Installed a new flyback, installed new HOT, removed and checked R908 okay, have good high voltage all over the chassis, no blown fuses, nothing smokin.lol just cannot get the tube to light, so I'm stumped...IC501 chip was replaced at some point seated into it's own socket where I guess the original chip was soldered directly onto the chassis board, only shows 2.7Volts, seems low so I'm thinking something is drawing down on that chip.
I'm not positive IC501 is even a problem, just going through the process of elimination, of course no voltage readings on the factory schematics so I can't even test for proper voltages...checked for cold solder joints, broken traces, reflowed the typical problem areas on the chassis but no glow on the tube neck...pulling my frickin hair out with this thing...anybody know what the proper voltages are on the key points for this chassis.
