    Yamaha RX-V375 AV Receiver with a No Power Problem

    Good work so far, good luck with the repair. Because you have an output transistor failure, look for those (internal) speaker output fuses while you're inside your unit to make sure they didn't also take a hit.

    Yamaha RX-V375 AV Receiver with a No Power Problem

    The REASON your unit is shutting-down is that it has internal protection circuitry and/or devices that are intended to protect the sensitive circuitry within. The more often you try to bypass this protective circuitry to do troubleshooting, the greater the chance that you do more damage to the...

    my remington electric shaver (plug in) fell, broke open and the leads disconnected-

    This is the problem. You can see what these connections go to, but we're just guessing. After disassembly, the unit is so compact that you're probably going to have a hard time fitting everything back together so that it functions properly. This is what you should have: One side of the incoming...

    I am trying to repair a Tektronix 2712 Spectrum Analyzer that stopped all of its menu & display

    I don't remember, but others here have recommended a Tektronix web-site that has a lot of experienced guys who know specifically about Tektronix gear. Maybe somebody else here will supply you with that website in a following post. My recommendation for now, considering the description of the...

    Forklift LiFePO4

    I don't know the laws in your country, but in mine a forklift is serious business because of legal liability issues. If you do something incorrectly and the forklift fails while in use, or a fire results, that's a serious legal problem. If you do this yourself, then plug it in overnight to...

    my remington electric shaver (plug in) fell, broke open and the leads disconnected-

    I can't see the electrical connections in your pictures well enough to make guesses. Do you know anybody that does electronic-type hobby repairwork? If somebody with more experience takes a look at this up-close, they should be able to identify if it can be repaired or not.

    Electrical safety blow

    Alright, I think you mean that you turned the fan off at a switch. And now it won't turn back on (?) First check any fuses or circuit breakers (your electrical power supply to your building), that may have tripped (interrupted the power to the fan switch). If that doesn't fix the problem, make...

    Electrical safety blow

    You know what you're talking about but we don't. It's not the language, it's that we don't know what the aeration equipment is that you're talking about. Is this a commercial unit made by a manufacturer that we can look-up on the internet? With what little we know, I would think you need to...

    Yamaha RX-V375 AV Receiver with a No Power Problem

    Did you Google your make and model number and see if you can find a schematic on it?

    Need help IDing board

    1) What is the company name and model number of what you got it out of? 2)Are there any company names, logos, or other identifying information on the board?

    Brig 001 amp: Left audio channel allways strangely quits working after some minutes

    Two possibilities come to mind for me: 1) The switch controlling the speaker selection needs to be cleaned or replaced. That's the most consistent problem I've found with the symptom you describe (especially the 'hit' that brought the speaker back into service temporarily). You may be able to...

    Parameter in determination of electrostatic discharge

    I'm a little confused about exactly what it is you're trying to do. Are you trying to 'measure electrostatic discharge' on a regular plastic bag? Or are you trying to do that using an electrostatic discharge bag made for that purpose? Bag specs should be readily available from the manufacturer...

    Fixing a lamp

    It was specially made for that item, you won't find an exact replacement (unless maybe the manufacturer would have one they'll sell you). I don't know your skill level (or exactly what that switching device is supposed to do, because it does have an on/off switch outside of it). I'd try to...

    Who knows what kind of connector

    I'd use a magnifying glass and check the connector over closely to see if it has a company logo or identifying number stamped on it. If not, it'll be almost impossible to know who actually made it. If all else fails, you might try to contact the board manufacturer (the company that made your...

    No sound from radio speaker, but can hear from headphone jack

    I don't know the electronic part stores in your area. They're probably available on-line, but I'd just check your local phone book and find an electronic parts store, computer parts store, or similar entity. The reason I suspect the jack itself first is your symptom and the fact that you bought...

    Help - ceramic disc capacitor

    They're marked 'L1' & 'L2' Typically 'L' designates an inductor (ie: a wire-wound impedance for AC, as opposed to a resistor in a circuit). Since they're just wire, wound around a tube, it's really hard to destroy them. The wire however is lacquered, so that the windings don't touch each...

    Another one Tek 2235 power supply problem

    You shouldn't have a problem finding the manual online for this scope. I also own a 2235. Tektronix doesn't make parts, they buy them from component manufacturers and install them in their equipment. Tek usually just tells those component manufacturers to put Tek numbers on them. (I wouldn't...

    Another one Tek 2235 power supply problem

    You should find the schematic and/or maintenance manual on-line for this scope. Maybe the Techtronix web-site will have one for free. Tek usually mark their parts with their own numbering system, different from JEDEC. There are cross references here in the 'Resources' section, and on-line to...

    Help - ceramic disc capacitor

    The MOV is a semiconductor designed to absorb voltage spikes, which can be very quick. A fuse element has to heat-up to open, which apparently wasn't as fast-acting as the MOV. As I said, I'd be checking the components in that circuit to make sure something else didn't fail before I just...
