After some help with this Ly1911WCW tv/dvd combo i have. Got given the unit with no picture just sound (only on DVD as could not access menus with black screen). Replaced PSU/Inverter driver as backlight transformer U/S.
Once working no access to any tuning menu's only audio, picture and some items in function menu. Managed to get in to factory menu with 8893 code and reset eeprom. Can now tune std TV but still no tuning or other functions in DTV mode just black screen with DTV in top right.
AV board is Haier MST9E19B (P/N 0091801317 V2.0) software Version L-M19B-BOE190.D.UK (06/12/18 17:50:24)
