Which lcd monitors have TV /Video game inputs?

Losing audio and video on Sony Grand Wega 55" LCD Projection TV?

• We are losing both Audio and Video (no picture and no menus) on our Sony Wega KDF-E55A20 LCD Projection tv. The power light remains on and steady. If we turn OFF/ON then it's fine. After doing some reading online it seems some people experience something similar and that it would come back on after a while. It happened again tonight so we waited. We heard a sound similar to the retracting of a lens (like on a digital camera) and then several seconds later picture and audio come back. The whole period lasted about a minute, maybe a little longer. This has happened with different input devices (DVR, game) and input ports, so isn't tied to anything specific there. This has happened maybe 3 times in the last year but 6 times today. I was thinking maybe the lamp, but am confused why a bad lamp would also cause the audio to drop. Please help!! Don't want to spend the $$$ on a lamp if something else is going on. Sony support has been next to no help and very frustrating to deal with, clearly not reading my email as the first link they sent me was what to do if your tv doesn't have power (no joke). After I responded to that email they sent me a link about what to do when the standby light is flashing (still clearly not reading).

• Answer:
