However, burn-in remains a potential problem with large-screen video displays such as those found in home theater systems. Newer computer displays rarely exhibit burn-in except under extreme conditions. In older cathode-ray-tube ( CRT) displays, screen savers were used to prevent burn-in. This problem is also known as screen burn or phosphor burn. The term burn-in is sometimes used in reference to a phenomenon in which faint, permanent "ghosts" appear on video displays that have displayed fixed images for long periods of time.
The equipment is powered-up and then left to run continuously for hours (or sometimes for days) until the malfunction is observed and can be diagnosed. Under these circumstances, a burn-in must be performed and environmental parameters varied until the problem is found. When a faulty device or system is brought into a repair facility, the malfunction might not occur until the hardware has been warmed or cooled to a certain temperature. If any of the components are defective the problem will usually show up within this initial testing time frame. Burn-in is a test in which a system or component is made to run for an extended period of time to detect problems.īurn-in may be conducted to ensure that a device or system functions properly before it leaves the manufacturing plant or may be part of a repair or maintenance routine.Īn end user may use a burn-in process to ensure that new equipment is functioning properly, for example, running a new computer for several days before committing it to serious use.
