Guide posts, not an issue.
With the back of the tv off, look at the lamp connector as it mates with the connector in the lamp hole. Make sure the metal on the pins is clean. Make sure that when the connectors mate, they really mate and don't just push each other out of the way. Those plastic connectors get extremely hot and they can just fall apart from the strain.
Follow the red HV wires to the ballast, make sure they look okay.
In mostly darkness, watch the ballast when someone tries to turn the tv on. Very near to the red HV wires on the ballast there should be a white, small barrel shaped or block shaped device called a spark gap device. If you hear this device sparking/buzzing, and see it giving off a bit of light, that's a sign that HV is present and the ballast is working. The tv (all tvs that use a UHP lamp) will try to light the lamp a certain number of times, (differs by model, between three and five times or so) and each time you should see that spark gap light. If the lamp lights it obviously stops. If it gets to the end of the number of tries, it shuts down and declares a bad lamp.
If you don't see and hear that, then you start testing for voltages on the ballast (380V on the fat black and white wires), and I don't know if you have a meter or feel comfortable getting into that.
If you do see the sparking/buzzing, and there is no problem with the wires to the lamp, then you have to conclude you have another bad lamp.
