  1. My camcorder won't power on, according to one of the 12voltvids videos, the fuse is blown. https://youtu.be/C5DNd54ksgE
    The service manual shows 6 fuses, are they the ones circled in red? They don't make a beep sound when I test them for continuity on the multimeter. They give me a value of 0.65V instead

    More of resistors, could be diodes.

  3. Most likely those are resistors and measuring 0.65V across them means nothing.
    All the fuses are on the DD105 board, shown at the top of the schematic on page 4-122.

    * WITH THE POWER OFF AND BATTERY REMOVED * a fuse should be checked on the resistance (Ohms) range and for their 1.4A rating should measure less than 1 Ohm. Note that using the continuity range or worse still a dedicated continuity tester can permanently damage the surrounding circuity.

  4. Thanks. I found the fuses on the other side of the board. PS803 is blown.

  5. Bummer I can't find a 3mm 1.4A smd fuse on digikey or mouser. I guess I have to use a smaller one with wires? https://www.digikey.com/product-detail/en/ERB-RE1R40V/P121392CT-ND/6564397/?itemSeq=320431505

    going to 1.5A gives a lot more options. https://www.digikey.com/products/en/circuit-protection/fuses/139?k=&pkeyword=&sv=0&pv1...=1&pageSize=25

  6. You should be fine to use 1.5A, fuse ratings are not very precise in manufacture and in any case have a time element to how long it takes to operate under different overload conditions. They don't live forever at 1.4A and pop instantly at 1.41A !

    Unfortunately, PS803 is the main fuse to the 3.3V supply line regulator so it feeds many parts of the camera. If a new fuse pops it could be difficult to isolate the fault.
