I started to remove the HVB and the red wires that come into the top of the block seem to be very tight and hard to remove. I really do not want to force them in fear of damaging the wires. can someone who has swaped out the HVB tell me if am doing something wrong or missing something.

Turn on very briefly and make sure the large red wire that entered the block is well away from any metal---if hear a frying sound and blink sequence is gone the block is bad( I used to put the wire into a old soda bottle as it has over 20 thousand volts coming out of it, much like the spark plug wires in a car---high voltage with low current.
The two wires get unplugged from up front behind the speaker grille. The large red wire is connected to the HV splitter up front, ( comes out hard but slides back in easy) the small red wire gets unplugged from the Focus block,
Thats the High Voltage Block The 8-598-955-12 is the sony part number but its been discontinued its going to be hard to locate. You may try www.tvrepairworld.com they may have one or possibly may be able to find one.
Hello: The first thing is optaining the exact replacement part. Next there are approixmately 12 pins on the bottom of the deflection board where the part is located that need to be unsoldered there is a slightly thick red wire coming from the top of it that goes into the splitter block and a thin red one that goes to the focus Block, each need to be removed. To get to the focus block the lower front cover of your television needs to be removed Reverse the procedure to install the flyback transformer. You may want to purchase a soldering iron and some solder wick, commonly known as desoldering braid from radio shack.
Look for hidden screws in the board... that's all I can say from experience. Plus, for the three red HV leads, Push down into the block and turn. This should release them if there is no other visible means of mechanical retention.
