[mikkhh]

yes can program in circuit, I cut the lcd legs with side cutters then solder back together. It is quite hard to solder off lcd, I have done that too...

This is problem, I use tl866cs

[Diagcar1]

Could be your programmer or the connections to the programmer.
With a good device/programmer you can read/write this one without any problems.

I use original UPA for this reading in the circuit, you have to use only 6 wires 1,2,3,4,5,8.
In your photo I see that the eight wires are connected.
And lower the voltage to 3.3 volts

Thanks, now the programmer is "work" but..
