Hi sir I bought new 5v 1amp adaptor from local market. after that it got stuck on boot logo or sometimes after bootlogo shows black screen... Please help....
It is possible that the box is faulty on its own. If you have a power meter, pls test out the power supply that it can actually supply 1A. Many fake ones fail really short of this so the box might not be able to start if it does not have enough current.
i have vsee box v2 for about month and half now just got back home after 4 days on vacation and now it has zero power to the box .. i tried the wires for my other box up stairs and nothing like it just magically died im pissed ..
You need to isolate if the issue is the power adapter or if the issue is inside the Android box. Make sure to only try the box with an adapter for the same voltage.
No, you can connect them as you wish since this is the AC input from the mains. BTW, they are not diodes but the pins that connect to the plug pins on the case.
Nope it is the other way around. At least in my case and in about 95% of power supplies I've seen, positive is in the middle and negative on the outside. Check the device label, it should be marked.
hello sir my mxq android tv box damage due to inserting 12v adapter instead of 5v adapter, i take it to repair shop but they said need to replace main ic, i want to know which component will be damage most of the time if we connect any high voltage adapter to android tv box or any electronic equipment. i have little knowledge about electronic soldering and i own one cheap multi meter tester.
It all depends on the type of circuitry but it is possible that the main IC is gone if there is no extra protection inside. In an event that there is some extra protection inside like a regulator, fuse, or similar, that might be broken but it is impossible to know without looking at the board.
I accidentally use adapter that has higher voltage than my tv box should. After that it cannot be on using the original adpater. Only detect the power from false adapter. It cannot be turn on. It just blink sign the power connect. Could i fix the problem?
Sounds like it is. Higher voltage almost certainly damages components. Do you have some electronics knowledge to try and inspect it? If not I'll recommend that you take it to a repair shop.
@@tkdmaestro9763 some devices have a fuse at the input that might be burnt off. If you have any electronics knowledge, it's worth a try to look inside and check.
Hey dude a question please.I have bricked my tv box (x88 king) and finally after unbricking it,HDMI output doesnt work (no signal on tv) I noticed most times power supply creates a spark when connecred to socket.Box boots fine though (tested with AV output) Electrician told me that he couldnt find any HDMI damage.Is it possible HDMI no signal problem to be from partially broken power supply?
I'm not sure but I don't think so. If it was partially working out not booting at all, then it might have been the power supply. The spark is commonly caused by the input capacitors charging to fast.
I reckon that the HDMI issue is software related and your new firmware does not recognize it, but it literally can be anything. Did you tried with another cable?
damn why did my box have to die so fast. might as well show me how to make an easy 300 bucks this seems out of reach for me. I hope I can find a repair guy for 50 bucks as 200 is a new machine

I was going to throw my box away and buy a new one, but thanks to this video i only changed the power cable and now it's working.
Awesome! It's great to hear that I was able to help!
You are a very good technician, moreso, a great teacher too. Thank you.
Thank you very much! 👍👍👍

@@TasteTheCode thanks for the reply
Thanks brother I replaced with another brand 5v adaptor... And it Starts working
I'm glad that you managed to figure it out!
can i replace a power supply of output of 5.2v - 2.1A - 10.92w with one of output of 5v - 2.4A - 12w
Yes you can.
I got millivolts reading on multimeter I checked the continuity it's good then what is problem will be
Replace the capacitor on the output. A broken capacitor often fails to bootstrap the circuit.
@@TasteTheCode thank you for the information I will try it
@@TasteTheCode then one doubt, does checking with tester on out it glows its normal or danger
i have vsee box v2 for about month and half now just got back home after 4 days on vacation and now it has zero power to the box .. i tried the wires for my other box up stairs and nothing like it just magically died im pissed ..
There are no rules when something will fail unfortunately...
I have seen bulging capacitors so many time!!! Good safety tips by taping the mains. Suggestion use a heat shrink tube over the hot glue also.
Yeah, that is a good advice. Thanks!
Hi i have T9 device its not turning on please help me
You need to isolate if the issue is the power adapter or if the issue is inside the Android box. Make sure to only try the box with an adapter for the same voltage.
Are there any polarity on the two diods tha you connected to aligator clip
No, you can connect them as you wish since this is the AC input from the mains. BTW, they are not diodes but the pins that connect to the plug pins on the case.
You could have just powered the device with a basic 5v usb A cable?
You'll need to modify the cable to match the plug and also to provide enough current for the tv box.
Which one is negative and positive on the device like the inside is negative right and the outer side it’s positive right
Nope it is the other way around. At least in my case and in about 95% of power supplies I've seen, positive is in the middle and negative on the outside. Check the device label, it should be marked.

In the charger point which is positive and which is negative?..outside one and inside one
The jack is center positive. This is true for more than 90% of the chargers I've seen.
@@TasteTheCode thank u so much
You are welcomed!

Or the tv box damaged already?

Hello how are you did Yu fix your box , I also have the same problem

@@TasteTheCode thanks dude.So my mystery remains 😒

@@TasteTheCode tryied with 2 cables but no lack..Also many UBT versions.Also with BCM.Is there sonething else except these 2?
Sorry, can't help with that. I haven't played much with flashing TV boxes.
My mi box not working
Did you checked with another power supply?
@@TasteTheCode Same here. I tried with other power adapter. the LED flickers but seems dying. the original adapter doesnt show any LED at all.

I don't know ho much a repair will cost you because it depends on what went wrong.
Hello!!! i like your job and that's why i subscribed to your youtube channel. if you want to take a ride and so return the favor - get there
Thanks!
