Samsung dlp hls4666wx TV. After a power surge, my TV shuts off after about 4 minutes. The stand by, TV, timer lights flash...manual says it's the bulb or fan. Only, I bought a new bulb, and noticed both fans are working. Still does it. It makes a small pop them hiss or buzz sound when it offers the bulb down. The power supply and ballast look ok (circuit boards). Perfect picture and sound before shutting down. I've heard there are 3 fans but only see two. Could it be another fan I don't see? Or
Samsung PN50B450B1DXZA will not power up. When I try to power it on, it makes a clicking sound and then nothing for 10-15 seconds and another clicking sound. The Red LED on the front flashes when it clicks but nothing ever appears on the screen. I removed the back of the TV and inspected Capacitors but do not see any that look to be bulging. When I try to power it on with the back off, I see a green light quickly flash on a logic board just below the power supply board. Are these clues helpful
