    Araldite Rapid, Cyanoacrylate & PCB material.. does it stick?

    I'd be dragging a cut off wheel chucked in a Dremel tool . . . . . and dragging it from side to side , instead of the linear in line motion that you would normally use, that then really roughs up the surface and leaves no gloss, therefore, a better adhesion performance.

    LG OS 5020

    Sir PMS . . . . a . . .POSSIBILITY . . . . I wouldn't be surprised if some HV diodes or caps in the HV multiplier stage have failed . If you have your DC supply voltage to terminal 1 of your T601 transformer present, then move to the CRT Bias supply which is being derived from transformer...

    What is this? Driving me nuts

    Is it "faulty" because its being "shorted" . . . . . as it looks like a ferrite / powdered iron cored inductor of ~ 4 turns of #18 enameled magnet wire, being wound at one end of it, then being black shrink wrapped. Then some nice illegible white symbolization of . . . . PA4-1027-? . . . .is...

    Perpetual moving sticks

    Sir FrenchConnection67 . . . . . Looks like absolutely everything that I had surmised about the stand alone power board for the main boards power, turns out to be true. If this was a customer return item, and was being resold, as is , its probable fault was the unit stalling out to a dead stop...

    Panasonic PV-M1323-A 13 VHOLD issue

    URGENT CAUTION . . . . neither of those . . . FOCUS + SCREEN . . . are even REMOTELY related to the cause of your fault, and their maladjustment can seriously impair picture quality. No touchee - touchee. As for that shown problem it appears to be a compatibility problem. That TV combo is...

    Technics RS-TR515 - power issue? (Novice)

    Basically, after a period of play, the tape stops and if I look at the display, it flickers a bit before settling HOMEWORK . . . . On that unit is the play button still pressed down or is this electronic instead of mechanical activation , and those actions are being solenoid activated . The next...

    Tv remote codes

    Sir carlosboyd . . . . . I've used the searching technique for the code in AV1 or AV2 mode without success. And I don't think that you will . . . . even in another 1000 years. You will have to use the LEARN mode. BTW what piece of equipment is this AV-1 and AV-2 function on ? It sounds weird...

    Cannot find this specific resistor, help!

    It will be easier to find a 2 W metal film, than a wire wound in that wattage category . . . . quite hardy ! . . . . as I have seen them working in the dark . . .as a dull glow. It's easy to find a 3 or especially a 5 W wirewound unit but that will DEFEAT the fusible effect, provided by this...

    Cannot find this specific resistor, help!

    If that's with it having at least one of its leads out of circuit, when ohms testing, then you are in the market for a replacement 1 ohm 2 w resistor.

    Freq Generator

    what the hell is this device (supplied in pics) that Im starting to see in AM/FM Radios FAR BETTER . . . . that you could have given an applicable model number of radio so that its circuitry could have then been analyzed. INSTEAD . . . i'm going to have to say that you have run into the 1st...

    Cannot find this specific resistor, help!

    If reading 24 . . . .WOW ! . . . 24 VOLTS! . . . . across that RESISTOR, suggests that it is being an open circuit. Confirm same, using your meters low ohms function.

    Mig welder wire speed controller problem

    This time around, have the meter clipped into circuit and be getting a reading.Have the cap installed with the negative lead connected, but with the + lead disconnected and free. Then move the cap positive lead to connect, but for just an instant. If no fuse blowing fallacy again, then...
