyways, most likely interchangeable, all I had to do was either match or slightly exceed the ripple with a higher quality part.

Re: Optiquest Q9 Board "ILPI-025"

I found the caps I removed, it appears that they did indeed use the Teapos and Suscons interchangeably (And probably why yours lasted longer than this one - a testament that Teapo is in fact superior to Suscon). Just to compare to your list:

1) C501 - Su'scon 470uF 25V SG - 10mm x 17mm
2) C817 - Su'scon 470uF 25V SG - 10mm x 17mm
3) C815 - Su'scon 1000uF 25V SG - 13mm x 20mm
4) C818 - Su'scon 1000uF 10V SG - 10mm x 17mm
5) C820 - Su'scon 47uF 25V SH - 6.3mm x 11mm
6) C827 - Su'scon 47uF 25V SH - 6.3mm x 11mm
7) C807 - Su'scon 47uF 25V SH - 6.3mm x 11mm
8) C702 - Su'scon 470uF 25V SG - 10mm x 17mm
9) C713 - TEAPO 10uF 25V SH - 5mm x 11mm
10) C701 - Su'scon 220uF 16V SK - 6.3mm x 11mm
11) C707 - Su'scon 470uF 16V SK - 8mm x 11mm
12) C705 - Su'scon 470uF 16V SK - 8mm x 11mm

Re: Optiquest Q9 Board "ILPI-025"

To followup, the sizes you listed are identical to mine.

Thanks for the links. I've quoted you over in my thread for thoroughness.

Really appreciate your help.

Re: Optiquest Q9 Board "ILPI-025"

Thanks to mockingbird for the Digi-Key links! I'd been about to buy a $12 capacitor kit from this page:

http://www.ccl-la.com/blog/index.php...q19wb-monitor/

That's where I found simple instructions & videos on how to perform this repair. But I saved five bucks by ordering the seven capacitors that I needed from Digi-Key using the links that I found here. So all in all this li'l project cost me $25 for a 40W soldering iron, lead-free solder and desoldering braid from Radio Shack, plus about $7 including tax & shipping for the seven capacitors from Digi-Key. I could've bought a new ILPI-025 board on eBay for about $25, but what fun would've THAT been?
