  • Answer to: enter key doesn't work

    Have you tried taking it apart and cleaning the keyboard mat/board with a cloth or q-tip? Sometimes soda or a sugary drink gets spilled in there and in that case use a TINY amount of water and remove it with a q-tip, then make sure to let it dry for a while. Let me know if it works out, thanks!
  • Answer to: Why is my well kept N64 system starting to shut off?

    If its shutting off at a common length of time from cold, then its probably something to do with IC's overheating or maybe power supply. Maybe try blowing a fan on it while using it and see if it lasts longer. If it does its definitely heat related. In that case it won't be the power supply cable. The problem would be related to items on the motherboard, maybe the capacitors. Its also possible that the heat sink is not attached well enough anymore and it might be a good idea to reseed that. Let me know what happens from there.
  • Answer to: The power button has snapped off the Mino Hd circuit board

    Parts like that are quite hard to find, my first recommendation would be to just find a "broken" one on ebay and part that out. You would be able to find the same/similar part here Mouser.com or digikey.com, but I must say you have to know what you are looking for. If you can take a close up picture of the switch and the pads on the board I can guide you. Also you'll need to have a soldering iron with a small tip, no cheap clunky radioshack one will help. good luck!
  • Answer to: iPad mini 16GB wifi randomly shuts down after screen replacement

    Have you made sure the front panel assembly near the home button has no exposed connections. You can see an example of this here https://www.youtube.com/watch?v=1_hGBxOP... Sometimes those connections can short and cause all sorts of issues.
  • Answer to: Internal battery not powering unit

    My first guess is the battery connector is either damaged or has become slightly unsoldered. I would touch it up with some new solder first. If its not that then its probably circuitry related to whatever switches from battery power to ac power. Maybe a loose connection there, but re-soldering that is flirting with disaster if you ask me. I dunno maybe find one with a broken lens and replace the motherboard if you are feeling up to it, good luck
  • Answer to: Adding an external audio input to this excellent boombox

    I mean if you are not willing to throw down $13 for the schemo then time must not be a big concern, so just start digging in. I've found it pretty easy to find the place to tap into for a line in. That place usually is the fm output buffer stage. Find the main fm chip, look up the datasheet, find its L/R stereo out and tap in after the output buffer, but before the main selector switch or preamp. Then place your own dpdt switch there, that way you then select between Fm or line in. Its pretty much the only way I've found without building extra circuits. Good luck.
  • Answer to: Clean pot on Roland KC300 Amp?

    I've fixed these for years as an official roland repair center. All amps in the KC series have 2 extremely common issues. #1 dirty pots, #2 loose/cold/bad solder connections on the pots, jacks, and interconnects Some KC series amps also get loose solder on some transistors and caps, but I don't remember the 300 series facing that issue. In general its really worthwhile to re-solder everything related to those parts and to never worry about it again. Also use a good deoxit to clean the pot which is best accessed thru the backside of the pot. Hope that helps!
  • Answer to: Backlight not working after display replaced.

    I've never replaced a display on this item, but I would think that its just an led that is lighting the whole thing as I've seen it commonly in low voltage/modern displays. So look for a surface mount led that is probably on the left or right side of the display and thats probably what is out. If you take pictures of the inside I could maybe direct you more throughly. Thanks
  • Answer to: HDMI Cuts out after about 30 seconds of use

    I have a official repair shop for pioneer and yamaha and have heard this complaint MANY times before and usually had a hard time making it fail once I got my hands on it. Yamaha did a study of hdmi cords and found that some manufactures used too thin of wiring to properly handle data transfer between certain items. This MAYBE your issue. What they also found that price made no difference. $100 cords were sometimes worse than $10 ones. I suggest buying another brand at the store and seeing if it solves the issue. Good luck.
  • Answer to: Mackie HR824 Auto Power fail or fail to power on.

    Hey guys, So just to be clear is it the hr824 or hr824II? If its just the hr824, there is a service bulletin for the auto on function failure. This only effects models pre april 2001. So that could be an issue. I could send you the info on the fix if need be.
