Strange monitor problem

[daeven]

I've got an "old style" Eygo 19" monitor that has a nice picture when nothing is moving on the screen.  When things start moving, the picture shrinks and expands about an inch around all sides a couple of times per second.

A while ago I replaced most of the capacitors, possibly missing a couple of the smallest ones.  I know my next step is to finish that job, but does this sound like the kind of problem that a complete cap kit is likely to fix?

Posible problem it was in the power supply sheck all the capacitor electrolitics after the br.rect. and power for horizontal zone. Other problem is posible Bluming, when the pot. for control the bright or contrast is move the picture came back and forward more big and saturada, this problem is a monitor, need reactivation or new monitor.

Finish the capacitors first. If that doesn't correct it, then get out the high voltage probe and measure the high voltage. If it's less than 19,000 volts then your flyback is going bye-bye. Your condition is known as "blooming" and is caused by the high voltage being lower than normal.

I just thought of something else---by chance are you running a monitor intended for 120 volt power in a 100 volt Nintendo cabinet are you?

No Nintendo cabs here.  Thanks for the pointers.  Assuming the worst, does anyone know where to get replacement Eygo flybacks?  I notice Bob Roberts doesn't have them.

How about combining the perfect picture tube from this monitor with the (repaired) G07 chassis from my other post?  Any chance they may be compatible?
