I purchased one of these at Walmart for x-mas and the video screen stopped working. I took it back and exchanged for another ( same one) and now this new one intermittently does the exact same thing. It's not over heated...it just wont show the picture on the screen. I can hear it running and hear the audio. Is it me? Or are these just faulty dvd players? I've looked at the manual and cant find anything with regard to this problem in the trouble shooting section. I've tried different dvd's...still no picture. Then suddenly, like today...I put one in to try it and it works. frustrating! anyone else having same issue?
