It is telling you that you need a new backlamp or that the power supply that feeds it is out. It could be bad Chinese capacitors or you may actually need a back lamp. The hint was when it was working did the side edges have a darker brightness to them? If yest the lamp is needed. If no then the capacitors in the backlamp supply may have decayed.

How can I tell if the lamp still works? I dont have the projector to text the lamp so I'm wondering if there is any way to tell if it still works.

Because the lamp does not have a filament, you cannot run a standard continuity test either. You really need the correct power supply and ballast to see if it still works. Many old lamps will continue to work although the lumen output will be significantly reduced.

Can I reset my lamp timer without replacing the lamp?

That should be fine to do. Even if the projector did alter the current based on lamp life, the worst that could happen in the lamp would burn out completely. A good projector should have a safety circuit with a fuse to prevent damage to any internal components. You should be fine.

Did you use an original Sony lamp? If so, I would say that the problem lies with your lamp ballast, or lamp power supply. Also, keep in mind that, although rare, occasionally the lamp power supply will fail in such a way that it will take out the lamp and any other lamp that is put in. So if your new lamp is blown, it is likely the lamp power supply that is at fault and you will require a new lamp as well.

Make sure the interlock switch is activated by the cover of the lamp.
Can't measure a voltage with the lamp cover open. High voltage is powering the lamp from an smps or ballast supply. If lamp is New, cover switch is good, then the lamp power supply could be faulty.
