Can't edit boot/config.txt

[bradleyhollander]

Composit the yellow plug?

[DarkWolf]

@bradleyhollander yeah, I guess that was it

[DarkWolf]

One important thing left:
As the hdmi safe mode is disabled, it could happen that the pi overheats, so keep an eye on it ;-)

I found a great thread for this, so if you need more information you can probably look it up here.

[bradleyhollander]

@DarkWolf can I do this by editing the config.txt on the sd card

[DarkWolf]

@bradleyhollander the config.txt file is located on the boot partition of the sd card
you can find the config.txt file at the root

Edit:
Another addition:
First remove the # of

hdmi_force_hotplug=1

and try it out, if you get no output remove the # of

hdmi_safe=1

[bradleyhollander]

Should I rather get a Vga to composit converter ?

[AlexMurphy]

@bradleyhollander I'm sorry. I can't help you. I only use HDMI screens.

[DarkWolf]

@bradleyhollander The result with hdmi to vga will be be much better thatn composite to vga. If you use the composite video output it could output a really low resolution and the quality is kinda bad...
So try the hdmi "fix" and if this doesn't work at all, I would recoment using a hdmi screen more than using the composite output

[bradleyhollander]

Ok will do thx

Why are people saying to run in safe mode? I understand to troubleshoot but what you really need to do is set the vga to the correct settings for your monitor.

hdmi_group=2 

and whatever hdmi_mode for whatever resolution your monitor is. For me my monitor is 1024x768 so mine is set to:

hdmi_mode=16

[DarkWolf]

@edmaul69 That could be a better solution! I just shared what I die some months ago when I had the same problem.

[bradleyhollander]

Could it be my power supply I use a Samsung 0.7 amp. will that power a rasp pi B

[DarkWolf]

@bradleyhollander You should use a power supply with a minimum of 1A (bare minimum). I would recomment using a 1,5A power supply.

[bradleyhollander]

That's probably my problem

[bradleyhollander]

@DarkWolf thanks for the help! do you think this was my problem?

[edmaul69]

@bradleyhollander that could be your issue. But if you are using an hdmi to vga addapter you still want to do what i mention.
