CRT Repair - Need Advice If Possible
« on: August 04, 2022, 12:44:05 PM »
Hey good afternoon everyone,

I recently acquired a Gauntlet Legends cabinet "As Is" from an auction. It's in great shape and so far everything seems to work except for the CRT, which was noted in the auction as not currently working.
This is my first cabinet, and I am definitely not experienced in handling CRT's. I plan on hiring someone for sure; just had a few questions on how I should proceed in getting it repaired:

1. Is a CRT repair something that can be done with the monitor still in the cabinet, or would I have to remove it entirely first? I ask this because i don't know how to take it out and definitely don't know how to put it back in, and I don't want to mess this whole thing up.
2. Does anyone have opinions on reputable CRT repair in the Tampa Bay/St Pete/Clearwater area?

Thank you so much for your help; getting this cabinet has been a dream of mine for a long time and I am excited to be close to getting it running!

Atari Jim would be your best option, However... Flybacks are pretty much unobtainable at the moment, so if failed flyback, you maybe stuck waiting.

If transport is an issue, Reach out to Ratlfif he can also help diagnose and give you options on getting the monitor fixed, He lives in Clearwater.

I repair them. First we need to know your model number, take a pic and put it here if you dont know. not the tube number the electronic part sitting behind the tube. I would think it would be a k7500 or neotec.
taking on monitor chassis repair. wells gardner u2000, k7000 19 and 25 inch, k7201, k7203 , k4600, k4900, k7400, k7500 med rez. electrohome G0-7.. sanyo ez20
I can also build complete monitors with fresh burn free tubes.

legends run k7500s normally. it can be fixed in the machine, but most cases, you pull it out.

it's not bad to do in a gauntlet legends. it's just a heavy 27" SOB  :)


alternative: a decased 27" tv set with vga inputs can work, IF it fits the cabinet. it's been done and documented.

or a 25", but you'll need a good monitor bezel to fill the extra 1 inch gap you will have.

This was an unusual fix. Chassis was installed at some point without the frame isolation
plastic, so it shorted out a bunch of parts that almost never fail. Finally a diode that was
testing good but wouldn't pass power and the K7500 monitor was running like new again.

DIY monitor repair is never a good idea, just my self serving opinion.
