Re: Acer AL2017 w/blown EA1532A

Re: Acer AL2017 w/blown EA1532A

Well, I'm about to try the DAC-19M002 power supply board in my Acer AL-2017A. Wish me luck. I will report the results.

Re: Viewsonic VG2230wm CCFL to LED conversion

Did the lamp(s) burn out in VG2230wm, or are you just doing this for fun?

Re: Acer AL2017 w/blown EA1532A

Starcap battery-cap replacement?

I'm looking to confirm the type of a capacitor, if it is indeed a capacitor.

This Starcap "battery-cap" thing looks like a button battery but is labeled with what appear to be capacitor values.

Re: Samsung UE32h4510 no picture (Dead IC on buffer)

Some of the listings for the 5562A on Ali seem to indicate that the CM501 is an equivalent replacement. I couldn't find a datasheet for the CM501, but some guy is waving one around a few minutes...

I don't know. Most of your recent test values seem okay except for the 340V.

Re: DC blocking caps + ? in sata data lines?

I installed the caps in the Lxx locations, because the pads are bigger there. Then I jumped the Cxxx locations instead of installing inductors. Finally, I installed the e-sata jack. It is a little...

Re: DC blocking caps + ? in sata data lines?

I just checked C204,206,208,210 with a microscope. They are in series with the sata data lines. They don't have one side going to ground like C213, 214, 217, 218 do on the two usb port data lines. ...

I'd echo the recommendations of the Samsung 470 series and Intel G2. Other brands/series just pile up dead in our IT dept, while those two hang on more often.

Re: Taicon HH replacement?

The bung is firm.

I got them from auction (http://www.ebay.com/itm/140526489748). I'm glad they are probably good because I also got KZH 3300uF 10v in 10mm, which is also hard to find in 10mm.

Re: Taicon HH replacement?

So, Nichicon HV comes in 10mm x 25mm for;

2200uF 10v

1800uF 16v

I wonder if 4x1800uF might be able to replace 4x2200uF. Aside from the uF, the ESR and ripple specs are a good match.
