This Sony VPL-HE45ES projector was dropped off by a home theater service company in the area. The customer lost both HDMI ports without explanation. After verify the issue and upgrading the firmware as a last resort, it was decided to replace the mainboard.

Replaced the stepper motors in this GM gauge cluster. I forget what model truck its out of. Either a Tahoe or Suburban. The truck has been sitting for a year because the speedo finally stopped moving after the RPM and temp stopped. I replaced them all with a kit I got on Amazon and then I adapter some 5050 Blue LEDs to fit in place of the backlight bulbs. The LED uses a 150ohm resistor for current limiting. my phone was recording in 1080 not 4K Motor Kit www.goo.gl/eTFoq7 ... https://www.youtube.com/watch?v=z1q4VZmR8tI

Here is my test rig I use for making the sure the IR cut coating on projector lamps is good enough. Technically these should also be blocking UV but I have no way to test that at the moment. If that changes I will make a video. The coating is also called a cold filter. It prevents the IR from heating up the optics anymore than they already are by blocking the radiation from leaving the lamp housing. This is a big part of why proper cooling is so important. My understanding is that it is mostly used in DLP projector lamps. LCD projectors (and some DLP) have the filter in another location of the projector. This should not be a concern for LCD projector lamps, only DLP lamps. A good rule is to make sure the filter looks like the filter in your old lamp. Even if your old lamp exploded, the filter will be obvious enough to compare. Save your old lamp until you install and use the new lamp. Depending where you purchase it, having the old lamp around for parts can be quite useful. Many lamps are not sold with the proper filter installed. The 'greenish' filter will sometimes work for a little while but they are far from reliable. The most common symptom of too much IR is your color wheel will start to flicker when the lamp reaches full brightness and the whole projector will shut down. Here is the lamp in this video. These all have good IR filters.https://www.purelandsupply.com/optoma-projector-lamp_bl-fu195a.html If you found this interesting please let me know.
