No... If the red power light goes off then there is a problem with the power supply and/or micro USB cable or excessive current draw due to a fault on the RPi.MeisterKN wrote:I re-formatted the SD card, installed NOOBS. Still the same. Can one of you just plug in Raspberry Pi B without any mouse, keyboard or monitor, just the SD card inside and watch how long the LEDS remain. If they turn off after a minute, it means it is just an issue with peripherals.
There are three ways of getting any initial interaction with the login process(AFAIA):MeisterKN wrote:I have no HDMI monitor, nor am I prepared to use network way of getting a screen.
Thanks for your answers!!!
We've told you that if the Red PWR LED goes out it normally means the voltage reaching the Pi has dropped too low (below 4.68V, I believe). It can be turned off via software, but the normal installations don't do that.MeisterKN wrote:The charger is ORIGINAL all with the green light. Please do the test I suggested. It won't cost you 5 minute time.
With meter set to read voltage, place the red lead on GPIO pin 2 and the black lead to any ground (pin 6), but may be easier to use one of the metal port shields.MeisterKN wrote:Furthermore..., where exactly on the board do You place the red and where the black nodes of the multimeter when measuring power consumption?
The problem is, if you wait too long it becomes more of an argument when you decide your Pi is broken and needs to be replaced.MeisterKN wrote:I plan to buy a monitor with a HDMI connector/connection. However, waiting for these to become cheaper. Where I live the cheapest is around 170 EURO. When the cheapest, say, Acer screen, is around 75 EURO, I will buy, depending whether this problem with my Raspberry Pi is resolved.
What happens if, after the LEDs turn off, you unplug it, wait 5 seconds and plug it in again?MeisterKN wrote:This lasts for about a minute and then, all three LEDs turn off and it seems nothing is working.
This happens all the time I connect it to power outlet.
Had me baffled for a while but I assume you mean soldering not welding, here's some smaller tips...http://www.amazon.co.uk/ANTEX-TYPE-SOLD ... B008KL4H0AMeisterKN wrote:Yes...
When turned on again within seconds, it all works fine for a minute.
The welding I was doing with the first monitor (brand new Pi from UK) was being done with a 3-4 mm head (of the welder). Why do they make all these (even the pro ones) with such a thick tip, and why isn't there a smaller thinner, say 1 mm tip to buy?
So, as you can imagine, it was a mess of enormous proportions, these GPIO pins being so narrowly spaced and small. However, when just making the monitor touch the pins by hand without any welding, I did get a blank, white screen (turned it on). It may have broken (the board) when the monitor and pins were manipulated (I have read this happens very rarely, as these pins are basically not required for Pi to work, and most important point against "self"-mutilation argument, is, that, there are no burned, black, broken, or damaged pins, joints, or any parts on the board).
I am still hopeful that the Pi might have been broken on arrival, that why all the mess with the first monitor, but it could also go the other way (uncertainty being that I did not watch the LEDS at any time) that welding, OR placing the monitor in all possible positions on top of pins to see if it will give any response besides a working blank white screen.
Later, I purchased a bigger monitor (with serial TV connectors) which never showed any life whatsoever, the Pi could have had been broken by then.
So, if it turns quickly on after unplugging, it is not the problem with the fuse??!!
What kind of argument do you have in mind, as I see nothing more but fun in these discussions. Buying a new Pi again would not be a problem as 3 seems to be a way to go now. Waiting is really a matter of customs duty fees, and how much I can spare for a HDMI monitor. Here, all second-handers lack HDMI connector.
I wondered if something like this had damaged the GPIO and soc and it's overheatingrurwin wrote:Which monitor were you using when you were soldering? Because "placing the monitor in all possible positions on top of pins" may possibly have shorted a GPIO I/O pin to a 5V pin.
