REC Navigation Radio Blank Screen Repaired

This past winter the screen on my REC radio would go blank after a bit of driving and when this happened, the bottom and right side buttons no longer worked. I could change the radio station with the preset buttons and adjust the volume with the steering wheel control, but that was about it. Fast forward to now and the radio display never comes on anymore and I wanted to fix it. I found a replacement radio to swao in for $200 but found that the Navigation system would not load the disk on this one. So I decided to try and make a good radio out of two bad radios and find out what caused the blank screen problem that seems to be rather common.

If you are going to try this, I recommend that you get a good quality small phillips screwdriver since it will be used on every screw that you have to remove.

What I found: The control board for the navigation CD drive was causing the blank screen problem. Swapping this board with another one fixed my radio.

Start by removing the three knobs on the front. After you remove the 12 screws around the perimeter of the front face you just need to pry on the corners a bit to pop it off.

Just a few more steps and lots of little screws.

I have no idea what is wrong with the nav CD board, but swapping in the board from the other radio solved my problem. To re-assemble, just reverse the steps and avoid the pitfalls that I noted.

Great write up, and thank you for putting this together! My REC screen is finally going all-blank so will be pulling everything apart very soon to take a look. I'm hoping it's just a problem with the ribbon connector, but if not, I should be armed for the task. Much appreciated

Do you happen to know the make and model of that control board. I'm looking to see if it can still be purchased without having spend the big money a new or gently used replacement REC system.

After talking to the tech at Factory Radio Parts we determined it's the control board. The black one above the dvd reader. - They don't have any.

So, I 'reflowed' it. It works!!!

I followed the directions from http://www.computerrepairtips.net/ho...p-motherboard/ especially the comment from a guy who does it professionally.

I have a 2 hour drive coming up to really test it out.

OP, great write up on taking it apart, thank you. I can't find any decent cheap replacements for the nav board so going to try the reflow method.

Wookiee, which side did you place up? and what temperature did you use for how long?

DO NOT USE YOUR HOUSEHOLD OVEN FOR REFLOWING.

If you wish to reflow properly, you need a reflow oven. You can make one, or find someone who has one. https://www.whizoo.com/ - or you might even be able to get away with just a toaster oven, if you don't care about heat curves and actual temperatures. But that toaster oven should NEVER see food again.

Please do not do this in the same oven humans cook food in.

You would be better off taking a jewelers loupe and looking at the connections to determine if you are dealing with tin whiskers or a broken solder joint somewhere on that board. Then just reflow that with a soldering iron. Likely not tin whiskers if you can reflow at tin/lead temps.

What's wrong with using household oven?

I just did mine about a hour ago, in my household oven lol. I had this issue but wasn't due to the heat component failure, it just gave up totally so had to have been a faulty solder joint. Preheat oven to 390, put board on foil sheet on baking pan, wrapped all plastic parts, antenna, and bigger components, popped it in with door closed for 10 seconds, shut oven, opened door, and let cool. Put radio back together and it worked like a charm.
