If lamp ballast have damaged, 3 binking of standby light can occur.
After lamp replacement, lamp run time should be reset. For this adjustment, you have to enter its service mode. Service mode window is quiet different to that of normal user window. Without proper knowledge, entering into service mode, and adjusting data values to this window may make TV beyond repair. It will be best to contact any experienced service person to do this.
