    Re: ESR readings

    That's still not sensitive enough. You'd have to divide the last portion of the scale (0 to .2) into 20 marks (.01 ohms each) to see a problem.

    Don't waste another $35. Save your money and get AnaTek's Blue meter.

        Still not fine enough resolution for troubleshooting mobo caps? I see range of 1.0, 0.5, 0.2 and 0.

            Darn...

            Read feedback:

            "Unit was made in and shipped from China not from Verdun, QC, Canada as stated."

            I'd say pass on this deal.

                Re: ESR readings

                Well, I bought my ESR meter on Ebay, from a seller in Poland. It is housed in a brown bakelite case, is powered by a 9-volt battery, and is obviously homemade.

                This cost me $60 CAD. I looked at the Blue meter, but it would have cost me about $150
                assembled and I didn't know if I would be interested enough in recapping to make it worthwhile.

                Long story short, I have become a recapping enthusiast, done about 10 motherboards and many soundcards.

                The Polish meter is accurate enough to spot bad caps, but any good cap wil go to a zero reading within a second or so. It detected some bad OST 6.3v 1500uf caps, reading was .20. When I read the caps off-board, the reading was 1 (maximum).

                When used on bare capacitors off-board, it will give readings on new caps very close to the published specs.

                Is the blue meter way more accurate?

                If I were doing this for a living as opposed to a pasttime, I would opt for a better meter.

                    Re: ESR readings

                    is your meter simillar to the one used in this clip
                    http://www.youtube.com/watch?v=VRoBt...layer_embedded
                    ? (go to 2'38'' into video)

                    such meter obviosuly has one decimal point less of a precision than either esr blue, or this
                    http://translate.google.com/translat...tm&sl=ru&tl=en
                    which is much cheaper than esr blue and it measures capacitance (costs about 70$)

                    esr micro was discussed in this thread

                        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                        by Tynan Dill
                        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                        Upon bringing it home and plugging it up, it showed a standby light.

                        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                        The screen seems to blackout and stay black, but with a flashlight I can see the display.

                        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                        Assuming...

                        Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
                        by tvguy12012012120
                        This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

                        Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

                        Yet another Samsung QLED Boot Loop
                        by Takeatry
                        Samsung QLED QN50Q — purchased 2022 started experiencing a delay in the picture coming on in the morning less than 2 years later. Did not know the term boot loop at that time. As the loop delay ran into a few minutes did all the recommended troubleshooting, soft and hard reset, changing cables and outlet locations, no help. As the delay increased contacted Samsung tech group and allow them remote access the tv. Tech was moving too fast to see exactly what he was doing but this ultimately it was also no help. Lived with the delay until it stretched out over 6 hours. Pulled of off the back cover...

                        Modification of a Fluke multi meter that uses three AA batteries to use a 14500 lithium ion battery
                        by sam_sam_sam
                        I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board

                        I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery...

                        Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
                        by flibidy
                        I have here a Magnum IA.100 which belongs to my parents.



                        The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


                        Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.
