Hello everyone,
I recently purchased an IGT 1982 Draw Poker machine with a Sony monitor that displays an image with distortion and tearing, as shown in the attached images. The screen flickers and diagonal lines scroll down the screen. I tried replacing the 7407 chip as well as replacing the microprocessor board for another microprocessor board that I had, which did not make a difference. I also tried unplugging and plugging back in all the connectors to no avail.
I'm not sure what I should try doing at this point. The 26-4200-16S connector that connects the monitor has very loose pins, should I replace this connector?

Dragon:
From what I understand the Sony monitors are hard or impossible to repair. Of the 4 Fortune 1 games that I own only the oldest, the 21 Game has the Sony. This game is also the least clear of them all. Not BAD but not sharp.
Perhaps the entire monitor can be swapped out. If so, I know where a few brand new monitors in the box can be had. I hope Badbaud can chime in for a more technical response.

I'm not a monitor tech but that looks like it could be a vertical foldover problem. When you said you replaced the microprocessor board I assume you meant the slot machine's main mpu board, not the monitor control circuit board located under the crt? If so maybe you can find the schematics for the monitor, replace capacitors in the vertical output circuit. There should be some electrolytic capacitors in there, one or more may have gone bad over the years. In fact, there are places on the internet that often sell what are called "cap kits" for different monitors, you could order one of those and replace the caps they suggest, it may take care of the problem. You will need the Sony model number, it should be on a sticker or stamped on the monitor chassis someplace.
Have you tried tweaking any of the vert adjustments on the monitor? Don't get them too far out of whack, turn one at a time slightly, if it doesn't help then put it back where it was. Otherwise you could create other problems.
Was this problem why the machine was sold to you? Would be good to know if the previous owner tried replacing anything to attempt a repair.
Depending on the cost you might want to just replace the monitor. There may be some different brands of monitors that will install easily and get your machine back to working.

I remember those monitors from when I was young and healthy.
The warehouse would be littered with piles of discarded antennas, plastic enclosures, and Sony TV empty boxes.
Considering the age of this kludge try exercising your controls back and forth before setting them.
Those pots are very old and they get their carbon all mucked up.
Some vigorous swipes back and forth helps the wiper dig into the dirty carbon and make a better contact.
Conversion?
All of the monitor signals come from a plug on the backplane board then terminate on the Sony connector.
AC power is a separate connection.
A lot of Fortune I games have Ceronix monitors in them and some have older RGB monitors.
The monitor connector was modified for providing video signals to these monitors... so it can be done.
Get a pinout for, say, a Ceronix monitor, match the signals to the pinout of the monitor connector on the FI's backplane board, add AC THROUGH A 1:1 120V ISOLATION TRANSFORMER, Unless it has already been provided, follow the separate AC connector back to it's source, it should terminate to a 1:1 transformer. If not you will have to add one.

Thank you all for the suggestions, folks. The guy I bought it from claimed to have had it for a year, and have the monitor work fine until he was cleaning the insides with a compressed air duster a few weeks ago. He says he never removed the monitor. I suspect the monitor may just have failed spontaneously and it was merely a coincidence.
I am interested in taking the Sony monitor out and putting in an LCD screen. Does anyone have a manual for the machines that have the Sony monitor, or for the Sony monitor itself? It seems that the connector type and pinout for this monitor is different from what is described in https://www.arcade-history.com/manuals/33008/fortune_i-manual-IGT.pdf (https://www.arcade-history.com/manuals/33008/fortune_i-manual-IGT.pdf)

That shows the next generation RGB monitor.

Compressed air can generate a high level of static electricity because it is moving so fast. That may be what zapped the monitor electronics, but who knows. One of the principles of dealing with electronic chips is to be very careful with regard to static electricity. This is also why you shouldn't clean a circuit board with a vacuum cleaner, esp using a plastic bristle brush attachment. Just about anything non-conductive like dry air that is moving quickly, plastic bristle brushes, the synthetic fibers in carpet, clothing like shirts and pants that have synthetic material (such as rayon, nylon and similar) can all create thousands of volts of static electricity when there is a movement like rubbing them. That's where that spark comes from when someone walks across carpet and touches a door knob. Static electricity damage to electronics is real but it is hard to prove.
