    PCB needs repairs

    Hi Kris, I really appreciate any help I can get with this. Christmas is coming up and my wife wants this piece of equipment OUT (!!!) of the house! The good thing is, I have a working pcb for comparison so this helps a lot. What you think is a fan connector is actually a connector for DMX...

    PCB needs repairs

    Hi QC, I swapped out the caps and the problem still exists so the problem is somewhere else on the pcb. Any ideas?

    It's broke...

    Hi Clueless, I read this over a couple times and I've dealt with similar problems with fog machines a lot. If you're getting continuity on the heating element it's probably fine. It's probably a thermal fuse (under the red rubber insulation) on one of the lines sending 110V to the heating...

    PCB needs repairs

    Hi QC, I replaced the relay already with the one from the working pcb so it has to be another component. You said you're not surprised about the caps as they are 35V. Can you explain? Also, should I change out the caps?

    PCB needs repairs

    Hi QC, here's the update. I took the working pcb out of the unit and benched it side by side with the non-functional pcb. Here's all the readings I gathered. On the working pcb I'm getting the 18V and 5V at the 7805 as you said (that's why it works!!) and I'm getting 18V and another 18V on the...

    PCB needs repairs

    Following up further with my learning process here, the capacitors (both 35V 200uf) handle the input and output from the 7805? One handles 18V going in (before the 7805?) and the other 5V coming out (after the 7805?) I was wondering, what's the purpose of these polarized capacitors? Are they...

    PCB needs repairs

    Hi QC, I fully understand it's a working experience for me but I have learned from experience that experience gained from actual practical repairs is better than anything read from a tutorial but both are necessary. So, the bridge rectifier (what I referred to before as an AC/DC converter)...

    PCB needs repairs

    Hi QC, a schematic is impossible as it's an old unit and the company won't be of any help with this. The big IC drives the two transistor arrays, which I am sure are the motor drivers for the color, shutter and iris motors. I swapped out the large IC, the transistor arrays and the 555 before...

    PCB not functioning

    Hi QC, I might get my hands on an old isolating transformer from a client, probably over the course of this weekend so if I do, I can start testing. I was wondering if you could advise me on another pcb? I posted before on these other pcb's, I got a little assistance but I haven't gotten any...

    PCB not functioning

    Hi QC, I did the necessary research on the isolating transformer and I fully understand it's necessity for this type of repair. However......I checked around at quite a few electrical suppliers for this type of transformer and the majority are clueless as to what I'm asking for. However, one...

    PCB not functioning

    OK QC. FULLY UNDERSTOOD!!! DO NOT FOOL AROUND WITH THIS UNLESS I AM THOROUGHLY AWARE OF ALL THE DANGERS INVOLVED!!!! Got it. How do I proceed from here? First of all, I can secure the PCB firmly to an insulated surface, probably a piece of plywood lined with a piece of electrical insulation...

    PCB not functioning

    Hi QC, I attached two schematics before. Did you check both to see if they are what you need?

    PCB not functioning

    Hi QC, the private messaging does not have the option to attach the .pdf. What's the best option here? Please bear with me, I'm new to all this.

    PCB not functioning

    Hi QC, the LED's do not light at all on one pcb and the green LED lights and dims on the other on startup. As I mentioned before, these PCB's are for strobe lights and the socket for the lamp is in the center of the pcb. When the PCB's function perfectly, the green LED lights constantly and...

    I am also not too excited about getting shocked again so any help will be greatly appreciated.

    PCB not functioning

    These boards are for strobe lights. I removed them for repairs as the lights were no longer functioning. When they are working, there are 2 LED's, one green, signalling power, and one red, that flashes when the lamp flashes. The quality of the schematics is terrible because I had to reduce the...

    LED constant current driver 80 Watt?

    Hi Coca Cola, Will any of these help? http://www.acclaimlighting.com/products/catergory/category/drivers-1.html I also think I have 12V and 24V 150W power supplies in stock. Maybe these will work. Let me know.

    PCB not functioning

    Hi, I have a couple of these PCB's in need of repairs. They work with very high voltage, up to 500 volts, and I've gotten a very lively shock from one of them already when I tried to troubleshoot so I would love to get some advice from the wise ones in the forum before I electrocute myself. The...

    PCB needs repairs

    Hello everyone, This PCB runs on 12V AC in from a transformer and the is an AC/DC converter to 18V DC and it has three motors that control a shutter, an iris and a color wheel (the terminals for these motors on on the right of the image). I repaired a similar PCB before which had a faulty...
