Quoted from TigerLaw:

Well, my monitor took a crap on Saturday so it's time for me to read up on this switch out. Doesn't seem too terrible.

Awe man....beyond repair?

Not really sure. Game will power on and play but no monitor. I'd been wanting to install the LCD display anyway.

Quoted from Crashnburn:

Applejuice, will this put 5v on pin 9 on the VGA connection so you do not need a video amp if you are keeping it stock?

Currently that pin is wired as per the original card, though I can add this to future runs if it's something that's wanted.

You can currently choose between original mode and sync converted mode

As long as your tube had a good picture, the chasis can be sent out for repair very reasonably.

When my monitor died (tube bad)... I spent too much trying different LCD panels but was never satisfied as they all put out too much light in their black. Its not something you notice when normally viewing but in P2K excess light up there is very noticeable, for me at least.

In the end I found a new tube monitor and love it.

Hmm, will have to consider the options. Thanks for the suggestions.

my guess is that you might just need to put a new cap kit in your monitor. do you get any picture at all? or does the monitor make any noise when you power up the machine?

if you're comfortable soldering, then it shouldn't be too much of a problem. I've done about 5-6 now for arcade monitors and this is no different. just make sure that you ground and short out the flyback before working on it (the voltage stored up in those large capacitors is enough to kill you

Thanks for the response! It just kind of goes on and off. The game still plays, just with no monitor. Loose connection I'm sure. I've been pretty tied up the last month or so, hope to getting around to this soon.

FWIW The converter pcb will work by itself without a sync dongle added. The old converter with one vga out are the problem pcb's, With this pcb go into menu >> geometry and adjust the v position to like 28 and see if it will sync. The newer converter with 2 vga's out will sync with no issues without the sync adapter too.

This might be a stupid question but why can’t you just plug the lcd monitor straight into the computer with a vga cable?

Thanks in advance

This will not work because you have to convert the output from CGA to VGA.

Because the video resolution out is not compatible with what a modern LCD can understand. Pinball 2000 computers do not output vga natively when the prism is connected

Struggling to find 74ls02 locally, I’ve found 74ls09 and 7402. Can anyone recommend an alternative if any?

Thanks in advance

#65 10 months ago

I guess the question is... can I use the 7402 instead of the 74LS02?

If anyone is switching to an LCD that has the original WG monitor, I would like to buy the CRT from you. I'm not a fan of LCDs and I have the crappy non-WG monitor in mine. Thanks.

Your best bet might be to try to steal one from an arcade game. I’d post a wanted on an arcade forum like klov.com.

Thanks. I've looked. The issue is it's a 7300 series monitor, which is not common in arcades. I'm following some leads and I hope to find one.

Sorry, didn’t mean to give misinformation. I believe my SWEp1 has a replacement monitor. From memory, the wiring just needed swapped around a little. I’ll check it later and take a picture if you want. I haven’t looked in the back of that game since giving it a cap kit about 6 years ago.

It doesn’t need to be that model. You can make any 19” standard res color monitor work in there.
