| Dear friend, I just today repaired one Bush WS6671 (11AK19 Chassis) with same fault. I found o/c resistor 27 Ohm, I don't remember circuit diagram position but it is very near to connector for deflection.
Dear friend, can you send explain how get "service menu"???
Thanks in advance and best regards from Zimbabwe, Africa.

| Hi chris thanks for the reply.D611 & D612 do read ok but unfortunately I cant replace them because I dont know what type they are!There are no numbers on them & the print on my circuit diagram is bad.All I can make out is they both start with BY2--.Do you know what they are?I replaced hv cap (C626 I presume you meant) but it didnt help.If it is the e/w coil L604 faulty do you know where I can get one (UK) |

| Hi Svetozar,the resistor you suggested was one of the first components that I changed for the original fault - low width with pin cushion distortion??!! But any further suggestions will be gratefully received.To enter service mode,first enter the installation menu then press 4,7,2 and 5 respectively.The info I have relates only to geometric adjustments.I dont know if the sound system can be changed.Thanks anyway for your reply |
