40 Days out of warranty and my screen went Green last night. From perfect picture, to green to no pic. Cycled power, came back all green. Unpluged over night, same results. I'll start with the service manual and keep you posted. Any suggestions would be appreciated. Should add this is a HL-T5687SA, not sure the firmware rev nor hours total on the set, Christmas gift to self last year. Assuming I can determine both in the SM? Will read posts regarding SM access and update.
Update: Feed it an All red screen using the WiseLink, Red is dead. Since I use to be an electronics guy a long time ago in a galaxy.... I poped the back off the set. Had the LED driver unit, or whatever it's called, on my Kitchen table in 20 mins. Nothing to this thing. Used my trusty DVM and some nice data from Luminus, http://www.luminus.com/content1092
and determined that the RED LED IS DEAD. Now maybe bad LED, maybe the driver circuit took it out, not sure. Think these things are sold as a set, any input on that would be apreciated. Found a possible resource on Ebay, but I can't be sure it's the right part, or color.
Anybody out there have a service manual that would be willing to share the Samsung part number for the RED LED light source?
