Tns310 Ctr Display Frozen And Does Not Switch Off !

Recommended Posts

Hello,

I have a 2006 avensis T25 with the small monochrome center display (milage and navigation) but i have the problem that the display is frozen and when i shut down the engine the display stays on,the buttons unther the display does also not work.

Do i have to reset the system (and how) or does someone knows how to fix it?

Thanks,

Günther

Hello mate ,

this MAY help you (sorry not got time to search the whole thing today), it's a .pdf of the audio/visual system.

Best regards,

Pete.

Can you tell us on here exactly how you did it so it will always be searchable on the forum in the future.

Thanks

Pete.

Yes, I think in the forum should be unwritten rule- when somebody has a problem, after fixing it, to give " feedback " here how the problem been resolved.

Hello,

Sorry for the late reply but it was very busy here with the kids,you have to remove the cover from the part where the connectors are fitted and there you will see the pcb,there is a micro-controller on the board (black square part with label 784936agf148) and between that and the x-tall there you will see a smd resistor with a "O" printed on the top,this was broken.if you measure this with a ohm-meter it should be O ohm otherwise it is broken and needs to be replaced (you can just solder a wire over this like I did).

I plugged everything back and it worked.

I made a picture but how can I upload it here?

Happy New-Year !!!

I uploaded the pictures,one picture is with the broken smd and the other with the connectors of the unit because I could not find any info about these connectors (the unit in the avensis manual is with other type of connectors).

Best regards,

Günther

Thanks Gunther, that's very good information, how did trace it to that surface mounted resistor, was it burnt out?

Just by measuring the components,and this smd with "O" was the first one.

The resistor was not burned,there is no visual damage.

worked for me as well perfectly (although the mechanic was sure this cannot be the reason, I still asked him to check.. and surprise, surprise :) ), thanks Günther!

Hi - I have this exact same problem.  How did you remove the display unit so that you could undertake the repair to the resistor?

Cheers,

Roy
