Default Samsung DLP turns off after 2 minutes

Hey all am new to this forum. I am trying to get to the bottom of an issue with my Samsung DLP tv Model # HLS 4666WX/XAA. My issue started all of the sudden. It worked fine one day but the next day it turned on as normal but after 2 minutes the lamp shut off and about 30 seconds later the sound stopped and I got the dreaded 3 flashin lights including green timer light, green lamp light and red stand by/temp light. First step was a new OEM lamp and clearing of the hours as well as a cleaning with a can of compressed air. Thought I would be back in business after that, but still experiencing the same issues. After searching this site and many others I checked the Detector switch and thermastat. I bypassed each with a small wire but still have the same symptoms. My next guess would be the ballast. Can that part be tested? If so how? Is there anything else I can check to save my set? It has a great picture and dont want to drop cash on a new set. Hate to just throw parts at it without knowing for sure what the issue may be. Thanks in advance!!

Welcome to the forum.

Check all of the electrolytic capacitors for slight swelling and replace any that are.

That worked for me on two Samsung TVs.

Well I am way more of a gear head than a tech guy so this may be a stupid question. How do I go about checking the capacitors?? I have looked at the mother board and do not seem to see anything that looks like it is burned or swollen. Upon opening of the back side of TV it looks darn near new. Not even much dust. Should I change the door switch and thermostat?? They look to be cheap on the samsung website. Any direction would be great!!! Sounds like this is a common problem with these units. Has been an awesome tv with great picture. Hate to just junk the darn thing.

A swollen cap will have the side slightly bulged out. Since it's just barely noticeable, you'll have to look closely as it is not a big difference. Check the ones in the area of the power supply which is usually around where a transformer is situated.
