    I have a Sa-HE200 and it powers up but no sound from speakers after overload kicked couple times.

    Sir Dannycobb1 . . . . . With all of those years passage . . .likely the liquid portions aspect of the POWER AMPS heat sink compound has creeped and transmigrated lateraly and now is leaving the heatsink with a thermally insulative barrier of only its tin oxide element . Solved here back...

    12V 10Amps Power Supply Works for 5 Minutes Only

    Sir Nauman Muhammad . . . . .long time no see . . . . In the plane that it is is being mounted in and its positioning in respect to the windings direction, along with it not being encircled into a fully complete one turn closed loop . . . I really tend to dismiss that consideration I do...

    Sir Chipmaker. . . . . . . ( no speech impediments today) . . . . nevernosomewhathowsoever . . . .Hmmmmm . . .Chipmaker . . . . COW or Solid State ? Now yer' talkin' . . . . wish that I could had that definitive of a photo back at the get go. And on it, you can see just a minor portion of...

    Storz & Bickel Plenty Vaporizer Circuit Repair

    Thir Chipmaker . . . . (Whassamattahyou? never heard anyone wif a lisp ? ) If you refer to the first photo below , I am placing all of the markups that I seem to be able to confirm. The AC power connections and their standardized wire colors are going up to the three BLACK terminals...

    Storz & Bickel Plenty Vaporizer Circuit Repair

    Just try it and see if the unit still cuts off upon reaching set temp . . . . .you just won't have the neon as a visual indicator now. Possibly use a meter set to 250VAC and clipped into circuit where the lamp was connected.

    Storz & Bickel Plenty Vaporizer Circuit Repair

    Sir Chipmaker . . . . WOW . . .250-300 for that unit ! You seem to have your self a stubby NE-2 typish of neon lamp along with its required series dropping resistor at the left, in order to operate from either 120 or 220 VAC . . .where is you ? Depending on the neon lamp - High-brighness...

    Treadmill Controller Varistor blown

    Seeing that they DON'T want us seeing this units part number, and that they possibly used flat black paint to cover its top, vice using a physical wet and dry carbide paper and a wet sanding. Can you confirm that either use of a MEK---TOLUENE---LACQUER THINNER---METHYL CHLORIDE--- XYLENE...

    Is that a fuse or resistor

    Sir pharaon . . . . . . O.K. you are being fine on having the lamp in series with the AC power into the unit . . . .that then will provide "blow up " protection to your unit at power up for initially testing the ¿ repaired ? unit. BUT . . . with your last photo you still have an open AC...

    Is that a fuse or resistor

    Sir pharaon . . . . . I'm hearing like buzz from the circuit but no output Dc Any chance that the secondary rectifier might be bad ? A double sided board in two shades of green mask with that style of vias is not too easy to read , but I made out the rank principals. WITH an additional...

    Is that a fuse or resistor

    Sir pharaon . . . . . Gimme a good closeup of the other side of the . . .double foil sided . . . board so dat I can reads it . . . . .as it is now, a highly educated guess would be that it is a TNY 264. Thaaaaaaaassssssit . . . . 73's de Edd . . . . .

    Is that a fuse or resistor

    Sir pharaon . . . . . Correct, in that units Surface Mount . . . M7's . . .equate in electrical equivalency to a leaded general purpose 1N4007 diode . You could ease the sharpness of bend at the case and form into this *** shape, to get two folded under tabs to solder to the foil lands...

    Treadmill Motor Board / Motor issue

    The board. . . . .got any techno savvy friends ? BUT THEN. . . . .should we also suspect that your units failure . . . should have been at the . . .exact WRONG/ COVID time . Nor, should we also expect that you have the soldering skill set, to be able to desolder, wick the solder from that...

    Treadmill Motor Board / Motor issue

    There is a position for an unused power FET 1 that is being unpopulated but the one just to its right is installed so take metering and put in lowest ohm scale and short probes together to see an expected reading of test lead resistance and then go to pin 2 and 3 of that FET and expect close...

    Treadmill Motor Board / Motor issue

    From your info and without any good photo closeups of the board to refer to . . . . .it would seem that . . . . . AC line power is rectified and then supplied to one or a pair of HEFTY large canned E-caps for the DC supply voltage to drive that DC motor, with a POWER FET being in the ground...

    Hello and How do I check the voltage of this SMPS?

    Sir Switchy Cat . . . . . Is the LED you mention, being the D29 RED main power indicator LED ? If so, its power is being derived from the +15 DC regulated buss being provided by U200. See it in the bottom left corners GREY inset reference snippet, with those 2 parts being RED flagged /...
