Television and Home Theater

My TV recently started to have a Convergence issue and after reading about the problem it seems the STK IC's need to be replaced. My plan was to pull the board and give it the once over for cracked or bad solder connections but ultimatlely I will probably have to replace these. I presently don't have a Service Manual and not sure about the whole Service Menu piece so I was hoping someone had a copy they would part with.

I also read that some have added a computer type fan to point at the Heat Sink. Was wondering if this was a good idea as well.

I have a Sony KP46WT500 I replace the red CRT but when I turn on the 3 CRT have light on and after 15 second is turn off.

And the STANDBY/TIMER LED flash 8 times someone it said me that was the FBT ASSY is this true.

After finally finding time to trouble shoot my dead tv found the fuse was actually blown. When tested got a bad reading from an old multimeter, got new meter and showed fuse was blown. Went to Radio Shack to get a new fuse, problem being the original fuse was a 6.3a 125v. Replacement fuse was a 6.3a 250v. Does this pose a problem?? Hate to cause a different problem with the higher volt rating even though the amps are the same. Thanx for the help....
