Samsung LED Error Codes? TV keeps shutting down.

[Sev]

I have a HLS5086 WX/XAA
It has been shutting down. Sometimes after a few minutes. Sometimes after 6 or more hours.
I figured it was the bulb. I just installed a OEM Philips.
I blew out the dust several months ago and it is still clean.

The dam thing keeps shutting down when I am not looking. However I managed to catch it in the act twice now.
One time the Stanby/Temp light blinked once. The Bulb light blinked twice.
A second time the Standby/Temp light stayed steady. Nothing else blinked.

Any incite would be greatly appreciated.

Thank you.
