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,
The small wires are disconnected at the focus and screen control block, and the large HV cable is disconnected from the HV splitter.you may have to reuse the large red wire if the new flyback doesnt have the HV lead attached. The Hot is the horizontal output transistor its mounted to a aluminum heat sink near the flyback.
I am assuming you need to get the HV lead out to remove the board. That model if I am not mistaken has the one large Red HV lead running from the flyback to the HV splitter where the other 3 large wires run to the CRts. If this is the case the trick is to remove the wire from the flyback at the splitter, I have found its easiest to slide the red rubber boot back then use a pair of pliers with tape on the jaws so as to not hurt the wire then grab the wire as close to the splitter block as possible then using a second pair of pliers like a hammer and hit the pliers holding the HV lead and thst will force the HV cable out of the Splitter block.
Changing all the caps is not the right approach
to problem solving.Works cold,but fails after hot
is a thermal issue.After set warms up and fails,use cool freeze spray on suspect components to isolate.Determine whether CRT filaments are lit
and/or if HV is present.Also,inspect jumper wire
from transformer to HV block-if corroded,replace
jumper HV lead & HV block w/Mits. parts.
