Replaced Nav Screen 06 Is250....at Wits End!

[Mksayavan]

I recently purchased a 2006 is250 3 weeks ago. The day I bought it the screen started going off and then flickering back on. When it's on, the touch screen and all the buttons around it work. When it's off the climate control will stay on whatever it was on when the screen went off., but all the buttons go off as well.

After lots of googling I thought it must be the screen getting ready to permanently go out.

A couple hundred dollars later here I am with a new screen and the EXACT same problems.

Just had the screen replaced today and I don't know what to do next. Some observations...all touchscreen options work when screen is on, it seems to come on more when it's hot outside, it stays on less than a minute when it does come on...

ANY HELP WOULD BE GREATLY APPRECIATED!!!!

it could be bad power supply for the screen or a short in power wires for screen very rare. what is common is that the 4 small power wires to lcd screen it self have been pulled loose. the internal power supply wiring goes to screen through a small 4 pin connector to the screen which is easily broken if pulled on. that connector has to be gently removed with small screw driver prying it off by on the 2 sides of connector. it if not the wires pull loose if pulled on which would be giving an off on effect. so my diagnosis is that the lcd screen was replaced previously because of common touch screen not working. in process of replacing the screen the power wires were pulled loose and difficult to install back into connector tightly. I can sell and send a working screen assembly for 700.00 and will send 350.00 back after you return the broken unit. 99 % I can repair the broken unit you send back. . I have replaced dozens of screens and pulled the power wires out the first time myself so quite aware of pitfalls. . also the replacement unit I will send has a 2009 lcd screen in it with touch screen defective solder removed. i am sure the screen you had replaced is just another 2006 7 8 lcd screen which will fail again as far is the touchscreen touch not working. problem

Pioneersuby are you talking about the ribbon connector from the circuit board to the screen? Where is the power supply? Is it part of the screen? The screen I just had replaced is brand new and still has the plastic on it, so this may be a dumb question but aside from the likeliness it will go out again why would I need to replace the screen again? Thanks,
