You might have a bad regulator on the signal board or a bad button on the front of the tv. The AV RESET button will make the screen go black and if it is malfunctioning can cause this symptom. Bad solder (cracks) can also cause this. Lastly I have changed a few regulator for different problems. Near the back left side (while behind tv) on a small heatsink. Goodluck.
The screen wont go black, however static appears as if the cable was unplugged from ANT-A. After several minutes of this off-air static, the signal comes back and all is fine. Driving me crazy.
I'll look into this regulator board though.
no, it won't be a regulator. are you sure it's not the signal source? have you tried another tv on this cable line. it's seems odd that it would just cut out the way you describe, definitely not a common failure of this set by any means.
Yes, tested all cable connections, etc, on other tv's. I've never seen this either.
Cable from Time Warner is coming into house and plugged in to "ANT-A" (or B). TV is turned on and on the correct input/source. Static appears and the audio from the signal is distant and garbled, although one can tell that something is there, as in signal. Then, after a few minutes, bam, all is fine, picture pops in, sound is fine, etc. Now, two things can happen, I can change the channel and sometimes this pops the signal back out. I get static again for a few minutes (up to 10 minutes) until the signal magically pops back in. Or, 2, I will turn turn the tv off and back on. When it comes back on the same thing happens all over again.
Checked the signal on 3 different tv's. All of them work perfectly. No problems.
is the tuner physically broken? will it come and go if you jiggle the cable or if you kick the corner of the tv?

Usually consumer described bowing is bad solder connects
on pins of convergence IC's. If the effort is made to pull the center PC board out,then replace both Stk392-570 IC's for
durability.
Note: V-Pin amp and pin out relates to left/right side bowed-in
issues,a problem not usually found on your model.
