I've never seen a monitor that looks like this and still works

I'm working on a Solar Quest for a guy. It was popping breakers when we first plugged it in. I two of the output transistors shorted, fixed

Monitor now works but the game board is hosed so I go and grab a Star Castle board that I repaired and put it in the game. We have a picture! Its doing this glowing thing where the image stays up, goes dark, blah blah blah. I think that has something to do with the shader board (or whatever its called) on the SQW monitor.

The plastic cover on the CRT is CAKED with dirt. I clean it off and find this underneath! Holy cripes Batman!

Any of you guys ever see a tube that looks like this thats NOT necked?

I've seen my share of impacted Crt tubes in various states working and not.
That one there is about as close as they get to be still functional.

I thought that maybe this thing was dropped. Like maybe the game hit the ground REALLY hard at some time in its life.
 
It really does.

I'm going to replace the tube tomorrow. I think theres another Cine monitor in storage over here.

If you get rid of this tube and neck it, make a video... :D It's kind of like gruesome movies, you're sad and disgusted but it's also cool as hell (but it doesn't matter because it's a movie - however in this situation it's that the tube is SHOT!)

the tube on my solar quest is identical - well except for the huge burn spot that yours has

very strange looking, not sure what would cause this but maybe its a problem unique to solar quest - it is a bit different from the others

back when you could still throw tubes in the dumpster, I used to neck them with 2x4s. one time I jammed a tube into a mountain of snow and took a picture flexing next to it. LOL oh those were the days.

Wait, you cant toss them in the dumpster anymore? :D

I used to toss them in dumpster still intact. When the garbage truck would lift the dumpster and spill the contents into the back it sounded like grenades going off (small little ones) in the back of the guys truck. hehehe....

huh. So maybe thats relatively normal for this game. Maybe the way the tube is mounted in the cab and time just take their toll on these tubes?
 
i was thinking along the lines of it being something to do with intensity mod / daughterboard thingy on the chassis
 
Wasn't it Sundance that the phosphor coating shook loose from the tube face during shipping, killing many of them when first powered up?

Looks like it may be a general problem for Cinematronics monitors, crappy phosphor coating that erodes or falls off the tube face easily.

WANTED!!! : DECO Cassette System Cages/PCB's - Amplifone M48AAW00X Tubes - Robotron Cabaret - NeoSaveMasta - PuLiRuLa PCB - Sailor Moon PCB
 
In which case it wouldn't be a Cinematronics problem..... it would be the problem of the tube manufacturer (Amperex, etc, etc).

That pattern is really strange. Reminds me of what you get if you microwave a CD for 5ish seconds.... wonder if something similar occurred in those tubes.... where for some reason (loss of deflection) allowed not only phosphor to be weakened and burned, but the way in which the voltage was dissipated at the front led to those patterns ????
 
do any of you guys know what SQ would look like on a monitor that DOES NOT have the intensity board? Will the image just be one intensity all over or no picture at all?

I ask because I think I'm going to ask this guy if I can have this tube, another chassis and a power supply so I can build a test fixture and work on CCPU's.

This tube is pretty hosed and I want to replace it today. Theres another Cine monitor outside under some boxes and I think its in good shape. At least I think the CRT is OK.

He's also got a good number of B/W monitors lying around that I'm sure I could steal the tube from.
