seangreer Posted November 6, 2012 Share Posted November 6, 2012 I had two HC300 units fail in the field in different locations and Control4 wanted $220 each plus shipping to repair them. Nothing against the repair department, but that is way out of line pricing. For the DIY crew, the part number for the power supply board is PSA15LN3-050-R and can be had from Mouser for $19. There is a total of 4 screws inside and 8 outside to get to the board. The repair takes less than 10 minutes. At any electronic store, this is under $125 even with a markup and a minimum charge. I'm looking at $45 / unit with time and shipping accounted for. AnOutsider and tratliff 2 Quote Link to comment Share on other sites More sharing options...
HeliNut Posted November 7, 2012 Share Posted November 7, 2012 You are way undervaluing your time, for starters.For any reasonable sized operation, you have an employee to pay, healthcare, 401K, payroll taxes, the 100 sq ft of work area, desk, handtools, training, 10 paid holidays, vacation and sick time, not to mention factors of employee efficiency.Then you have your power supply, inventory carrying cost, and some reasonable markup of maybe 30 to 50% on parts.Finally, there is some level of warranty on the work (I am guessing here), which probably has some value in an actuarial table somewhere.And you want that for $45?Personally, I would be happy that I could get the product serviced at all, being that we live in this disposable society.But hey, if you want to do it yourself, more power to you!

andy.cytexone Posted November 7, 2012 Share Posted November 7, 2012 I like it, Sean - thanks for posting... it's better than stocking spare HC-300's Quote Link to comment Share on other sites More sharing options...
RyanE Posted November 7, 2012 Share Posted November 7, 2012 If anyone wants to do this, just be aware that inside the HC300 you should observe proper anti-static handling during repair.RyanE Quote Link to comment Share on other sites More sharing options...

gem Posted May 26, 2013 Share Posted May 26, 2013 Hi, I purchased a replacement power supply and have removed all the screws on the back of the case, but still cannot remove it. Which screws hold the case in place? Quote Link to comment Share on other sites More sharing options...
RyanE Posted May 27, 2013 Share Posted May 27, 2013 Under the 'feet', you remove the rubber pads, and remove the screws under the plastic foot standoffs.I think screws on the back are not used at all to hold the case on.Good luck with your project.RyanE Quote Link to comment Share on other sites More sharing options...
gem Posted May 27, 2013 Share Posted May 27, 2013 Thanks. Got it and replaced the power supply. Once I found the right screws, the rest was pretty easy. HC300 is now working, again. Given that this particular box serves as the ZAP coordinator, I figure I just saved myself about $2,000 for a new HC250 and all the associated dealer reprogramming of the mesh.

Bob52 Posted November 4, 2013 Share Posted November 4, 2013 The power board on my HC 300 failed, and I have taken it apart. The part # for the board at Mouser is made by Phihong, while the one in my Control 4 was made by Dongah Elecomm. Can I replace the Dongah Elecomm with the power board from Phihong? Thank you, in advance, for your help. Quote Link to comment Share on other sites More sharing options...
THEORY Posted November 4, 2013 Share Posted November 4, 2013 If your Dongah isn't working it sounds like it's time for Phihong tratliff 1 Quote Link to comment Share on other sites More sharing options...

WFNC Posted October 4, 2015 Share Posted October 4, 2015 FWIW - my failure rate on the OEM Dohgah power supply has been 100% within 5 years. OK so it's a small sample set - two of two units. Both have been replaced with the Phihong supply and now one of those has failed within a year. Both HC300s are on substantial surge protectors with battery back-ups. I think the problem is that both supplies are the bottom of the barrel of the lowest form of made in China crap. Unfortunately no one makes this class of power supply outside of China, but I'm replacing this time with a TDK-Lambda unit. Hopefully it lasts longer than a year or two. And hopefully Control4 has upgraded this weak link in newer hardware. Quote Link to comment Share on other sites More sharing options...
hike Posted December 12, 2015 Share Posted December 12, 2015 My HC-300 power supply went on fritz. I located a power supply but I need the cable! I can't find one quite like it online. Its a 4 pin female connector with 2 wires on one end and a 2 pin female connector with 2 wires on the other. Anyone have a spare from an old unit?

C4Blimp Posted December 13, 2015 Share Posted December 13, 2015 I have never had a 300 fail. And hopefully Control4 has upgraded this weak link in newer hardware.What!? I needed a good Sat. afternoon laugh. Control4 has no more of a problem with 300 PSs than, say, Netgear has with their switches and WAPs.

zaphod Posted October 23, 2016 Share Posted October 23, 2016 I bought an HC-300 on eBay(I got a refund) that is dead but I may try replacing the power supply as that may be the issue. Can I temporarily just use the 5V line from a PC power supply just to ensure that the PS is the problem? And it looks like Mouser no longer carries the Phihong PS.

zaphod Posted October 24, 2016 Share Posted October 24, 2016 I have taken the HC-300 apart and two of the larger capacitor that are close to the DC connector have bulges so I guess this could mean capacitor plague. The PS is made by Dongah and has a date of 2008-08-30. And to answer my own question, yes, you can just wire it up to the 5V line of a PC power supply. I did that and the controller came to life. Next step is to buy a power supply. Mouser doesn't have them but Allied does. Quote Link to comment Share on other sites More sharing options...
zaphod Posted January 28, 2018 Share Posted January 28, 2018 Maybe call Allied - the part is still on their system they just have 0 in stock. You could also try buying a used HC-300 on ebay as they seem to be going for <$50. That's not much more than a PS, but then the PS in that unit may not last long either. As is alluded to above - I temporarily wired one up to the hard drive power leads from a PC power supply. If you know your way around a voltmeter you might want to give this a try. There's nothing special here you just need a 5VDC power supply that can output 3A. Quote Link to comment Share on other sites More sharing options...
zaphod Posted January 30, 2018 Share Posted January 30, 2018 That's about $10 less than a power supply. And as long as you are happy staying on the older OS then you can buy one for every room in the house if you can keep finding them at that price!

zaphod Posted January 30, 2018 Share Posted January 30, 2018 Where are you located? I took a quick look and it doesn't look like any of those have the same connectors. So you may have to rewire a connector to get those to work. And some of those are not the same size either so it might be tricky to screw them down to the case. You might want to keep buying used HC-300s for cheap prices. Quote Link to comment Share on other sites More sharing options...
hunger Posted February 24, 2019 Share Posted February 24, 2019 My HC300's power supply has given up the ghost as well. I'll just buy an HC300 on eBay and cannibalize its power supply. Quote Link to comment Share on other sites More sharing options...
Sefiro Posted May 28, 2021 Share Posted May 28, 2021 Late to the discussion but posting for future diy's. Client wanted to repair rather than purchase new equipment. Just wired in a COSEL LFA15F-5v purchased from Mouser. I also ordered the matching pigtails from Mouser. (Cosel website will tell you which pigtail needed). Had to be creative for the case mount as the PS footprint is different. Quote Link to comment Share on other sites More sharing options...
zaphod Posted May 28, 2021 Share Posted May 28, 2021 Apparently some of those power supplies are getting harder to find. Another idea is to buy used HC300s on ebay and use them to harvest power supplies - but who knows how long those may last either. Quote Link to comment Share on other sites More sharing options...
RyanE Posted May 28, 2021 Share Posted May 28, 2021 Kind of surprised no one has just tried to repair the P/S. I'm sure it's likely to be bad caps and/or the regulator IC itself. RyanE Quote Link to comment Share on other sites More sharing options...
