Millipede no picture

[Tea]

Hello everyone, I've got an issue I'm a bit stumped on. I have a Millipede that was working great, recently it developed a bend (photo attached) the screen also went dim. I took the chassis out and recapped it and put it back in the machine, no picture at all. I took the chassis back out and cleaned it, then looked it over for any cold solder joints, I only found what I believed to be 2, I re soldered those and put the chassis back in. I still have no picture, however, every now and then when I power it on I will get a picture but it has a weird "overshadow" on the letters/numbers (piucture also attached) and then the picture completely goes away again. Very rarely sometimes there will be a blotchy flash that shows up on the monitor but no game.

Is there anything I should be looking at? I do not have a test pattern generator to test if maybe its coming from the game board.

Thank you in advance!

you have a Matsushita TM-202G. the plug you should be connecting should have 5 wires in a row, since the TM-202G has a unique pinout from other monitors. so I suppose make sure you're using the right signal plug first (as I think that's like 1 sync vs. H+V)

when it's black, try turning the Screen pot on the flyback up to see if the screen shows you a grey box. you can rule out the issue being with the tube or heater then, and it will be something else. the signal feed is a separate board as I'm sure you're aware, cause that's where you plug the signal from the game board in. make sure all the plug interconnects between the different boards (I think there's 4?) are all good.

beyond that I don't have much experience with these, I've never really needed to fix one, so I can't offer more help.

I did double check with the video I took before hand that everything is exactly how it was, on the fly back I did try that originally and when I turned it all the way up the first time I did get the lines that appear when it's too bright (raster?) but then after I lost picture again adjusting the fly back does nothing. I still have neck glow

As a side note the game worked perfectly for about 9 months before this happened
