Hello all!

I have several 28" arcade monitors. Some work, while others have these problems. What could be the cause? Should I repair them?

Thanks a lot for any replies or suggestions and have a good day!

Hi, do you have more details? The make and models specifically. The 2nd picture looks like vertical collapse and in the first picture there's at least raster so there's hope for them.

Do you have experience working with open crts? I'm just asking for safety reasons - crts can kill you even when powered off and unplugged if you don't discharge them properly.
 
Thanks for the replies :)
Yes, I know the risks involved in handling these monitors. I've repaired two cabinets, but they obviously didn't have this type of problem.
Thanks for the link, I'll watch the videos and post more photos and details about the monitors. Have a great day!
