Changed lines 16-21 from:

#	Problem(s)	Cause(s)	Fix(es)	Link(s)	MyPi
1	system unstable, TP1-TP2 voltage low	cheap PSU/ F3 blown /F3 faulty	better powerful PSU / F3 replacement	troubleshooting	made own PSU
2	low power provided to usb devices / power demanding devices (wifi etc.) - system hangs/ LAN problems/ reboot on (over)load	F1&F2 USB fuses	bridge or replace, use powered hub!	troubleshooting	0.5A replacement polyf. bought - yet to be replaced, powered hub
3	system hangs, LAN problems, usb problems	LAN chip overheating due to RG1 1.8V regulator -design issue	heat-sink / RG1 replacement	01, 02, DYI heatsinks	heat-sinks installed
4	unwanted powered usb hub back-feeding (not really a problem, only w. F1&F2)	F1&F2, cheap hub?	cut power wire on hub / add Shottky diode	n/a	Shottky diode bought - yet to be installed + switch (disconnect/shottky/normal)
5	caution when using cheap hdmi->vga converter (unpowered) - overloads Raspi's hdmi, may burn D1 diode or even worse	adapter overloads hdmi	cut power wire in adapter & power separately (from +5v)	01	TODO
