Question about Samsung LN40A550 LCD TV

2 Answers

I have a Samsung TFT LCD 40 inch LN 40A550P3F which just cycles on and off. I get no picture but hear it's little tune before it shuts off again. It continues to just cycle on and off and may eventually come on. Is there an easy fix?

I would inspect the main power supply to see if it has any bad caps with domed tops first, also need to check voltages.
See example of failed 2 years old SAMSUNG due to bad caps in my albums.

I had a problem with a Samsung 46 inch LCD and it had audio and dim light but no picture and found out that the logic board toward the top (inside tv) was bad and was no longer available and the only way to fix it was to get the entire display panel (the logic board came with it) It was not costwise to repair. Hope this helps.
