LA78040N Input Pin Number (Sanyo TV DS19204 Vertical Deflection)

"Kip",



I can't believe you asked that question, "R u sure its not a LA7840"!!!!



This TV is less than a year old with a new (I assume) type of vertical deflection IC. The IC number is LA78040N. When I searched the web for pin out information, all I found were sources where I can order this IC.



I will be very grateful if someone could tell me which pin is the input pin? I know I can find out via circuit tracing, but I already put a lot of time in this 19" TV, and the customer doesn't want to spend a lot of money to get it repaired.



Thanks >R u sure its not a LA7840

I confess that I was thinking the same as Kip.

The LA7840 is still current:

Here is a datasheet for the LA78040N (first hit with Google):
