The Destroyer;..... $12 sounds awful cheap for 2 Sanyo ICs... Are you SURE that they are REAL Sanyo ICs ??? HOW ?? You missed one;=>... How much electronic/TV repair background experience do you have ???? OK , it took me awhile , BUT , I found one... I have schematics , but , NO pix of ANY boards... Let's start with measuring the B+ for the Convergence ICs... I have a "Block" diagram that shows connector "KF" near the rear of the chassis... It comes off the board that has the flyback on it & connects to the "Main" board.... There are 19 pins on that connector.... Pin #19 should be the farthest toward the rear of the chassis... Pin #1 should be the farthest toward the front of the chassis... Check on the board for labeling that says the pin numbers to verify... Pin #1 will have 110 vdc... Just for reference...NOT for convergence ICs... Convergence B+ is on pins #8 , 9 , 10 & 11... Read all 4 pins... Should read about +24 vdc... Convergence B- is on pins #18 & 19.. Read both pins... Should read -24 vdc... Read all voltages using one of these pins as your ground connection for your meter... Pins #12 , 13 , 14 , 15 , 16 or 17 ...(Same connector..KF..) Post results... Thanks........ Later...Ron.M....... Veteran & Retired TV technician
