My Flyback burned on my Bosconian with WG 19K4606. Since this monitor org. came from a pacman, it has a lot of screen burn of the pacman in it. I was just looking for an entire new chasis rather than find a flyback for a poor screen. My question was if a 19K4903 would be pretty much a plug and play swap for my 4600, or does it involve a complete re-wire of the harness plugs?

Got a line on a complete perfect looking 4903 for less money than a new flyback for my 4600 would cost.

thanks in advance.
 
Some K4600s had different interface cards in them, with various pinouts. I'm pretty sure the later ones had the now "standard" pinout, and should be plug-compatible with newer monitors (like a K4900).

Look at your interface card (the one the video connectors plug into) and see what "P" number it has. According to this: http://www.ionpool.net/arcade/tech/19K4600_pinout.txt if you have a P306, P317 or even the P298, it should be the same as the K4900. If, however, you've got a P297 or P302, a little re-wiring may be needed.
 
Thanks for that link, I printed out that page. I did not see my 4606 on that list, but I believe my 4606 is a neg sync also.
 
The 4600 yoke and 4900 yoke are NOT the same, so you can use the same tube, but have to swap the yoke. Once you swap the yoke, you can put whichever chassis that matches it on it, as the yoke connector will match the chasss. Video connectors and power connectors from the game will plug into both with no changes, assuming no one has altered the original power connectors.

Also, the chassis mount to the frame in different ways, so you may have to adapt or swap the frame for an easy swap....
 
I might be wrong, but I understood from the OP that he wanted to swap out the entire monitor... not just the tube, or yoke, or chassis... but pull a K4600 from his cabinet and install a K4900.

Just covering all bases. Don't want someone to stumble on this thread 2 years from now and think, "Hey, I can pull my 4600 chassis off and stick a 4900 chassis on!"
 
Thanks for the info guys. I will check the interface card on mine. What I really would like to do is buy this 4903 complete monitor and chassis and put the whole thing in as a complete replacement for my 4606. This is why I was looking for info on the plugs for the power and such if they was the same connectors and wire diagrams. For the price of the 4903 I am looking at, I may just buy it anyway. My 4606 was made in 81 and the 4903 is from 85. It came from a private game that never saw public arcade use. My connectors all look original.

Yes, that is it exactly. Pull the entire 4606 from my cab and install a 4903 in its place.
 
you'll also need to make sure the new K4900 has a frame that's compatible with the Bosconian cabinet... it needs to be either a horizontal mount or universal mount as it must have the mounting brackets on the sides of the monitor, not the top and bottom. chances are pretty good that it'll be correct but it can't hurt to double check.
 
Thank you for the continued feed of information. Turns out after digging into my machine some more that I have a 4606 vertical type monitor and tube mounted on a 4626 chassis with a recent re-cap. I have not identified the interface yet but it maybe the P317 after seing the black knob on it.

The 4903 I am looking at is a horz. mount with the mount tabs on the sides, so the mounting aspect should be easy.
