Re: SCART RGB output to old TV set

You could try the really simple method. Connect both HYSNC and VSYNC of the adaptor to pin 20 of the SCART.

Re: SCART RGB output to old TV set

Yes, you need between 1 and 3 volts on pin 16 to tell the TV to use the RGB inputs instead of composite from 20.

Re: No signal to Pi 3+ with TV aerial splitter but ok with aerial cable direct?

With the 3 resistor type splitters all 3 ports are exactly the same. The lower loss type using RF transformer do have a specific input port.

Re: Soldering

Many years ago in my job I used solderable enamel wire - a reddy-pink colour - for thousands of connections on prototype circuits, burning off the enamel in solder on the iron tip. More recently I heard that the fumes from that are carcinogenic and such work should be done in the proper environment.

Re: SCART RGB output to old TV set

Your VGA to SCART cable is merely a cable and your PAL TV will only accept TV format signals ie horizontal frequency of around 15625 Hz. Your setup will only work if the HDMI to VGA converter can be made to output such a horizontal rate. VGA of 640 by 480 by 60Hz progressive has about twice that hor...

In theory yes. In practice no. You cannot do it yourself and assuming you could find someone who can source the PMIC and is able and willing to replace it, the total cost of part, transport and labour will exceed that of a new RPi3B+.

Sure, if a 5V 'charger' doesn't regulate to 5V at advertised max. load then it is out of spec. I disagree. If the charger supplied with a device has adequate performance to charge the device's battery then it is not out of spec. That it might have "5V xA" on the label does not necessarily mean it i...
