I tried a different route between EGLL and EGPH.  It was WOBUN3G WOBUN DCT  WELIN UT420 TNT UN57 POL UN601 MARGO TWED1A. Unfortunately it made no difference. At ESKDO the 752 skipped four waypoints that were in the FMS and shown on the HIS and turned from a northwest to a northeast heading straight to the airport. I decided to land manually but realized I was too high. So I did a 180 out to about 18 miles from the airport where I did another 180, picked up the localizer and landed. So there is a localizer and glideslope signal and the 752 picks it up. But doing a LNAV to capture the signal is not going to work. I have no idea what the solution is. Maybe someone else does. Until then you fly the balance of the STAR and the Approach using heading select mode rather than LNAV. Your route is on the HSI and if you fly that you should intercept the localizer. Or you could land manually or do a VFR.
