How to choose a used car
Fooling the projector
yes your right, just 1 wire it takes to make it work. I've seen some diy light, i'm working with dsu reflector, and car headlight bulb. assembly is hard but fun and time consuming. good or bad i'll update you. i hope it work's
congrats! If I understand correctly, you have identified the control wire on the motherboard's side and put the right signal there to make it think that the PSU works correctly, right? As for the DIY light sources - it's clear that today these should be LED-based, but I never built them myself, so I can't give the specs. There are several good instructables on this topic here, though.
i made it work, not bypassing through the cable of ballast but through the motherboard itself. the projector is running, still figuring out what light to use. i sampled it using a flashlight and image is coming out. thank you fo replying i apprecite it. i would love to send pics but its already assembled.
hi, is it a lamp power supply board or something else? The image is quite fuzzy, I don't see what is written. In any case, start with searching for the schematics - you will see clearly what leaves the main board and what kind of return signal it receives from the PSU. If you still don't manage to find it, then make hi-res photos of this module from both sides and put here.
Good day, can you help me fool my projector thinking it have a bulb. its a canon lv x6 with a ballast of ushio. what wire and where to attach pls detailed it. i just starting doing this electronics thing and still learning. i will put different light source with different power source.
the two on the right side are the same, one at the left is upside down.
did you play with wires coming to the lamp itself? If yes then it shouldn't have helped - the power supply won't send the "OK" signal to the main board since it runs all the "ignition" tests. How many wires connect the lamp's power supply with the main board?I don't know this particular model, but I would say that there should be ground, +VCC, one signal wire to the PSU and one signal wire from the PSU = at least four. I hope it doesn't use some sort of serial bus since emulating the protocol is out of the question in our case. Can you take a picture of the lamp's PSU from both sides of the board and send it?(I would also search for the circuit diagram for this very model)
Help me brother... please.I have lg bs275 model dlp projector.I dont have much money for buy new and original lamp.So i think use high beam diy led and drivers.I want to bypass bulb check circuit.I tried many times....but failed...I shorted that two wires from reverse opto couplers....didn't work.I grounded each wires...again failed...It have keeps red indicator after blinking green. It displays lg logo for 3 seconds when i put external light source. After it shows blank screen.I dont know what to do.Really i want to make it work.Pls pls pls help me...Sorry for my bad english.I hope you can help me
start with searching for the circuit diagram - then it'll be clearer which wires come to the lamp and how the protection is organized. At the first glance I would say that one has still track the wires from the lamp's power supply unit to the mainboard. In any case, you'll remove the PSU since you don't want to have high voltages without load in your projector.
Hai....i have lg bs275 model dlp projector.Lamp got damaged. I want to do bypass it's bulb check circuit.It have 5 wires from octoplersI am confused that which wire should i connect...Pls help me
