Well got round to doing my led conversion over the weekend. I did the clocks/dials on saturday, the light switch and door switches sunday and the heater control unit and GID screen today. All went fine until I did the GID screen. I have put it all together and there at are some lights not working, 16 out of 36....removed and had a look, i cant seem to indentify why these arent working. Soldering looks fine like all the others (not perfect soldering but no problems until this lol).

Anyone got any ideas??? or can anyone have a look for me when they got a spare bit of time?
