Having problems with your Flat Panel Televisions ?

My samsung 46 inch LCD also has the problem of no picture, but clear sound. I read all the posts about capacitor problems, and have gone so far as to take the back off and the power supply cover to look at the capacitors. But they all look flat...I don't see any of the bulging noted in other posts.

Answers :

Samsung has had a lot of capacitor issues with some models, even if the capacitors look good they can still be open and need to be tested with special equipment to get to the root of the problem. They had so many issues that they decided to foot the bill in some of the models, you can contact them at 1 800 Samsung to see if your set qualifies, and at the very least they will give you the nearest service center in your area that is authorized.

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
