Everthing on the monitor is like lookIng through a mirror

Anyone have any ideas why everything on my monitor is reversed like looking through a mirror?

Could be a couple of things.

1: dip switch setting on your game board.
2: software dip switch settings on your game board changed and never saved when the battery died.
You can re change the settings and re save them. If they do not hold after the machine is powered down. Replace the battery on the board or Dallas chip.

3: The deflection is reversed. Not H to V but the connector for I believe the Horizontal deflection is turned 180. So if it is the H deflection connector pins 1 & 3 to board conector
pins 1 & 3. It was flipped to Connector 3 & 1 to board connector 1 & 3.

What game is it? Did you just turn it on one day? Or did you buy it this way.

Thanks for the advice, I will check out number 3 shortly. I don't think it is 1 or 2 since I already set up the dip switch and there are no batteries on this one.

It is a Rally-X cocktail that didn't work when I bought it. I found a bad TIP31 on the power board and brought it back to life, but now I have this monitor issue.

All the connectors can only connect 1 way, is there any other way this could be flipped?

I checked all the connectors and they can only go one way. I also put it into another machine and had the same results, so it must be the chassis. I have a cap kit on the way because it really needs it, but I don't see that solving this issue. It's a WG K4900 if that helps. Any ideas or help is greatly appreciated.
 
some people think "flipping" yoke wiring means you take the vertical connector and plug it to the horizontal and vice-versa. some monitor manufacturers made these connectors different sizes to prevent doing thing.. but if anyone's ever split those connectors before or whatever, yeah..

you're just unplugging one of the connectors and turning it around. if you have green/yellow plugged in, make it yellow/green.

there's no way they can only fit one way like that. and what happens if you mismatch vertical/horizontal? bye bye yoke.

I've attached a couple of pictures. The first shows the yoke end, all four wires are soldered and look original. The picture shows Red and yellow, the other side was too hard to get a good picture of, but is white and gray wires. The second picture is the other end of the leads which has a connector that goes to the chassis. It is made such that it can only go on one way and has not been cut or anything. If I were to de-solder and switch 2 wires, which two would I switch? I really don't want to cross H with V.

you wouldnt want to desolder the wires. What I do when that happens is seperate the connector. The red and blue are a pair and the yellow and white are a pair. the red and blue have a wider pin spacing, so they can only fit on two pins on the chassis.

Someone may be able to explain it better....lol

break the connector in half (yellow/white on one side, blue/red on the other)

reconnect the yellow/white half exactly where it was pulled from.

the blue/red half, reconnect it to the same pins, but flip it around. easy way to tell how this goes: the jagged edge from where you broke the whole connector in half should face AWAY from the yellow/white part.

your image should now be reversed back to the way it should appear. and if it's a game-related problem with the flip, don't worry about it, this adjustment doesn't hurt anything.

EDIT: maybe someone should lend a helping hand with how to "break" it in half. lol ... dremel with cutting wheel? electronic shears?
 
Before swapping the wires, check if the monitor has another connector to invert the image! For example, Hantarex, Sanyo has generally two connectors for the yoke: inverted and non inverted
 
Monitor flip

It looks like the WG 4900 dose not have away to invert the picture.

Take a piece of paper draw out the connector on the board with references of other parts around it.
label the pins on the board with there present colored wire match up on your piece of paper.
Take a pair of side cutters cut the connector in the middle . seperate the newley created connectors for H and V as described above.
Place one of the connectors in the same position with the same wires going to the same pins on your piece of paper. Flip the other connector 180. Turn the game on and look at the results.

If it is not what you want. then return the connector that you flipped to its original connector to pins on the monitor board lineup and flip the other connector. Turn the game back on and view your results.

Damn...you got it working? pics or it didnt happen lol

What boardset ended up working?

LOL, yeah turns out both power boards were bad as well as 2 out of the 3 pcb's. I was able to get the power board that looked like it had been recapped working by switching out the TIP31 from the other power board. It wasn't outputing 5V to the PCB. I'm not sure which boardset worked, they all looked the same lol. I've got a cap kit on the way which will hopefully fix the vertically challenged monitor! Now if I could just find a new glass top...

Thanks again for the games and monitor, I'm really looking forward to learning all the EM stuff on the Pin.

awesome man....go you :)
I swear I replaced that TIP31..although i guess its possible I could have gotten a bad one.

Regardless awesome to see it working..Rally X is a fun game.
