Three to four times a day lose picture and need to reset top box, box has been replaced twice.
Would need more detail as to your setup. Box model, method of connection (HDMI, Component, Composite, RF), is connection direct or through another device (like an AVR),TV type, etc. Withoput more information any suggestion would be a total stab in the dark (and most likely worthless).
HI DEF DVR MAO820CAV170 this box is connected directly to the Toshiba HD TV. This problem was fixed during the summer but started again in Dec.
I do not have this problem with the other two sets.
