Samsung HCL4715W - no L/R convergence adj. on RED

[427Cobraman]

Hey all,

Working on a Samsung RPTV (HD) with no adjustability
of RED crt convergence. Up/Dn works but no Lt/Rt adjustment.
This is the case whether in user convergence menu or advanced
convergence menu. All other colors are fine. Does this sound like the
convergence IC? Also,when using advanced convergence menu, which key
saves settings? Thanks,

Alex
