Question about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television
I have a 50" Samsung HL-P5063W (2 1/2 yrs old) which does not power on. . ."Lamp" light flashes for 20 seconds and then you hear PS clicking, repeats cycle 3 times before it shuts off and all 3 lamps flash! Samsung Tech told me to replace lamp. . .they transfered me to local auth. service who told me same and sold me lamp. . .to no avail, then Samsung told me it had to be balast. . .local auth. service guy told me same, sold me balast, replaced it. . .to no avail! So $300 later. . .same symptoms. . .same problem! Local Samsung guy, who also told me, and sold me lamp and balast, wants $75 now to diagnose? I'm alittle upset with Samsung and their local service guy! Any ideas? Thanks, Matt email@example.com
Need to get this checked out my a technician who's got a samsung diagnostic computer...there's also another good resource online. search for Fix Your DLP or go to fixyourdlp.com/blog as they cover topics on Samsung DLP TVs!

You will need to have it diagnosed if you do not have the service manual, or the knowledge of how these circuits work. I can tell you to replace this or that but it would be a guess! You need to start measuring the voltages on the ballast circuit, as I have seen door switches, fan sensors, heat sensors cause all of your symptoms as well. Good Luck

I have the exact same problem, TV stared doing it about 12 days ago, I ordered and replaced the Lamp, it still does the same thing...
""Lamp" light flashes for 20 seconds and then you hear PS clicking, repeats cycle 3 times before it shuts off and all 3 lamps flash!"

Remove the rear cover and check the lamp cover switch. Earlier versions used a black plastic switch holder that may break due to improper assembly. The part number for the holder is BP61-01240A. Newer versions use a metal tab attached to the engine. In this case, improper assembly may cause the lamp cover switch to be extended past its range, either breaking the switch or causing it to have an open contact. Replace the switch with BP91-01231A.
Note that in these models, when reinstalling the rear cover, it is best to remove the lamp cover first, install the rear cover, then install the lamp cover. This will make sure that the lamp switch is properly engaged.
