Scart connection works fine, it even automatically switch to the ext; unlike HDMI, i have to use remote to switch to HDMI channels.
However, i have to put up with it as the picture quality is much better than scart.
Also, While i was searching the net to find solution to my problem. i saw one of the solution is to switch the HDMI cable ends. To me, it doesn't make sense but i give it a try. And to my surprise, it worked!
i don't think there is any set incoming or outgoing end on the cable. Why? But main thing is that it is back on working condition now. That put the smile back on my face and thank you to give advice.
