The team at Kodi Fire IPTV strongly suggests that you use a VPN at all times.
Be it for browsing, watching Kodi, watching IPTV or anything else – the one that we recommend is Hidden Router. They provide you with very fast speeds, that can reach over 400Mbps, and their VPN service is as low as $6 per month (when paid for 2 years)!
Grab your own Hidden Router and regain your online privacy now!
This helps make sense of the phone call the other day 😉
When cables are manufactured they get stored on cable drums, all wrapped around, so the wires have a tendency to want to wrap themselves around again – kinda like a memory effect
Thanks for another good video. keep it up old man!
Enjoy to see how you can use electronic repair experience in a universal way and apply it on a wide range of products. Great educational videos.
Interesting! Thank you.
This is by far my favorite video of this channel. Enjoyed every minute of it. Thank you so much for your lessons.
This video needs a part 2 so bad.
I would like to see you try to repair the second one. It is a pleasure to watch you repair electronics.
Yes, I would love to see you fix more of these. Any fault finding videos are welcome regardless of the equipment. I always learn something in every one of your videos. Thank you very much for your time!
Amazing diagnoses and detailed working of ohms mode and usage. Friction is the answer to the question of untangling. Once the wires are tangled there is too much friction to untangle themselves. Great video Rich, i learned a lot. Thanks mate.
no boot with both leds lit on eth port indicate failure at early bootloader/initialization stage on most broadcom and many other socs, that 25q032 spi flash is storing the bootloader, good intuition. you should be able to read it with ch341a programmer
Like to see the others repaired as it adds a bit of variety. Cheers
Hi, it would be interesting to compare the voltages on the now fixed one with the "semi" working one, whether there are any differences.
I think the flux crystalizes and forms a shield around the unsoldered components. Thats my reasoning to why you couldnt read the short on the capacitor when you took it off. I sometimes have the same issue
I wish you'd do some of your video cards with cheap video cards. I'm trying to learn from start to finish on video cards and I can't afford to purchase expensive video cards to wreck them. I don't mind messing up three or four or five or six cheaper cards but when you pay 10 bucks a piece for a card that's okay but $100 a card is not doable.
Situations like that call for a thermal cam, saves a lot of time.
Outstanding video !
Yes please ☺️
You have my vote to work on the others.
Good evening. Cables follow the third law of Thermodinamics: Entropy increases ever and ever…and since Entropy is a measure of disorder, you can do the math…😄😄😄just kidding!!
Richard ? hope thats correct, just wondering if you could provide some info on the microscope you use ?
Another video of throwing boxes and electronic devices on the table and they wonder why they don't work…useless
Yeah would like to see u get some 250 boxes working I've not subscribed yet but when u do them I'll subscribe as I have had a few of them boxes just die with no power wouldn't mind I only binned them other day wish I'd of kept them now to have a follow along with you. Would be great to see you fix the other boxes tho mate.
Don't know why but I always find tv boxes brilliant to watch been repaired out of all tech mine is android box mag box tvip box
Hi again. I have 2 3010D power supplies. At 1 volt I can only get .1 or .2 amps. Lower voltage and I am lucky to get .1. No heat at these low amperage's. I saw you put 5 amps into a video card at .8 volts in a video. What would you suggest, get a different power supply? Suggestions??? Thanks, amtpdb.
i'm having the same issue.. i have the mag 322 i need some help.. can i send a message to you?
So you removed the two faulty capacitors without replacing them and it just work fine?
If you look when you plugged the power in and move one frame at a time (the < > buttons) yo see a spark fly out of the cap ! its only 1 frame in length and a few more frames on the magic smoke appears. Great tutorial…..cheers,
When i get that smd with 6 pins??? Up on it are only 200 nothing more ? Anyone can help me???
