No nothing.Did you find something that can be replaced,or behind that LCD is a small electronic board.Maybe there is a malfunction,somethin broken or burned?

The small LCD (which is actually a vacuum fluorescent display) for the clock and odometer is a separate assembly, so that could be replaced as it may be the bad part. There are three separate circuit boards - The large main on, the one that the speedometer display is mounted to, and the "Core" board, which snaps to the back of the large board. The Core board contains the primary processor for the cluster and it has the EEPROM where the odometer data is stored. Unfortunately you can't buy the boards separately from Toyota, but if you can track down one from a wrecked Yaris, which has a cluster with the same part number, then you can either swap the clock/odometer display onto yours or you can swap your core onto it.

Yeah,but used clusters cost over 100$ on ebay,so it is a bit expensive.My dad is a electrician,so i wil disassemble the cluster and give him.Maybe he can find the problem.Anyway thank you for your response,i will notify you if i find something.

It looks like there is one driver for both the small VFD and the large one, so my bet is that it is the VFD itself. I have a couple of right hand drive Japanese digital clusters that I pulled apart a while back. I noticed that the small VFD is identical between the JDM RHD one and the European LHD one. I swapped one of the JDM ones into the European cluster and it works fine. I have a couple of them, so if you want to try one let me know.

Here is the Pic of LCD.I was wondering this black spot in the right corner,is this ok.I mean I see on both of yours it is visible.Then again as i disassembled the speedo,it had also two of these marks,so i think this is ok.
