Toshiba TV,cf30d50 Can't Post

UnimpressedWhile desoldering r421,I lost r421. The resistor is so small I couldn't find it. I would appreciate it, if some one would give the value of r421. I AM thankful for the help. ........Ozella Electronics

I have a CF35D50 (N4SS FAMILY) Service manual, may be close enough? It shows a R421 in its parts list as being a 1 Meg carbon film, I couldn't find it in the schematic. What circuit or major component is it connected to?

If it is the resistor off of pin 54 of Q501, it is 12K.

R421 connects to pin 4 of IC501(ta8870an)through c402.C404(10uf @ 50v) is also a part of the connection. The chassic of the cf30d50 is tac 9440 and board id is pb4388-1.....ozella
