Philips 60PP9100D/37 convergence problem.

Hello . I am working on a Philips projection tv with an unusual problem . I had the convergence board rebuilt (by Modislink/PTS)  and sent back and retested . The tv works fine for 5 to 10 days after swapping the new or old board with each other. All of this is making me wonder if new board is bad or something else I am missing.
