Just wondering if anyone would be able to help. I'm working on an inverter board and want to replace what I think is a capacitor. Thing is, I can't really find out what it is exactly. Markings on it:
(no clear polarity)
H683
2N47
Markings on the board which it is on are C{number}, and seeing as it is near an inductor on an inverter I can safely assume it is a capacitor. However not a clue which one. I thought it would be H = 50V (or 3% margin) with 68 * 10^3 pF, but when I replaced them with a 0,47uF 100V (electrolyte) capacitor the board doesn't function. As I didn't know the polarity (the markings on the original are not clear) I swapped them round and still got no result. I'm baffled at what these things are and perhaps they didn't even need replacing.
If I can't replace them (the backlight of the unit has failed) I will probably attempt a LED backlight myself as I don't really feel the urge to now fix this inverter (backlight operated sometimes, but then always flickered and died soon after. Could be the inverter was dead, now it is if I replaced the part wrong, or the tubes).
Any help would be appreciated, perhaps Originality or FAST know this ?
