I can't get the curl out of the left side of the display.

step back saver system
that tube is in full overdrive/out of foucs etc
blance it back out first
ie turn screen down and tweak in foucs
then repost

plus next time yes 99% of all monitors need cap kit's

no need to ask that q,i have seen u fix enough of them now to know this
as routine

I just wanted a 2nd opinion. The pic is out of focus because of my cellphone camera. Its actually a pretty crisp picture on the screen, just not on my phone.

ok it had me confused.:)
but to answer your q
u are getting fold over
this can be 1 of 2 reasons
a=exssive drive
b=bad cap's
go with cap's if the pic is sharp and crisp
just look's like it is beening over-driven is all

OK, I'll check the overdrive first.

This is a "barn find", but not a speck of dust on it, and it's not very old. The jamma board is even spotless!

I checked the caps for physical signs of damage, but they're all nice and sparkly. No leakage, domed tops, etc...

We brought it home, fired it up, set the V-Hold and this is as good as we could get it. I didn't touch the screen or focus.

My rule is: If it's been more than 10 years since the monitor was re-capped or if I don't know when it last received a cap kit... then it needs a cap kit.

When I get a new machine I ALWAYS re-cap it as part of my general tune-up procedure... whether the monitor "needs" it or not.

You'd be amazed how much better a picture looks after it, even on monitors that seemed perfectly fine before recapping.

Monitors are mostly analog circuitry and as such the quality of the resulting image is based on how finely tuned all of the voltages are within that circuitry. The older caps get the less accurate they become and the worse the picture on the screen gets. you shouldn't be waiting until it gets so bad that something breaks.

I look it like changing the oil in your car... you change it regularly because it wares out and looses it's effectiveness... you don't just keep running it until it gets so bad that the engine no longer runs right.

caps can go bad just by sitting. the rubber on the bottom that seals the can up drys out and allows the electrolyte to dry up.

irrespective of it's power on hours, it's caps were made 20 something years ago... nothing lasts forever, especially these days.

capkit.
