My problem -
Relisys TE770-RU 17'' CRT Monitor
When my monitor was working correctly, I would plug in the monitor, the green power light would come on for a second, then it would turn amber (power down, I believe).
Now when I plug the monitor on the power light simply flashes and there is clicking noise, I have to repeatedly turn the monitor on and off at the plug switch to get it to eventually come on properly. I noticed this was worse in cold weather or in the morning when it was cold.
I tried an experiment, I placed a fan heater a couple of feet away from the monitor and switched it on for 15-20 minutes then turned the monitor on, It came on as normal. I've tried this a few times now, even in the morning and it comes on as normal. So when I warm my monitor up in this way it works as normal.
I was wondering if anyone had any ideas what the problem might be.
thanks,
mike
It is a weak cathode heater inside the CRT. One fix, besides what you are doing, is to replace the glass tube (crt) inside the monitor. Unless you can find a used one, may be hard to find now. It may also be possible to supply the heater filament with a separate supply. I believe this requires a 6 volt supply, so try adding a 10 volt (FUSED- 2 amp) supply to the filament only.

i have the same problem but with a flat screen. it just flashes a green light every five seconds and makes a clicking noise from the front of the monitor. the screen stays black. this happened once in the summer and after about an hour it came back. now it is the winter and it's been flashing for over twelve hours now and still black. could it be the same thing?
