Hi
I have a KV-C292 Sony TV (chassis AE-1C) which is recently showing a lighter horizontal line in the middle of the screen.
I?ve found R530 open. I?ve replaced the vertical IC (TDA8170) and all the components (excep the two transistor Q505 & Q506) around the vertical section, but th vertical doesn?t open.
All the tensions are ok.
Do you have any idea about it

Check to see if the new parts you put in are damaged again, since you did not locate the original fault that did the damage.
It is important to verify the supply voltages, if there is vertical drive coming from the scan generator, and if all the caps are good. Many times, a cap may become resistive (leaky in resistance), or opened (high ESR), thus causing these types of faults. You will need an ESR meter to properly test the caps.
