You need to see the 6230 Schematic, just download from this forum.....Mmmm actually before we repair something, it's nice to know HOW DOES THIS WORK, not only what should I change...There is a circuit who drive the LED in 6230, this circuit is called DC/DC converter. The main IC is N300, and also there are so many component around the IC. So if you ask me what should you do??? You should examine this circuit. But....the most sensitive IC is N300. Just try...
