The only part of the installation that is tricky is picking up the rig’s dimmer circuit.

The PDF instructions are in full color with step by step disassembly instructions and then step by step instructions to install the LED mod. This board is pre-assembled and the output voltage is set by Max.
The other board is a DC to DC converter taking a regulator and outputting 13.5VDC so the display does not flicker from any voltage drop during transmission. That board has about 10 parts and is well silk screened so assembly was very easy saving a few dollars.

The kit that I bought did not have the LED driver board assembled. Overall I would say that a week from Canada through customs was a tremendous service.

I decided to do the mod and paid for the kit via PayPal and received the kit a week later in a box that had layer upon layer of bubble wrap to protect the contents. Almost immediately he sent me the PDF instructions so I could make up my own mind whether or not I would do the mod. I emailed Max Donaghue (VE3TMT) and had some questions about the kit’s installation. So I did some research and found VE3TMT’s LED mod to cure the low display intensity on the ProIII. The display did not get any brighter from 65% on the menu to 100%. So The rig I purchased had to be at least approaching 10 years old and probably older. The last production run of the ProIII was, from what I understand, January of 2009. The only problem was the CCFL back light did not bring the display to a reasonable intensity. I guess we can thank Icom for the price reduction on the SDR 7300 that ultimately dropped the price of good used rigs. I had been looking at it for many years and finally found one that was extremely clean inside and out for a very reasonable price. So I finally got my dream rig of a Icom Ic-756ProIII. Even at 0% brightness the display is brighter now than with the CFL. I can now set my brightness and contrast to 50%, down for 100% prior.

Overall I am very happy with this upgrade kit and the display on my radio looks like it's brand new. The only way Max can make it easier is if he does it himself (which he does offer for an additional fee) If you can solder well and have about 2 1/2 to 3 hours of time then you can install this kit. To my surprise he called me no more than 3 minutes after I sent the e-mail and we talked about some of the places that he knows that ground clips went. When I opened the front of the radio up there was a ground clip laying in the plastic, since Max has worked on a lot of these radios I e-mailed him to see if he knew where it went. One thing I would recommend is to order some 30 awg solid wire, this will allow you to put the wire inside the dimmer via instead of soldering to the top of the via, which has a neighboring via very close by. The hardest part is getting the diffuser lined up just right to go on the display. The instructions that are sent are great and walk you through every step. I ordered the kit and about a week later it arrived, which is pretty quick for a international package from Ontario to Wisconsin.
I e-mailed Max to ask a few questions and surprisingly he sent me the install instructions and let me look them over, this helped make me decide that this was a project that I could take on myself. My IC-756ProII started to have a dim display recently so I looked into this issue and came across the VE3TMT conversion kit to change it from CFL to LED.
