The above tv cannot be tuned in for picture and sound i.e. channels cannot be displayed, only a blank raster. The only thing that will work with the remote control is the menu button, i.e the menu is ok on the tv screen , but cannot be made to do anything. I would be interested in knowing where to purchase a circuit diagram/layout through e bay and if there are main differences between the pcb's found in the 26,32,42 inch versions of this range of tv's. Many thanks for any helpfull replies.
