Toyota Avensis T25 Not working multy display

[todorst82]

Hi guys, I had problem with Avensis 2005 display. It doesnt work at all, blank, no light, no symbols. I try to find solution here but I didnt find anything. Made more research and find some russian sites with info. I already fixed it - so the problem is in one SMD resistor of "0 Om". You have to exchanged it. As I undestand this resistor its like fuse, but let someone with more knowledge to explain how it is works. Ive made some pictures. I hope that will help some Toyota owners!

Thank you. I also solved it in the same way.

Excellent

Hello, I have a Display that all the shunt or (0Ohms) resistors are fine. I have marked them with a green oval in the photo. Then, with blue oval, coils that appear 5V. There is one, with a Red oval, that raises the tension a little, and then falls. That tension feeds the screen. Any idea where to look? Thank you!. If you need any measurements, ask me and I'll post it.

Hi
Check the capacitors next to the zero ohm resistor. They seem dodgy

​Good morning!. I have changed all the electrolytic capacitors, and it is still the same. There are no shorts on the lines, and the resistors, on each line, are correct (I have one motherboard that works and two that don't). I'm suspecting some transistors...

I was referring to the small tantallum capacitors

[joaquinmjuan]

They are fine, although I have no way of knowing the value, but there are no short circuits in the positive of the capacitors. In fact, a plate came on for a moment. He thought it was cold welding, but no, because I've gone over everything. This afternoon, I pick up another working board, and I will continue investigating... but it looks like it may be a transistor, since there are still voltages to activate, which depend on some transistors.

Hi, i have the same display, the symbols are fine works perfectly but only the backlight doesn't work. What could be the issue?

[joaquinmjuan]

If you remove the screen, it has two LEDs or two Lamps...I couldn't tell you, because that hasn't happened to me. Check that they are good, and check the resistors that have to do with the contacts of said LEDs or lamps.... it may be that some resistor has a bad solder, or some that says 0, is damaged. To do this, you have to use a soldering iron and a multimeter.
