Thanks for the info guys.
Turned out the customer bought a new TV and gave me this one for hooking
up the new one.
It did turn out to be Q3404. Cx3418 was ok but instead of being a 470uf/50v
it was a 1000uf/50V. It looked like it was that way from the
factory. Have you ever seen any 9-520-6 with this modification?
Thanks again,
Doyle
