Re: Samsung projection TV intermittent shut-down problem
I just called 1-800-samsung & choose the parts dept.
For the replacement lamp it cost $149.99 plus tax & shipping .
My total was 167.08 for Fl. You give them the lamp code ( red sticker on the side of the tv) , they send it out 5day shipment.Local tv repair services can install it for an installation fee. This will save money apposed to ordering through a tv repair shop who charges an order part fee plus etc...

sounds like an intermittent shut down which is heat related. some part , maybe one stuck on a heatsink is warming up and running too much current triggering shutdown.
to find it you can tell what is shutting down with a voltmeter, or you can heat suspected parts with a blow dryer to speed the shutdown .. or freeze spray to see if it goes beyond your shutdown time.
the hlr series had a few problem with intermittent turning off. one was the lamp door cover switch, the other was the thermostat.. neither one is very costly and a good tech should be able to replace bothe parts at the same time..
does the main board have the flyback on it? if so the yokes or CRTs can be intermittently shorting which in turn triggers your shut-down.
turning it off or unplugging just resets the shut down circuit.
