2008 G37 LCD Screen not Turning on Occasionally

[dfresh1988]

Okay so I've searched for answers on this for quite some time but to no avail. I have an 08 G37s with all the option packages. From time to time when I start my car, the main LCD screen does not turn on. The most noticeable times is when it's cold or rainy outside. I keep the car in the garage all the time. My wife and I work together and drive her car to work so I don't put more than 5,000 miles a year on the G37. So here's what happens:

I start my car. Everything starts up and turns on but the LCD screen stays black, no backlight or anything. All sound, fans, A/C etc. still work and are controllable. Here's the kicker: I can tap the screen and whatever button is where I'm tapping still works even though the screen is off. I can turn the car off and back on over and over and it'll just not come on. This is about 60% of the time I start my car. The other 40% it works fine. Usually after driving for about 10 minutes to a half hour (in my mind the car is warmed up at this point) I can turn the car off and when I start it back up the screen usually comes on. It's the strangest thing and very hard to replicate.

I took it to the Infiniti dealer for an oil change last month and asked them to take a look at it (of course this was a day when the screen worked fine, funny how that works out) and all they could say was they could try out a new screen and see if it works better. Oh, and that's $1,100. So I said no thanks I'd deal with it.

Any ideas what this could be?? It seems to me it's entirely functional since the touch features still work it just seems like it has a problem firing up the backlight or something. Anyone had this problem before?

If it's just the screen you can get a replacement on ebay. In fact, the newer models are supposed to be better. Replacement is easy assuming the problem is the screen.

Haven't seen this issue come up before...probably wiring or bad screen. Try to take it apart and reconnect.
