The Pro Cinema LS12000 is a premium home-theater laser projector where long-term value depends on optical performance and stable electronics. Laser light sources are rated in hours, and real "lifespan" is heavily influenced by ventilation, dust control, and usage patterns.
If the issue is a replaceable board (HDMI, power supply) or a fan/cooling service under the threshold, repair is often worthwhile because the projector's core imaging and install work (mounting, calibration) are expensive to redo. Replacement becomes more rational if the optical block is compromised (persistent blotches, severe dust intrusion, uniformity problems) or if repeated overheating/shutdowns suggest deeper engine problems.
Also factor in warranties and service logistics; shipping and downtime can materially change the decision.
