There are detailed instructions in your users manual on how to check and adjust your Topcon laser. You'll need a tripod, 2 vertical surfaces about 50 meters apart and your laser receiver. It's done by marking positions of the beams, on the different surfaces and then adjusting your laser position to the center of the different positions.
The procedure is different for different models, but i have attached some pictures from the manual for the RL-VH4 series.
It could be a few things.
1. Bad keypad / power button ($30.00 and labor)
2. The power connection is lose from the main board.
3. Corrosion on the rear battery terminal.
4. Lose connection / Battery Springs
5. Bad Main Board.
Most of the time when a laser will not power on, it is a battery connection issue. You can carefully open it and inspect the wiring (red and black cable that goes to the green main board)
If the only problem is that it wont power on I'd be willing to bet it's repairable. Those units are notorious for not holding calibration. If you drop one chances are it may no longer hold calibration due to a bad compensator.
Any laser dealer with a service center should be able to pop that thing open and fix it pretty quickly
If you don't want to pay to have it repaired, open it and check the connections. Be careful not to touch anything unless you have an esd wrist strap, or you could damage the main board. At this point it's already broken so there is no harm in trying.
