somebody gave this description in another post of same problem

"the Vertical Sweep IC at U2 (TDA1170A, 12-pin)"

-

what chip is that?..........I cant see a 12 pin chip on the se/30 board anywhere!............is this chip on the analog board?

-

I have metered out all the Ux8 chips and compared them to a good board. EVERY PIN IS CORRECT

-

is there anything else that's would cause the horizontal line.

-

would it be worth metering out all the pals
