    help repair router adapter

    Sir pharaon. . . . . . . That ripple doesn't sound excessive, considering a 170 + Vdc level and the their low amount of capacitance. Next test would be to see what the DC voltage measured across the C2 capacitor is and how much it changes to BEFORE you even get to that critical 1 minute...

    Testing capacitors in amp circuit

    . Sir msintros . . . . . . . How frequent is your problem occurring and has it proven to be more related to the equipment being cold or after a warm up ? I fully think that I could give you a methodical testing procedure IF I had the units schematic. "I ain't finding nuttin" . . .except a...

    configuring 3 power supplies in parallel

    Sir Procto . . . . . . . What are these guys doing that is so bad or are they doing some tricks we can't see? I consider that they are incorporating that circuitry that I have shown . . . . .as being built into their supply. It does sort of make a power supply " goof proof" on hook up, by the...

    What diode is this?

    The smaller size would not be relevant to any naming, it typically would be related to the wattage rating of the unit. In your case, you will be just fine with that little xtra wattage cushion .

    Needed Clarion DRB4375R front panel datasheet

    . Sir Cevi . . . . . . . We KNOW that one of these units will have what you need. But is this face plate a security type of thing, that you lift off and carry with you, so that no one will be wanting to steal the remaining faceless radio? Therefore, the removed "Faceplate" would be...

    help repair router adapter

    Sir pharaon. . . . . . . Is it starting to get hot in one minute or does it take 5 minutes ?. I forget if you have a DVM or an analog pointer meter. What we need to find out is the amount of AC ripple present across both of those filter capacitors. Its safest to tack on some smaller...

    What diode is this?

    Sir Dasaniman . . . . . . . See if you can afford any of these since. I see no "onesies-twosies" being offered. http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR0.TRC0.H0.X.1+ufd+ceramic+capacitors.TRS3&_nkw=.1+ufd+ceramic+capacitors&_sacat=0 PLUS that axial case...

    LG Flatron L1942T-PF monitor no power

    Sir mikey579. . . . . . . Of ALL of the photos that we have, I find it hard to find ONE that shows the components good enough to point out the connection points of all three test LEDS in one photo. Let me just describe them: For the 5V supply LED see if you can connect across the R211...

    What diode is this?

    . Sir Dasaniman . . . . . . . No diodes today . . . . . .instead . . . . . It's being a common 0.1 ufd ceramic axial leaded capacitor With a temp stability of : K5U: a maximum capacitance change of + 10% - 10% over an operating temperature range of + 10°C to + 85°C And their cases...

    configuring 3 power supplies in parallel

    Sir Procto . . . . . . . Pray tell us . . . . WHAT transmitter do you have that operates, using an INEFFICIENT 12VDC voltage level at that FIERCE of an amperage ? Both of your drawings seem the same, only with your improvement and learning curve being enhanced on the seconds better layout...

    Need the model number of this auxiliary jack.

    Sir Tiidriioblaan. . . . . . . Its a look-a-like-a-dis ? I'll bet that will be FUN-FUN-FUN, on a miniaturized . . .Flash drive on steroids . . .item like that. The only two connections I see, are a mini USB for music loading and an earphone jack . . . . . and I'm betting that either...

    JBL Home subwoofer ES150P/230 buzz noise

    Sir aimen06 . . . . . . . What I think has happened to YOUR unit is simply the mere failure of one or more of four electrolytic capacitors in the power supply circuitry of your JBL woofer amp. That would result in a loud UNCONTROLLABLE buzz . . .or HUM as I probably would classify it. Your...

    Microwave repair help

    . Sir Jared . . . . . . . I tested the magnetron from both terminals to the body of the mag. Is it semantics here or am I just making a misread ? The measurement should be from terminal to terminal of the magnetron that you say is now being void of its pushed on terminals.. Then check...

    Automotive LCD Broken :(

    Sir UncleJeffers . . . . . . . What does this display come from . . . . a top of the line Ferrari or a Volkswagen bus ? Fortunately the lighting caught the right reflection . . . of one of your photos, to confirm that it is being a 3 digit " Union Jack" display. A Union Jack configuration...
