I have a Samsung projection

Best case scenario, The blue crt could be fixed and refilled, and the board only burnt a trace on the board, a chip or resisitor or the like. I worked on televisions for a couple years in a small shop and had seen exactly this problem. We replaced the board and crt, lined (converged) it all up, and the cost was near $300. Probaly a good deal higher now. You could call the local repair shop and run those two ideas past them and ask what they would charger to do that specific work.
