Re: Problem - RCA Cable for Raspberry Pi3 B

Do not use code tags on your links. They are not 'clickable'. You can edit your original post and remove the [code.] and [/code.]. The RPi defaults to NTSC (US). ( sdtv_mode=0 ) If your CRT is Brazilian PAL then you have to make a change to /boot/config.txt and add sdtv_mode=3 See: https://www.rasp...

Bad polyfuse maybe?
If the power supply had a sudden fault that it did not repeat, it might damage the next Pi when it does.
The power supply is ok, i put in another PI and don't show the ico..

Re: Raspberry Pi3 B Low Power ( I use it for 3 years )

Be aware that your Pi appears to be a Pi3B. The stock photo you are using is a Pi2B. The only full schematic published was for the PiB (original). Component type, number, position and function may not be compatible across boards. Make sure any repair you attempt is based on information relevant to ...

Re: Raspberry Pi3 B Low Power ( I use it for 3 years )

Sorry, I can't make any informed predictions, but: It might work for years with no problem other than the low voltage warning. Or it might fail altogether tonight. Least likely is that it might just recover. I think you have done the best you can with your tests, far better than many reports here. ...

Re: Raspberry Pi3 B Low Power ( I use it for 3 years )

4V976 is within tolerance. Should not produce a low voltage warning. 3V14 is not correct, should be 3V3. It looks like your Pi is dying. BTW, you should put the black probe to meter "COM" and red to "V". Then the readings won't get the minus sign in front. I try again for 3.3 with corrections, but ...

Re: Raspberry Pi3 B Low Power ( I use it for 3 years )

I agree, it looks like the Pi i at fault. Put your voltmeter on the first switch position ("V") and measure the 5V and then the 3.3V pin on the GPIO connector with the other lead of the voltmeter on the GND connection - when the lightening bolt is on. 3.3V https://i.ibb.co/q1ZG7Rr/3v.jpg 3.1/3.2V h...

Wasn't it an issue for the 3B, with certain power supplies? Also remember that, some power supplies will state 5V but are actually less once they are actually under load.
OK, but do you read my up post?
