Samsung PS64F8500 plasma TV trouble

[bijalwanv]

I have a 4 year old samsung PS64F8500 plasma tv. It worked wonderfully all these years but lately noticed a greenish vertical line from left corner of the screen. After that the TV screen sometimes would refuse to turn ON if the main power supply failed and the backup DG power came ON. In other words any ON OFF operation in quick succession would cause the Standby light to flicker and the screen remaining blank. The sound would be there though. Now since last two days, after we returned from a 20 days UK trip the TV is refusing to switch ON altogether with no sound also. Called a Samsung India technician to check the same and he says the PDP Screen has shorted!!!!!
The replacement part is showing as unavailable in there official website so I am wondering what will happen next!
Been checking online for the part but no luck.
Anyone has any helpful leads to this issue

Contact Samsung if they can help you with the part as well as assess the issue carefully. It could be a fuse or a power board problem but, it is still best to contact the experts about this. Or, if parts are not available, replace your TV with a new one.
