The ticking noise usually comes from the power section of the tv. Usually it is a capacitor failing. As far as the cost of repair this can go either way ie cheap or expensive. It will dpend on what exactly has failed and if it requires a board replacement or just a part.

I'm going to assume this isn't under warrenty anymore. It is covered if it is. You need to get some repair estimates from Samsung and any tv repair shops. Then keep and eye out for a replacement. Make sure you include any shipping costs or other costs when you are totaling up the estimates. If it gets close to the replacement cost then you will have to choose if you want a new tv or have a repair done.

When i turn on my samsung LN52A550 it usually looks red and then gets lines across the piture but after about 20 minutes it clears. Anyone ever hear of this?


I had this problem on my Samsung set too, along with capacitor issues. I fixed this issue, though, by disconnecting and reseating the long ribbon cable between the main board (the one with the cable jacks) and the LCD controller board (near the center top of the set). On mine, I had to pinch ears on either side of the connector on each end to remove the connector, and then I clicked the connector back in, and viola, no more lines! This is likely due to minor corrosion on the connector pins, and reseating clears the problem. If it doesn't, you may have a bad LCD controller board, which can be usually found on ebay.

do you hear any click click sounds? A common theme with Samsung. My tv did click and it was the capacitors.

http://www.youtube.com/watch?v=tK7zFBBU6p4&feature=related I watched a few of these and was able to see my tv had 4 bad capacitors, de-soldered and replaced them for under $5.00.

SAMSUNG SERIES 5 550 THE TV WILL TRY TO COME ON AND THEN SHUT DOWN AND START OVER.


Most likely failed capacitors in the power supply. I recently had the same problem with my 26 month old Samsung LN46A750. Samsung paid for the installation of an upgraded power supply board.
