I have a Viewsonic 19" display. The board marked Mirage Electronics Co, LTD PI-190DTLB has a scorch mark on it and two caps that looked bulging. I replaced the caps, but the display still will not power on at all. No power indicator light, no display, nothing. I checked the fuse and it's working. This problem happened twice in the past where the monitor would just randomly not power on, but usually it would work fine the next day.
This poster took pictures of this exact board which has the scorchmark in the same exact spot:

The capacitors that were bulging that I replaced were the two within the yellow oval. Would the transistors labelled 3055 6G underneath the scorch marks be the potential issue, and if so is there a part number I can order from digikey to replace them? I'm totally lost on this one.
