If you have a Hanns-G HC194D with a flashing power light or not power at all then this should get you back going again. The problem with this series of monitor is 5 failing capacitors on the power supply board. To do the repair you will need the following tools: Soldering iron, de-solder braid, Phillips screwdriver, small flat blade screwdriver and a 3/16″ nut driver. You will also need the following electronic parts: qty(2) 220uf 25v capacitor, qty(2) 1000uf 10v capacitor, qty(2) 100uf 50v, qty(1)47uf 50v, qty(1) 4.7uf 50v ,qty(1) 100uf 25v and qty(2)470uf 25v. We sell a repair kit with all of the parts for $14.00


This is not guaranteed to solve all problems but in most cases this is the issue with this model.

If you don’t want to do the repair yourself, use the service request link above. Most monitor repairs run $30-35 plus return shipping.

Here is the power supply board with the faulty capacitors labeled:

A and B: 10v, 1000mf
C and D: 25v, 470mf
E and F: 25v, 220mf

After replacing the capacitors reassembly the unit and you should be back in business.

    I can add to list of capacitors to replace another one, a small one of 25v, 220mf that can be seen in the lower left of the photo and above the metal plate.

  12. Disassembly to get TO the power supply board is a little scary. But I did it, soldered in the caps, and reassembled in about an hour and a half. And the monitor now works like a champ again! But if you are at all uncertain about your skills in getting the shell open (requires prying that can/will/did leave marks that I don’t care about) and successfully unplugging the five rather fragile connectors without breaking any wires..(I broke two and had to repair)….then consider using the site’s extremely reasonable repair service (which was looking pretty good to me — too late — when I broke two tiny wires to one of the connectors). But it CAN be done and it works!!

  14. Excellent to find a site that pinpoints the reason for the fault and supplies the components.

  18. I have had this monitor since early 2006. First time ever that I have outlived a monitor. I am really surprised it died before I got a new one, but since it is a very nice monitor, I am glad this service can repair it, or provide the gear to let me repair it. And at an excellent price too, cuz most sites are charging the same as the cost of the tech kit and cap kit, but you only get the caps!

  20. will this kit work on the HG216D model?

  21. CCL_TECH on Fri, 22nd Feb 2013 2:04 pm
  22. Hello,

    There are two different power supply boards that were used in the HG216D monitors. Do you know which board you have in the unit? We can get you the correct parts but we need the board information. You can either post a picture of the board or post the part number from the board and we will get back to you.
