A friend gave me one of those nice torchier lamps that uses a GE 55W 2D
fluorescent lamp. It wasn't working so I opened up the ballast and fixed a
few cracked solder joints but still no go, then I found that there's a
number of places in the circuit where if I touch a test lead to it with
power applied the lamp fires right up and will run normally all day from
there. It's definitly electrical because I soldered a length of wire to it
and running my hand over the insulated wire will usually start the lamp.
I've checked all the active components and they seem ok, checked most of the
passives, including ESR on the electrolytics and everything seems to be in
order. Anyone ever run into this before?
