Neotec Nt-2701

[powerplay]

I am working in a couple of neotec's Nt-2701.  I got one that's ticking, one that has high voltage and no video and two dead. 

Let's start with the most recent (the ticking sound).  When it was received from the road tech, I notice it needed a cap kit along with a new flyback because it had a hole on the top of it.  I did a complete cap kit, replaced the flyback, replaced Chiclets caps C423, C421,C419 & C450.  I checked the high output but it was not blown.  When I power it on for the first time nothing came up, so i turned it off and took it off the cabinet. I then notice it blew the high output.  I replaced it and nothing again doing a ticking sound.  I had this same problem in another Nt-2701 and once I replaced everything mentioned above it worked perfect. But this one keeps blowing my high out puts and keeps ticking. 

The second board has high voltage, I can see the nec in the crt glow but I have no signal. No video what so ever.

The 3rd and fourth board are dead completely and they keep blowing my high out put.

All these boards have cap kits put in.  All boards also have new flybacks put in except one of the dead ones the other dead one has one new one as well.  the Chiclets caps have also been installed.  I don't know where else to go from here, usually this takes care of the problems. Any information is appreciated. Thanks guys
