If this problem happens after such aive mins and it is consistently giving that same problem to every time the set is turned on then it is a cold solder in your circuit of the video.if it gives that problem on start up ten the video amp and related circuit should be checked.have a tech check your tv.good luck.

Remove the back panel from the tv where the input jacks are located. You will see a red power wire. Just above that and to the right approx. 7" or so you will notice a [_] shaped metal shield surrounding a cgreen/gold capacitor. You may need to remove the plastic cover that is located directly above it about 6-7" in length to gain easy access. Run your finger over the top of the capacitor. If it is beveled rather than smooth you have found a definite solution to your problem. The part number located on the board is CP150 16v 2200uF capacitor. It will look like a tall cylinder. Good luck!!
