Sony KP-46S25 Burned resistors

I have this Sony Projection TV in my shop, at first it would try to power up and would shut down. I found a 330k ohm resistor on the power supply board open. I replaced the resistor and made several other checks for the notorious "Ring Cracks" and loose solder connections and resoldered as needed.I also checked various resistors, transistors , voltage regulators, horizontal output etc... Upon inspection of the convergence board I noticed a 3.15 amp fuse open, and the smell of burned resistors. I removed the heatsinks for the convergence outputs and sure enough I found 5 resistors burned black. I need to know what the value of these resistors are, they are as follows:
R-1610, R-1613,R-1615,R-1619,R-1621 I have the STK392-010 outputs on order. Any and all help would be greatly appreciated.
