Got my 5089s on 9/25. Noticed the halo on the same day. Call Samsung and they sent someone out on Oct 8. They took the TV. Got it back last night. Still had the halo. Called Samsung, they told me to call the shop that 'repaired' it. I called, they came out. He took about 3 seconds to make a diagnosis: 'Yep, needs a new light engine'
I mentioned to the tech today that I read here that Samsung is out of light engines. He said he knows they are NOT out of light engines but Samsung has issued a directive that all other components be replaced before they authorize a light engine swap. A light engine costs $1200-$1300. I mentioned the DMD board and he said that is the first thing they have been told to replace. He said he is pretty sure that Samsung is getting tired of having to drop $1200 on a repair. He said he should have an answer for me by Tuesday.
I will post follow up. I trust Samsung will do the right thing, eh?
