How do you reset lamp timer

I have a Panasonic PT-AE4000U and could not reset the timer after replacing the bulb with a, non-Panasonic branded bulb. Calls to tech support were not very helpful. It was another bad customer service experience. Through troubleshooting it myself, I discovered the solution was simply to unplug EVERYTHING (serial cable, hdmi cables, etc.) from the device, power it off and back on. Follow the procedure in the manual, the timer immediately reset!!

Have reset the lamp hours after installing the new lamp? If, not the projector has treated the new lamp as old lamp & refusing to light further. So, reset the lamp hours to zero. To reset the lamp timer do as follows. Plug the power cord into the AC socket of the projector. Switch ON the power of the socket. (not projector) While pressing simultaneously INPUT, ENTER & UNDO on the projector, press ON on the projector. "LAMP 100%" is displayed, indicating that the lamp timer is reset.
If this does not correct your problem then the problem lies in other area. Let me know so that further I can provide you solution. Above things are preliminary

Press RESET, <, >, ENTER keys on remote within 5 seconds to reset lamp timer.

Honestly I would try entering the 'Lamp timer reset' code again. Or the button sequence given to reset the lamp timer.
An issue that may be happening is that something may have happened to the lamp ballast power supply also.
Just a thought.

You have to replace Lamp before resetting Lamp Timer and most of all the ones I have replace TV does it Automatically.But if you do have a problem on Menu go to Lamp Timer and reset.

OK, that explains it. The bulb you have installed in the projector might be the original bulb that came with the projecoter when it was new. Just becuase it states 334 hours does not mean it is new. In fact, you could have a original bulb with 3000 hrs and reset the hour timer on the projector, which means your 3000 hour bulb might have 3334 hours on it because the person who owned it before you, reset the hour timer.. Best bet, buy a new bulb and reset the hour meter and see what happens. If you have the same problem, then your ballest might needs to be replace which is rare...

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.
