At TeKSwamp we have more than 10 years of positive experience specializing in refurbishing electronics! To maintain the highest standards of service to our customers we pledge ALL of the following. Information below is for educational purposes only. The following information should be viewed as constructive advice based on years of experience. Projector Image Quality, Image Brightness, Thoroughness of Inspections, Proper Product Representation. There are many factors that may affect image quality, brightness and overall value of a projector, most of which goes unnoticed by the untrained eye. Dust Optic Burns Image Quality. Optic burns may discolor the image or create discolored spots. These spots can be caused by the long hours of use, inappropriate temperature or dust. Dust accumulation is present in most used projectors. It tends to create darker projection image and can leave spots on the projection by getting attached to the optic inside. It may be nearly impossible to remove the dust from the optic without completely disassembling the projector first. It can also attach itself to heat sensitive areas of the projector, causing it to overheat or malfunction. TeKswamp technicians check the quality of the projection image and thoroughly clean the inside and outside of the projectors to eliminate as much dust as possible. Important Information about Projector Lamps. Many non-authentic, non-OEM lamps can stop functioning within 6 to 12 months whether the projector has been used or not. Generic lamps may produce a darker or brighter image than an OEM lamp. Non-authentic lamps die more quickly because of inferior build quality, when the gas sealed within the lamp begins to leak. Also, the lamp can be brighter than specified and may burn the projectors optic by running on a higher temperature than the projector is designed for. TeKswamp ensures that you receive a lamp with low hours. In addition, TeKswamp inspects every lamp to check for burns, dust and clarity of the lamp reflector. Projector Inspections and Testing. Used projectors MUST be thoroughly inspected and tested for optimal functionality and endurance. For example, some used projectors can overheat and simply turn off to prevent any further damage. Also, it is hard to notice smaller malfunctions until it is too late, such as malfunctioning legs/buttons or high lamp hours, etc. Example: If a projector leg doesnt function properly, it could create some major hassle if you need to constantly set up, jimmy and move your projector around. TeKswamp inspects EVERY aspect of the projectors it sells. Why do we go through so much hassle?
