Most high-end projectors, such as Barco projectors are fitted with fans, colour wheels, filters, and lamps that are programmed to run for a certain number of times called TBO or TBOH ‘Time between overhauls’ as in airplanes.
When the counters record the number of cycles as programmed, the machine may no longer boot, or it may boot with error code such as ‘Low Frequency Maintenance Error’
Blinking Red Light. Blinking lamp or temp Light
Epson projectors are famous for the 3 red blinking light, this is often preceded by fan overdrives. For JVC D-ILA projectors. It is 6 red or amber lights, depending on models. Sony projectors, Mitsubishi, etc all have these indicators.

Burnt Patches, large Static Stains on Projector Image
This is a common issue with LCD and DLP projectors. For DPL projectors, It could be as a result of burnt aspherical plastic lens. This aspherical plastic lens is deep inside the lens assembly. Burnt to the aspherical plastic lens cannot be cleaned. Replacement is imperative.
Infrared (IR) filters in integrated dichroic glass in the optical assembly are meant to filter out heat from the lamp from reaching the more delicate optical elements along the light path.
Dust and Dark Spots on Projector Image
Projector lens assembly are sealed. However, very fine dust particles do find their way inside the lens cavity. Alternating heat and cooling events excite these particles and cause them to bond into irregular shapes that grow over time and becomes visible on images. Regular maintenance is the only preventative measure that is effective against this phenomenon.
Yellow, Red, Green, Purple Hue on Projector Display
LED light source produces higher brightness to conventional UHP lamps, longer lifetime, lower power consumption, and lower total cost of ownership (TCO), However, for the same power input, laser diode light engine gives brighter display because the laser diode light beam are more focused as opposed to that of LED light that is more scattered.
Dull and Dim Projector Display
When the images projected by a projector becomes dull or dimmed. The first question is what type of projector it is. DLP, LCD, LED, LCoS, Laser or SXRD powered projector.
If DMD, areas of attention would firs the least difficult to access component; the lamp. Ensure that the bulb is clean and free of dust. If new lamp is installed and the dullness persist, likelihood of failing DMD chip is high.
No Inputs Recognized by Projector
Projector nowadays are equipped with a range of input ports; VGA, DVI-D, HDMI, USB, RCA, Optical port and Component Video, Composite Video and S-Video, RS-322 port, 12V Trigger, and Network.
