Panasonic LCD TV Flashing Strobe-like Picture?

Question

We have a problem with our Panasonic LCD TV. It's a 32-inch LCD TV (Model #TC-32lx600), with a Time Warner HD DVR Cable Box hooked in by HDMI cable. When TV turns on, the picture comes up flashing (like a strobe light effect), and the picture keeps moving up the screen like on old flim strip. Other connections like component did not work nor any other inputs like DVD Players and a PS3 (same effect). Please help or offer any suggestions rather than buy a new one or get it to a repair shop. Had this TV for 18 months.

Answer 1

HDMI can exhibit strobe-like flashing...

I suggest unplugging both the TV set and the Cable box to reset both computers....leave it unplugged for 5 minutes.

Then plug the cable box in first, followed by the TV set. Give it two minutes, then turn on the Cable box followed by the TV right after it....

Why all this "do this first, then this next"?  To assure proper handshaking between the Cable box and the TV set.

Now, if you still have that strobing problem at this point THEN you KNOW your TV set needs a new signal board....
