Re: Cheaper ESR meter
I built it based on this site: [url]http://www.qsl.net/iz7ath/web/02_brew/15_lab/06_esr/index.htm[/url] and I am using a DMM to measure the current. It always shows maximum current flow. Some issue I find many others share with building based on this design. I wonder what it must be, and what rectifies the issue.

Re: ANATEK Blue ESR Meter REV 1 PCB first build. Tips and component upgrade suggestio
I wonder if it is possible to integrate a lot many functions into one hand held device, since there are already small enough individual testing devices such as those as [URL="https://www.badcaps.net/forum/showpost.php?p=156825&postcount=20"]Peak[/URL].Re: ANATEK Blue ESR Meter REV 1 PCB first build.

Re: ESR meter - recommendations?
It would be so very good if there are some DIY versions for these meters.
Was [URL="http://kripton2035.free.fr/analog%20esr/esr-lowohm-silic.html"]this[/URL] version(Silicon Chip ESR & low resistance Meter, published February 2005) tried? I believe that guys with DMMs could make use of it.

Re: SMPS shows output voltages within range, yet doesn't boot the system.
Well, that [I]is[/I] the case.
I'm going to now replace the PSU itself following your suggestion of giving up attempts at this one. However, I would want to know why it leaves no other options. Is it the economics, or is it that any further investigation would be too tedious/complicated/uncertain?

Re: SMPS shows output voltages within range, yet doesn't boot the system.
Update:
I have been rechecking the voltages on the PSU, and I now find that the 12v rail shows 11.07v to 11.13v. The time I first checked and posted this thread, it showed 11.46v to 11.48v.
I seem to have 'found the cause' why the PSU did not boot up - the 12v rail. The 5v standby and POWER_OK show unchanging values, at 5.04v. The 3.3 volt rail shows 3.36v and the 5v rail shows 5.24
I am beginning to wonder if this can be corrected properly, so that it performs like...Leave a comment:

Re: SMPS shows output voltages within range, yet doesn't boot the system.
Pictures from my camera Intel CS630 did not show anything clearly enough, so I dropped the idea of taking pics and posting.
It is a DEER PCB with DR-200ATX v2.02 printed on it. It was sold as the brand Zebronics here in India. Some browning of the board is there at one of the resistors R66. The caps I removed are of a brand called Viva, and the ones I put in as replacements are Teapo.
I've used it on a Pentium3 System with only the D815EEA Board, Processor, RAM and the HDD.

As the title says, the PSU doesn't boot the system. It only does after CMOS is cleared each time. I tried with a different PSU it worked okay.
The PSU had apparent leakage from the base of a pair of caps. I replaced them with new ones, yet the same issue persists. It shows voltages on the 12 volts at 11.5 v etc. All of the voltages are alright as per the link below.

What might be the cause I wonder.
As to the 'leakage', there are no physical issues with the caps, like... -

CRT gives a 'film projector sound', does not stay power-on.
Hello all,
I have a Samsung Samtron 55v 15" CRT colour monitor in use with computers since 2001 till a month ago, which gives a regular sound as if some scrip of paper is flapping against spokes of a wheel, or like in the title, a 'film projector sound' is an approximation. Think of the sound as at 3/10 volume.
At first when the monitor showed problem, display/tube would 'extinguish' as soon as it was switched on, like it would when switching off a CRT Television, but kind of 'implode'.
As I began to attempt to find the cause of the problem, the...
