Can anyone identify which stk/ics need replacing if i send a picture of the cuircit board(convergance way off)also is there a easy way of removing high voltage cables from the board or the block .the manual states a 90 deg turn but these things won't budge.already busted one.where can i post picture

There is almost nothing that can be fixed by yourself if your not trained in high voltages and advanced circuitry now days. This sounds like it could be your color guns going bad or the power supply.
This set also has an issue with The tv convergence board,require 2 STK convergence ICS and some or all it resistors to replaced to solved the tv convergence picture problems.
Not any amplifiers problems.The problem u having it known as covergence problems,it dead.The tv colors lines R,G,B mis alignment,have colors pictures shadows or 3D look like pictures.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts,must be replaced on the convergence board to solved the picture convergence problems.The Shop,will cost u $300-350 for parts and labors.
3d colors not lining up poblem dicates "convergence issues.. bowing piture may indicate complete faliure of convergence alignment cuircits... depending on model the most likely cause will be 2 micochips (ic's called stk<s)
C8011 could definately cause the problem you are indicating as one side of that capacitor is tied to the postive feed for Red horizontal in IC8001 ( STK392-560) and the other is tied to the Green vertical return . I would replace that along with the IC as the IC is sure to be weakend if that capacitor has shorted. Let me know if you need further assistance.
You must have checked fusible resistor?
check convergance control panel and check voltage supply to this board.If voltage are o.k than you have to change convergance control ic which is smd ic and its on the control board.
A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.
