Spares or Repair of a very old TV

[OldBloggs81]

I have a KDL40W5500 bought in 2010 and from the flashing of the Standby light (14 times) it looks like it could have a failed TCON unit.

Does anyone know if this old TV is supported or any source of spare parts? I have been sent from pillar to post round in circles by Sony.
