change the convergence ICs also check the resistors right next to the ICs as 1 or 2 of them may be open as well.

Afraid this is a common problem with Phillips, what happens is the coolant in the CRTs becomes contaminated, this is most common in the Blue and green, So what you have to do is have the coolant changed. Here at our shop we charge $250.00 for this. For most TV newbies this is money well spent. We have see coolant changes go horrible wrong, Anything from a coolant leak, broken CRTs, relay bad convergence after the repair, to the relay bad of a small leak that will destroy or burn your TV set down. Best bet is to get a repair shop that has the tools and expertize to do this for you
