I'm sorry, but your looking at an Optical Block Assembly which also includes the DM module. Latest figures are approximately $650.00 to replace. I would have called a service tech out to properly diagnose the problem first. Please let me know if you have any other questions.

Hello, welcome to Fixya!
My question would be; how long have you been using the TV and have you every changed the lamp?
If you have never changed the lamp or if it has been a long time since you changed the lamp, then it means the lamp needs to be changed.
The red lamp staying on, also could mean a power problem. But,in any case, go ahead and change the lamp. Hopefully, it should fix the problem.
Regards.
