JVC LT-23D50B with no sound

(1/2) > >>

g*****s:
This set is a good tv,iv only ever had freeview problems with them.Changing caps c940,c912,c908,c934.Has always cured all freeview faults.
CHASSIS  17MB16P-2

It has the external power supply.

Well this one had no freeview,analogue ok.Although i did not check sound.
Changed caps up came freeview as per normal,but i have no sound on analogue or freeview.
Any help or a service manual would be great.

Yes checked them they are just under ic702 they seem ok do you think its worth changing them ?.Just noticed that when you power set up with mains plug sound comes on for about 2 seconds then off again. :41:

There is 5v coming out of left and right speaker plugs.
The sound comes on for 2 seconds on analogue and digital at first plug in of mains power,then no sound on analogue or digital.5v dc still there though.
