Cannot access
Wait what now?????? How are you opening up a terminal on your windows pc like that? That's kind of important info.
Good job
"ssh: connect to host headlesswifi.local port 22: Connection refused" how to fix?
how do we view vnc?
will this work for ubuntu?
how to change call script on gpio button press?
how to change it instead of reboot to gpio 3 second press?
my terminal gives me this error - arsheel@Arsheels-MacBook-Air ~ % ssh-keygen -R raspberrypi.local Host raspberrypi.local not found in /Users/arsheel/.ssh/known_hosts arsheel@Arsheels-MacBook-Air ~ % ssh pi@profgpi.local ssh: connect to host profgpi.local port 22: Undefined error: 0
Am I supposed to leave the LAN country as GB instead of US? I can't get my terminal to recognize the pi and I put the LAN as US. But I noticed you chose GB, but you sound american haha
Hi ! Thank you for you'r video ! But i've try it many times and i always the same error : don't recongnize my password when i want connect ssh... Have you got an idea ?
By default and if you follow the video, the username is "pi" and SSH command is SSH pi@headlesswifi.local. However, if you used another username when you programmed the SSD, then the SSH command needs to use that username. for example SSH UserName@headlesswifi.local . I hope this helps, Mark
This is exactly what I was looking for! I've made some cool things for friends to use but hate asking them for their ssid and password before sending. What if the user takes the device to another house and needs to change the wifi? Wonder if we could program a momentary button to wipe config and/or put back in ap mode for new connection. Maybe even keep old ssid and passwords in case they go between networks (houses), what do you think?
Well now that I look at it a bit it seems to open ap if wifi connection isn't made. So no need for my button. Does it save past wifi/PW of old connections or overwrite?
Thanks
I am struggling so hard with the password stage. I've reset my pi about 5 times now attempting to get the local's password right. I'm about to go crazy. Any ideas on what I could be doing wrong with the password for the SSH?
Hi Zach, I"m not sure which password you are having an issue with. I'm assuming that you are able to get connected to the wifi, but the SSH pi@headlesswifi.local password is returning an error saying you have the wrong password? To be certain, please type the error you are getting. If error is a wrong password, then I have seen this error when I forget to put in the correct UserName into the command. By default and if you follow the video, the username is "pi" and SSH command is SSH pi@headlesswifi.local. However, if you used another username when you programmed the SSD, then the SSH command needs to use that username. for example SSH UserName@headlesswifi.local . I hope this helps, Mark
oh thank the rubber duckie I found this video... been fighting with this bananapi for days to get a headless install to work
Nice !
,200 c is not enough my friend you must do 220 at least
I guess it depends on what you like. :)
110 isn't really "high voltage "
I guess it is relative. :) Working with Mains voltages (i.e. 110v) is always a little scary.
good evening I have a VizioM470NV the screen is dark change the T-con change the motherboard and finally the power card is not heard and the menu is in the dark what could be the problem
Very awesome video! Got my sub. Keep making videos!
Awesome thank you!
Perfection! 👍🏻
My Vizio tv turn on but is not show picture
Super sweet! Need a version for AeroPress! 😂
Working on it! :)
My vizeo has its amber light on but nothing even on a hard start. Plug n unplug. Everything. No flickering on and off or anything. Just stays amber. Should i replace this main board?? And where is the best place to get older style main board. Thanks Jduzs
Thanks this worked for me also.
Glad it helped
Sorry I don’t understand what are u replacing? Or are u just removing and resoldering the same chip ? Please explain I have the same problem with my tv .... yellow light is on but can’t turn on .... thanks for ur help and reply
He reheated the contact points around the chip with a heatgun so the conections will melt back in place. Sometimes the conections will come loose over time if poorly done by the manufacturer trying mass produce products fast and not aficiant, sacrificing quality for quantity.
Just fixed my sound problem using this technique! Thanks for the in depth video. Is your tv still working now?
Yes it is! However, I have since had the chip completely re-balled and resoldered. The heat gun fix worked for a good six months, but resoldering has now worked for more than a year. I really like the solution proposed by wingnetengineer below. Adding a cooling fan to the device will help with the large temperature gradients the package/solder sees and will help to extend the heat gun fix.
@@surfncircuits2916 , Thanks for the info. 11 months later, my sound is still working! My television is located very close to a large ceiling fan, so I think that has helped with any heating issues.
So...I re-flowed my processor at 250'c with an hot air station. Then I added a small chipset fan to the top of the rf shield cage. The issue is here that the back of the tv has hard plastic right up against this area, which allows no air flow. So I modified the back in this area to be open with a fan grill on the cpu side and a chipset fan on the other blowing in cool air though the RF cage. It did not get hot to the touch after this modification and the set works snappy and great now. They really needed a better heat sink as well, but relied on the RF cage to help disperse the heat.
Do you have any pictures. I’d like to do something similar to mine
Thanks for the reply. This is a great upgrade.
This just work for about 1 month and the problem will be happen again. We should reballing the chip.
It work for me thank you alot
Do you need to add thermal paste?..remember that is a power processor
Yes, that best way as you suggest is to add some thermal paste onto the top of the IC to act as a thermal path to the top cover. Although in my case I just used the paste that was already present.
Question. I have a xvt3d554sv vizio. it first started by showing red lines across horizontally and when it would warm up the TV was fine but then the HDMIs went out and that's when I stop using it. do you think I have the same problem or you think it may be something else?
Actually that is exactly my problem, now i'm on the process of fixing it. thanks for you video.
I did everything you said except I left the heat sink intact. I heated it about 25 seconds, re solder back the cover. It works! Thank you!
Can I just put the heat gun to the bottom of the board to reflow the solder ? It's a lot of work to take off the cage. thanks.
*SKIP THE SAFETY DEMO* 3:40
Yeah , he kinda loitered in the AO for a bit before returning to base. 😃
I am having the same issue with my BMW. Even if replaced the light bulb, it only works for a few moments until I closed the trunk. I am glad I saw your video because the issue appears to be the wire.
Thanks for the suggested repair! Heating the chip, under the heat sink on the main board, with a heat gun on high worked for me. It was somewhere over 20 seconds for me. The only thing I have to add to the technique is to place a bit of solder on top of the chip, towards the outside edge. This let me know that the top of the chip had reached the solder's melting point. I had used a bit of solder that had been ejected from my sold-a-pult, because all I have is leaded solder and this is a ROHS device. I used a dab of flux to keep it from blowing away. I am amazed that it solved the problem. This is on my Vizio XVT473SV that has been in service for over 8 years. The picture had turned funny for my wife. She tried to turn the TV off with the remote and button on the side, but the TV wouldn't turn off until she unplugged it from the line voltage. After that the standby light would turn on, but I couldn't get any other signs of life out of it. I was hoping to find a blown capacitor on the PSU, but no such luck. I found the 5v on the standby circuit as it should. I found 3v on the 3rd pin in on the jog wheel power button board. The voltage on the pin went to 0v when I pushed the button in, so it made sense that the button was telling the main board to power up. But the command wasn't coming out of the main board, because I wasn't getting any voltage on the PWR/On pin on the CN202 header on the PSU board coming from the main board. So I gave the hot air a go and hooked the main board back up, but still couldn't get past Standby. Somehow I needed to have fastened all of the mounting screw holding the main board down, not just the 2 I initially tried, that or it just needed some more time to get its bearing, because the next I checked the indicator was flashing between amber and white! So far so good through two power cycles, all buttoned up and put back together. Thanks again for your help!
thanks man!!
