Vizio D65u-D2 works on standard picture set to medium, not on vivid

Vizio D65u-D2 turned the setting to standard and medium. Picture loss issue resolved. If I set picture to Vivid, lose picture after a 5 to 10 minutes with audio only. Turn off, turn on, issue repeats. Ordered the power supply board to see if it allows me to use Vivid setting without loss of image. If after change issue continues, what is best bet for next board to change?
