It's the HLS5687, what's happening is after turning the tv on it shuts down after a couple minutes. While it's on I can't access the menu, turn up the volume, or even turn the tv back off. It will cycle a couple times on and off, with out any indicator lights to why it's shutting down, and that's all it's good for now.
Two weeks ago I bought a Philips lamp off of samsungparts.com and replaced the old. I've cleaned out the system of dust, and both fans work. I also jumped the door switch and the lamp thermostat, and it's still doing the same thing. Anyone have any ideas?
