Phillips 28CL6770 28" TV-Stuck on stand-by after repair

[garswood]

Having identified board causing my intermittent power-down and soldering all large through hole pins (on line xformer, conectors etc.) it now won't power up fully - can't get past standby condition. Convinced I have not done any damage whilst soldering.

Read somewhere that TV may be in a 'service' mode after board has been disconnected and needs re-setting, but don't know how. Does it need a code (like car radio) from the remote or certain combination of buttons pressed.

Any help would be very much appreciated.
