No image just audio on Samsung Plasma PN64E550D1FXZA

[blake.s]

I have a samsung plasma PN64E550D1FXZA. At first the tv would work for 30 minutes to an hour and then picture would cut out but would still have sound. Now, tv only produces sound with no picture when the tv is powered on.

Tv is functioning now. Will see how long it takes the tv's picutre to go away. Kept the tv off and unplugged overnight. Does this sound like a common problem?

Edit: After about 15 mins, the picture went out and sound is still working.

This is a common issue with these models. You have cracked solder joints on your power supply board BN44-00515A. If you have the ability to solder, I recommend you simply reflow all the components that are screwed into the heatsinks as well as any other components near the heatsinks that might share the same copper pads.
If you do not know how to solder or are not comfortable with that kind or work, you can always send the module out for repair as well

Let me know if you have any additional questions.
