Good spot with the reverse polarity! couldn't figure out why mine wouldn't charge, it's supposedly meant to charge over USB too but nothing. I just took a spare 12v plug, chopped the end and resoldered to make it reverse. Thanks again!
Glad the video helped. Your model must be a bit different to mine because mine doesn't have a USB port. Glad you got it sorted. Thank you for leaving a nice comment.
You need to open it up and look for any signs of damage. I see the P-70 takes batteries, are the battery contacts nice and clean? You'll need a multimeter to test the internal fuse if (it has one).
Thanks Gary, it's been nice to work on a few different things recently. I've been studying switch mode power supplied recently, so I'd really like to find a few faulty ones to test my knowledge on.
SMD fuse from Littelfuse are marked with letters 0 according to a ref sheet I found is 100A @ 250v but if one company use letters i'ed assume others do, other wise it could be a smd 0 Ω resistor but that seems unlikely on that board in the place.
This thing hardly drinks any amps from the PSU so 100A might be correct. If only the manufacturers would label the board with a bit more info. What's your opinion on the fuse blowing. Am I correct in thinking the diode should have protected against the wrong polarity? If so, what could have blown the fuse?
@@PhilipBryden Yes you are correct in thinking that as far as I'm aware. My guess would be the original owner using the wrong V power supply or a issue with the correct one.
Hi Froz, thanks for your support. Pretty simple this one, but I can't complain. It looks like a nice little machine, I use my Brother E110 all the time, they come in very handy.

I have the same problem with an older model P-70. I haven’t used it for so long since I thought I lost it 10 years ago. How can I fix this?

Great job! Keep up the good work
Thank you Mr Thunder. It's a shame my other label cartridges didn't fit but I'm pretty confident it will work.
Nice quick fix Phil I’m still looking for those power supplies I think one is a sega power supply brick and one a Sony

@@PhilipBryden I have loads of faulty boards here ones out of TVs
@@wisher21uk they will be smps won't they. I'll be interested in looking at a few
@@PhilipBryden I will get some together for you, yes smps they’re more fun
@@wisher21uk Excellent, I'm definitely interested in giving them a go. Thanks Gary.

@@PhilipBryden for me its nothing easy cause you used your experience to spot the problem fast :)
@@frozerinosrepairs it was a simple blown fuse. I did have idea to check for shorts before putting the fuse back on tho.
