    TV & cable will turn off then on again
    My Samsung TV will turn itself off, 30 seconds later it will turn back on. Then the cable box will turn off, then on again after 15 seconds. There is then a blue screen that says "no single or weak single" then the blue screen begins a series of 5-15 strobe like flashes. Then the picture will return and everything will be fine until the next time (5min. - 2 hours). Cable people have been out 6-8 times and replaced the cable, the connectinons, and four different cable boxes, still the same results. I took off the back and sprayed everything with can air. There has been some improvement ( about 60% fewer times) but are still getting the same as before. I also looked at the capasitors and they were flat on top, so I don't think its them. I also have changed out the wall outlet and grounded that outlet. Still the same.

    Borrow a small flat TV and see if it's the same. If it isn't the box, the cables (inside house and all the way outside to the pole, if you aren't in a city), or your house wiring - what's left? The TV. How old is yours?
