We experienced a power outage at the house, after which the TV has a blue screen for all the inputs. Audio can be heard. This happened once before, a repairman came out and "reset" something and it was fine. Anyone know what was reset and how to do it?

blue screen means no video signal, if the source is on hdmi ensure the cable is rca or in simple audio video jacks which u will have to connect in the dvi input of the tv reason is hdmi means high definition interface and transmits by hdcp like the data of an internet meaning its digital platform which the tv can only process thru the dvi inputs or component y,p,b
The TV is fine. You need to fined the original remote. Be sure you have a cable connection on the anttenna A RF connector. Push menu and find the input. Or maybe input menu...experiment and you will find and correct this. Seen this problem years ago, can't remember exactly what the remote reads. But it should not be serious.
I strongly doubt it's the lamp assy since you can actually see the blue screen. If the lamp failed, you would not see anything on the screen. This blue screen indicates to me that either the tuner is no longer decoding the signal, in improper input has been selected (ie: input 1 is selected while actual signal is on composite 1), or something of that nature. If you are getting audio then the input is selected properly but the video decoder has failed.
If your cable signal is going through a VCR or DVD, disconnect it from there and go directly to the TV (ie: bypass the VCR/DVD). If your picture comes back, there's some kind of problem with your VCR/DVD player.
If you have multiple inputs, try connecting an input signal to another input (ie: video 1, or aux from a dvd player) and see if you get a picture there. If you do get a picture, the whatever input you're currently using has malfunctioned.
