I have an envision CRT computer monitor that all the sudden quit working. It will "power up" but the power light will be very dim. Then it tries to come out of standby but then you hear the relay click again and it shuts off (to standby again). I took it apart and re-flow solder joints that looked bad but still the same thing. Oh yeah something werid. When it is plugged into the computer it does what I described above but when I unplug it all the lights on the front flash at full brightness (remember when its plugged in the power light only dimmly glows) weird eh? does anyone have an idea where the problem is?

I imagine there is a problem with the CRT power supply or tube it's self. Monitor's that are reasonably recent are pretty smart, they will only try to fire photons at the screen if there is a cable connected & its receiving a signal (unless its one of the ones that says signal lost). A possible reason is that the CRT tube is drawing too much current from the power supply causing the voltage on other modules of the monitor to drop, this would result in the dimming of the LED's...

Its just a guess though...
