I've been looking for anyone who has had a similar navigation problem, but haven't found one. Hopefully someone can give me a possible solution or help to determine if my problem is linked to the already known 'frozen screen' issue.

I have an '06 IS350 in Breakwater Blue, bought it brand-new in Oct. '05, currently has 140k mi.

My screen died on me about 6 months ago. When I say 'died' I mean no signs of life at all & it's essentially BLACK. Nav screen has no illumination. Now the radio & cd changer DO work, so I have music & the clock only. Side buttons surrounding the screen; (a/c, menu, audio etc.) have no illumination & are not operable either...... HOWEVER, approximately every 6 weeks or so, the screen will flicker a few times, I will see lines & the screen will begin to fade back in & the entire unit WILL become totally operational for just about 10 minutes (this is the only time I can get to make my a/c adjustments which will stay in effect for about another 6 weeks because it will die shortly thereafter.)

Has anyone else had this issue? I see the the more common complaint & problem is having the screen "Freeze" & totally locking up on the home screen. But my screen seems to have a short or power interruption.. Is it possible to fix my blackout with the same DYI for frozen screens, or is it something different? Of course the dealer wants $2300 for a new unit, but honestly.. I simply cant afford that, otherwise it would have been fixed months ago. Another possibility I thought was if this could be fixed by just replacing the 7" screen. What do you guys think? Any help would be tremendously appreciated!!!!!!!!!

 

Have you thought about an aftermarket unit? Unless you are good with electronics and will tear into the NAV unit yourself testing everything with a multimeter, I think an aftermarket unit would be your best bet.
