I am not sure whether this is the correct place to ask.
However, I may know the place where you can send your TV for repair.

There is one shop in USJ 18 that repair TVs for a reasonable price and good workmanship. You might want to check the shop, it's called Seafield TV and electronics or something.

However, I do not think repairing would be much help because once the IC is damage, thee problem will occur again in the future.

Hope it helps
