==== Colour Picture (RGB) ====
This schematic requires a TV with ''RGB input'' on Scart Connector (back in the 8bit era, many TVs have had only ''Composite input'' implemented on Scart connectors- nowadays RGB is also supported by DVD players and 3D gaming consoles, which is possibly increasing the chance to find RGB support on modern TVs).
The 9V and 1.5V batteries are optional. They may be helpful to switch the TV to RGB mode automatically, without needing to activate it via buttons on the remote control. Instead of the batteries, you may also extract the voltages from elsewhere (like the CPC supply), valid are Pin8 = 9.5V - 12V (9V is actually a bit too low), and Pin16 = 1V - 3V.
They may be helpful to switch the TV to AV and RGB mode automatically, without needing to activate it via buttons on the remote control.Note that AV input can be usually selected using the remote control, while manual RGB input selection is only available on more recent TVs. '''Battery duration''': since Pin 16 (RGB input selection) has an input impedance of 75 Ohm, it will drain a common fully charged 1.2V ~2500mAh AA battery in about one week, if left connected permanently to the TV set. {|class="wikitable"|+| Pin| Voltage| Function| Note|-| Pin 8| 9.5V - 12V| enables AV input| 9V is actually a bit too low|-| Pin 16| 1V - 3V| enables RGB input||} [[Image:CPC2SCART - RGB.jpg|600px|thumb|none|Schematic for a CPC classic connection to a TV-set (Colour Picture)Note: The left and right sound channels are swapped in this diagram]]<BR> ==== John King's Comments about Scart Connections ====<BR><center><font color=green size=6><u>SCART PLUG CONNECTIONS.</u></font></center><BR>'''The following information relating to the Scart Plug (Euroconnector/Peritel) could be found useful when concocting leads to connect your PCW, CPC or Spectrum +3 to a Television or Video recorder.

Bug: The 1.5V battery shown in the mono schematic is nonsense; for composite, Pin16 should be wired to GND, not to 1.5V.

==== Alternative RGB Wiring ====
[[Image:Alt_Scart_Connect.PNG|600px|thumb|none|Schematic to connect to RGB without requiring a 1.5V supply (Colour Picture) The 9V supply (as shown above) may still be required if the TV-Set has no AV Source Selector. If you experience picture flickering or the TV OSD appears intermittently while the CPC is connected, add a 100µf capacitor (optional) as shown above, this should resolve these problems. This setup won't work with all TVs. Some small 15" LCD TVs (for camping) have been reported to show ghost images with this setup, where a greyscale image is displayed besides the RGB image.]] '''The alternative wiring has been reported to often not work with modern LCD TVs or Scart2HDMI converters. In those cases often a (bad) gray scale image will be displayed or there will be no picture at all. It is recommended to no longer use this wiring and instead provide a real 3V voltage on pin 16, e.g. by connecting it to the 5V power supply with the help of a simple voltage divider resistor:''' [[Image:Cpc_to_scart_rgb_sw.png|600px|thumb|none|Schematic to connect to RGB on a TV set without RGB switch.

Perhaps I should start by saying that the tasks to be undertaken on this page are not for those of you without electrical and soldering skills, but for the competent, the following circuit will give a quality picture and stereo sound through a television set from an Amstrad CPC6128 Plus, a CPC464 Plus and GX4000. The lead has been tested on a number of different makes of TV (with complete success), within, the age range of 1 to 4 years. I have been unable to find anyone admitting to owning a TV without AV switching so no provision has been made in the offered lead for these old obsolete televisions.<BR><BR>
<ul>
<li><b><u>PARTS AND TOOLS REQUIRED.</u></b>
<li>Scart Plug (also known as an Euroconnector or Peritel Plug).
<li>8 pin male DIN Plug.
<li>6 feet of six core cable.

<BR>Just in case it is not obvious, use the six core cable to connect the DIN plug video/RGB connections to the Scart plug and the twin screened cable is for the sound connections to the Scart Plug. Now that the Scart lead has been made up following the above diagram, tape the two leads together (or use cable ties). Now you will need to turn to making a suitable power supply for your CPC Plus/GX4000 machine. <BR>
<BR>The GX4000 offers a Scart socket for connection to a TV (The Pin connections are listed wrongly in it's manual!). You will need to use the power supply (if not already defective) as issued with the machine, when using a Scart lead.<BR>
<BR><b><u>POWER SUPPLY.</u></b><BR>
You will need to find a Power Supply Unit giving a 5 volt regulated DC output. See this Wiki article for more information: [[Power_Supply_for_CPC_and_CPC_plus]]<BR><BR>
It is well worth the effort of making up a Scart lead and power supply unit for your CPC Plus/GX4000 machines, as the quality of picture and sound far exceeds that obtained from a Black/White or colour monitor. Games are given a new meaning when played using a 32 inch wide screen Television.<BR>

==== Black & White Monochrome Picture ====
Info from OCT: "I recall that when Amstrad Action came up with the proposal for a SCART cable back in issue AA41, numerous readers wrote in suggesting that resistors (most commonly: slightly below 330 ohms) should be connected "in series to the colour signals [...] for improving picture quality" (AA45, June 1989, FORUM, p. 23), so they seem to have appeared overblown in comparison to the CTM644s' back in the day."
The goal of that improvement is unknown - it might alter the medium-to-bright ratio, or, it might be simply intended to reduce the overall brightness (such like when the CPC picture appears brighter then normal TV programs). The voltage/brightness output by the CPC is actually higher than normal SCART voltages, however, the voltage drops when the TV applies load to the RGB pins; that load may vary from TV to TV, and so, the resistors may be needed only on some TVs, but not on others.
