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.

Hi Bart,

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)?)

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.
