Added Buttons Mini Retro TV

Additions : (1) An On/Off button on the back. (2) A channel change (and other functions) button under the screen (code and idea by Lee). (3) A charging indicator light.

(1) The on/off button at the back can be bought from many places :
(5.8x5.8x7mm PCB DIP Mounting Tact Tactile Push Button Switch Latching 6 Pin)

It is soldered to the T7 on/off switch solder pads using the same method seen in the original instructable at step 15 : https://www.instructables.com/Mini-Retro-TV/

(2) The channel change button is a very old one I bought, which I can no longer find the source. It's 6.2 X 6.2mm H=5.0mm momentary switch. A standard 6x6 switch will obviously fit in there just fine with some glue.

(3) The charging indicator is a small piece of clear 1.3mm trimmer (strimmer) line hot glued to the blue charging light. You can get this anywhere. Example : https://www.amazon.co.uk/Oregon-69-482-CL-Round-Strimmer-Trimmers/dp/B07SQKP6B3/
