I've repaired about a half-dozen of these chassis at this point, and one major worry area I've come across are the 8 182 1.8k SMD resistors underneath the flyback, R533-539 and R514.
The board is almost always scorched here, and in one case, a hole was burned clean through the board, needing a whole lot of extra work to repair. The solder on these resistors is usually pretty melty looking, but the resistors themselves test fine.
Is there anything I can do to help prevent this? The only idea I really have is resoldering with a higher melting point solder to help it not get melty during operation, but I'd be happy to hear any other ideas.
