---|---|---|---|---|---|
Schneider | TV9 | Line output transistor short circuit | Replacement did not clear the fault and the protection circuit was operating. C307 0.047µF, 200V was found to be o/c, when removed it had a bubble on the side, it's part of a potential divider network C306 & C307 in series, centre of which goes to the protect circuit, it is hard to get to being right by the line output transistor | ||
