Kortek KT-2938F

[arcade nut]

Tried 2 find the schematic to a Kortek KT-2938F  but to no avail  have to much red and was going to pull trans. but it aint got none  or to many,(6 small ones) I think I can pull res 822 on the neck board and it will do the same thing,, it is going red when it warms up and I want to make sure it isn`t the tube.
thanks in advance, Robert

lm2405 is your gun drive chip
it is on a heat sink
looking from the top down with board off of neck it will be on your right
the small tranistor's are pre drive's

going red after warming up ?
go to menu/advanced reset color tone's
if that dose not do the trick menu/advanced and adjust
if it still lean's red have the crt chked

Thanks so much, even sprayed everything I could think of with freon and didn`t help, and I was very scared cause u know what happend when u spray hot glass with freon?? ,, acually it seems like purple after it is warmed,,, it looks good when you first turn it on
