a52-3,6,9 keys problem
 

I have a problem with 3,6 and 9 keys, they don't work. I cleaned it in ultrasonic but it's still the same. What are the keys lines. Is it directly from processor like in older models or thru any resistors, capacitors?

directly from cpu, You must desolder CPU and repair broken tracks
