The power supply was replaced. Worked great the first day/night. Now when you turn the TV on - gets power, gets a picture for about 15 seconds then goes black. Will work after numerous attempts and turning on with the remote.

Hello.The screen goes black means that the backlights of your LCD is not working.Maybe the problem is the power supply or the driver board of the backlights.They shutdown because there have a shorted parts on the circuit or power supply.
Did you try to reset the power and turned on and get a picture or every time that you reset the power it will get a picture and the picture goes black?

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

check if the back lamps are still on when you lose image, all you have to do is get close to the screen and make is totally black and if is not that means you have a back light working, but if the back light is gone you may have a defective panel.
talked to samsung TA about the same problem I had and the recommend to replace the power supply first to confirm a defective panel because a panel is quite expensive

One of two symptoms on this model (LTV-32W6HD)

No picture;
OR
No picture but sound is OK.
1: In both cases replace ALL the electrolytic capacitors onthe output side of the power supply. This should get the power switch to worknormally.
2: Replace the small tiny wee little tiny small 2.0A fuse onthe inverter board labeled F1.
This is the small black fuse, not the slightly bigger whiteones labeled F2 and F3.Ta Da...all fixed.
