Sony India — Service

I contacted the nearest sony tv center regarding the motherboard availability. They are saying it's not available and hence asked me to sale the tv and that's not right to do as only motherboard issue has been identified. Actually some time back during covid lockout motherboards weren't available but now I can see that motherboard for my tv model sony bravia kdl w950a is now available on some many websites for sale. But still sony company is not helping me. Please look into this.
