How did you know 10ohms was the correct value? Sounds like a problem with the power rating (not resistance rating) chosen by the original assembler. Maybe needed that (50ohm or whatever the original was) resistor to keep from blowing the transistor, but should have been a 2ohm power resistor instead of a cheapo half-watt resistor. Also are you in the UK or the US. If you use a US bulb in the UK it blows it because the voltage is too high over there.
This happened to me but the ballast was fine. i experimented to see what would happen if you only connected one end of the tube but this specific ballast needs both filaments to be connected. the tube i had was dead so i shorted one end and connected the other to the tube. the filament lit for about 2 seconds then it shut off and a transistor blew on the ballast with sparks and it scared the s***out of me. no resistors went up in smoke.
@poiiihy hehe, yeah, I regularly take apart electronic things and they have funny smells even when not broken. I bet a transistor or resistor blew and stunk up quite alot.
@MrGerbilBrain they always have that smell. even working ones. i sniffed a base of a cfl with a hole in it and uh, u know, stinky plasticy toxicy smelly
@RODALCO2007 well see the thing is I dont have a MOT yet, and I took the inductor and capacitor and diodes and got rid of the other bad parts. but a mot would be fun :) I did almost get a mot but the damn guy didnt want me to take the microwave home cause he thought it was too big? grrr... oh well, maybe I will have one after 5 years or so :S or maybe I could go to the junkyard instead, I dunno, but that gives me a good idea for like finding old welders and stuff with big transformers! :D
seems like more of a fire hazard then incandescent lights f.u.k CFL's thier also harder to recycle and they contain more toxic c.r.a.p then a regular light
All CFL's are made like this now, i have like 8 gutted ones; one has a filtering foil cap vented / exploded, one another has both two transistors split in half. A few has slightly bulged electrolytic caps.
Be careful! The big Capacitor holds the voltage from the mains, that has been rectified. so if you have 120V (220V) Mains, there will be 170V (311V) DC on it.

And that my friend, is why you never try to repair a CFL lamp

the ballast has a toxic smell that made me feel funny when i opened it up.

@MrGerbilBrain smell a base of a cfl to know what I mean.

Connect (the whole lamp) to a sodium lamp ballast and pop it (Try only in a ventilated area:the tube has mercury inside of it)

@MrGerbilBrain: Was that one of those fish tank cfl's that can be bought at WalMart?

@lightbulbcollector1 no, its a regular cfl

Now finish it off with a MOT transformer.
those boards stink when burnt out.

I hope you wear safety glasses & have good ventilation when you're experimenting with these things. Safety first is a good rule.

@michadergrosse Yep, I charge up large caps with 200volts, and discharge them, making lots of sparks for fun.
MrGerbilBrain 1 year ago
@michadergrosse
The ballast lowers the actual voltage the inverter driver and the big cap gets but yeah better be careful with that.

probably a shorted switching transistor causing this. or (worst case) shorted transformer.
they use "fusible resistors" instead of real fuses because they're cheaper.
also: next time, turn macro mode on in your cam's menu.. :P
