    Was the old STKs were they STK392-110s and did you replace both of them? I always upgrade with STK392-180s they are King of ics when it comes to the 110s. Also if they are 110s chances are they are no good. You can order STKs at Electronix Parts 1-800-223-3205. Another thing go bad and recheck where you have solder make sure everything is ok there .

Did you have double image before changing the stk's ? If not then there was no need to change them.. Pioneers are known for bad solder connections especially in the power supply section.. suggest checking that when you changed the stk's that there are no solder bridges between the pins of either stk ICs

Sounds like the gun is trying to fire up but has internal problems. You may want to see if you want to tackle the job of changing it out. Check with MCM Electronics to see cost of a new gun. 1-800-543-4330 or www.mcmelectronics.com

Sounds like you lost the converigence. Have you tried to realign the convergence through the user menu? Try that first and see what happens.

Flashing Green


I would guess that your problem is similiar to mine but mine is with the color red. The CRT went out which is a 400 dollar part and who knows how hard to fix.
