@abhidev:if ur monitor is still under warranty,do not try to repair/fix it yourself-it may actually make things worse.Try contacting the service centre and ask them to send one of their technicians over to your place to check out the issue.
Today I was visited by a samsung technician at about 9 am-he had with him a new LCD panel which he installed in my monitor.He told me that samsung's official policy is to replace a defective panel only if it has atleast 2-3 dead pixels but he had replaced mine anyway out of sheer goodwill-this sounded too good to be true,i don't know what to make of it-lol.
