i have a toshiba p503sgf rear projection arcade machine with a convergence problem. i have replaced the chips but the colours still are not converging (it looks like 3D without the glasses) i have been told it needs reprogramming but have not been told how to do so. can you help??
i have a modrl no 50 h13 and wwhen i first plug it in it looks 3d then its fixes itself with perfect picture for about 5 minutes then switches back to 3d and stays that way
