LCD monitor turns off after a second

Same brand? Same model? What brand? What model? What signal?

My analog tv wasn't working right, for a whole hour. Then I noticed somehow it had changed to channel 2 from channel 3.

Caps don't have to be "bulged" to be bad. Is controller shutting down for an overcurrent fault, etc. (or, is the image still visible even w/o backlight(s)?)

Typical of inverter shut down due to detecting an unbalanced load on the cold cathode tube drives. Can be the tubes or inverter faulty. Most drive control IC's have a pin that can be forced low to disable this protection feature for fault finding.

Hope that helps John.

Hello,

How would that work, i have read about the possibillity to disable this protection but i am not sure what chip and what pin, you mean there's a pin i must put to ground? or open the circuit for that pin? Can this problem be caused by bad caps, the monitor in question had bulged caps but i only replaced the bulged ones, the monitor worked fine for 2 weeks after that and now shuts down, shall i replace the remaining caps? They are close to the voltage regulators on the power supply. Thanks for helping, i get a lot of screens that have this fault.
