I've asked this question a couple times before, but I'm putting this together one last time to see if anyone can help. I am probably a couple days away from junking this monitor.
Seemingly at random times, I will power-on the monitor and it will make a loud squealing noise, and an audible crackling. Looking at the back of the monitor, there are blue sparks flying all around the anode cap (inside the monitor). Turning it on and off a few times, it will get less and less noticeable, eventually to the point where I can leave it on.
If I do leave it on, the display will eventually come up and looks fine. The screen can look completely normal even while the crackling sound is happening and some blue sparks can still be seen. I am afraid to bring this machine into my house (in the garage right now) like this.
Here's what I have done to try and fix this:
- Put in cap kit
- Put in new flyback
- Insured that the lag (?) spring is grounded to the chasis frame
- Removed anode, cleaned port on tube with alcohol, blew out with compressed air
A local TV guy said that there used to be a spray that could be used on the port where the anode attaches that would help insure a good connection. I haven't been able to locate this yet, don't even konw if it would work. If anyone can help save this monitor, I would really appreciate it. I need something good to happen here, or I will be trashing this monitor. I just wouldn't have peace of mind having it in my basement with this problem.
