Hey guys, I think this may be blasphemy on this forum, but try not to cuss me out. I am thinking about replacing my monitor in my NBA Jam TE with an LED one. This CRT is just pretty much gone after 20+ years in service.

Questions:
1-Where is the best place to buy one?
2-I think the guy told me it was a 25" one, do they make that in a square?
3-What else will I need to buy?
4-Is this something I can do myself
5-How do I not get electrocuted? i.e. how do I "discharge" and dispose of the old monitor?
 
Wouldn't recommend a non-CRT, but you can read a dozen explanations in other threads...

Sure about that? Lots of fixable things can lead to a "shot" image.

Alternately, you can find videos on you tube. FWIW, I ground to the DAG wire instead of the chassis and leave my jumper clipped DAG to anode until I'm ready to put it back together.
 
If it's got burn in i could see looking for a replacement tube, keep in mind a led/lcd arcade monitor will run you at the very least $400 +/- shipping. while getting a used crt can be had for free-$125, infact i know of a few for under $100 working complete 25". the tube you could get crafty and go looking for old tv's :D
 
All over my head

All of this is over my head. I wish there was someone that actually wanted to work on these things in Raleigh, NC.
 
What are the monitor symptoms that you're calling "gone"? You can always send out the monitor chassis to get fixed. Plenty of guys on these forums fix them...
 
Describe the monitors symptoms and/or take a picture of it for us. It might just need some minor adjustments.
 
Don't put an LCD in there. It'll look like crap. Fix your old monitor. If the tube itself is worn out, you can replace it with one scavenged from a television set.

If you do wind up replacing the entire monitor, don't throw away the old one - offer it up here, someone will need it. These old monitors are very fixable.

repair

A guy just came in that knew these things well. I think he said the tube was done. I think the rest of it is good. That being said, where should I go from here. It is bleeding and the colors are starting to go. I still have red, green, and blue though.

Take a pic of what its doing and someone here will help...

First, tell us what monitor it is, and take a picture of the screen. If it's a K7000 (common), they were known for the tubes going weak (especially the Zenith branded ones).

A weak tube can be "rejuvinated" with a picture tube tester, zapping the contaminents off the cathodes and making the picture better... but it's hit or miss - might fix it, might not. Any TV repair shop should be able to do it for you.

If the tube really is done, then start looking around on trash night for 25" TV sets. Take the back off and compare the neck connector with the one on the arcade monitor. If it's the same, then unplug the yoke connector and measure the horizontal and vertical winding resistance, and compare that with the arcade monitor's yoke. If they're pretty close, then you should be able to just swap it out (might have to change the plug on the yoke).

Do some reading on monitor repairs in general - there is a big long sticky thread in the Monitor section on basic arcade monitor stuff (it was written by some loser with way too much free time), that covers the basic theory, what parts are what, how to discharge, etc.

It's not hard to fix it yourself, and leaps and bounds cheaper than buying a new monitor. But be prepared to do some reading, some learning, and some work. If you just want to go the easy way, buy a working/rebuilt monitor from someone here, and trade/sell/give away your old one.

But first, give us some more information on your monitor, it might not be the tube. We'll want the model number, and a picture of the screen to see what it's doing.

not positive but is it the one in your NBA Jam cab? not sure if your cab is a dedicated midway cab but if it is, it's prolly a 25" WG K7000 or Hantarex Polo. snap the pics we'll figure it out.
