My Panasonic CT27633W 27" TV many times will not power up. No lights, no picture, no sound. Sometime it seems to work just fine. Other times I have left the TV off and it will come on by itself at a later time. I have replaced the fuse (even though it tested OK) but no change. Any suggestions?

Is this happening when you just use the remote or does it happen when manually turning the set on also? If it is happening only with the remote, it is probably only related to the remote circuitry. If it happens with both manual and remote, it probably has something to do with the "startup" circuitry.
