Dont think they are available any more. It's becoming a throw away world.
I used to fix them.... without a schematic. Your local TV technician can often assist with repairing an older style monitor. e.g. CRT tube type.
Modern monitors are LCD & digital electronics. Although they still blow fuses & have switch mode power supplies with leaky electrolytic capacitors that stop the power supply from working.
If your knowledgable in this field then I would start with a visual of the power supply. Be careful of the shock hazards.
Try replacing the power cable. (assuming that the monitor has not lights when it turns off) After replacing the power cable if that doesnt work try a different outlet. If there are lights try seeing if you can replace the data cable from the monitor to the computer. If that doesnt work then you will want to look into getting a replacement.
If the computer is attached properly and you get the flashing lights it is due to switch mode power supply being faulty, too expensive to fix I think you will find, never seems to be anything like just a fuse I'm afraid, modern worlds tells you its time for you next monitor..... do try to ensure it aint the pc by hooking laptop or something else to this unit, or hooking another monitor to your pc to be sure but I find power supply failure is normally how monitors leave this world...
Definitely some electrolytic capacitors are blown inside the monitor in power supply module. Open it and observe any of them rounded on top, replace with proper ones. You see, controller operations with VGA and DVI inputs takes different current from the supply, that's why it may take different time until PWM chip in the power supply will decide it is time to shut down before getting smoked. Replace capacitors.
well first thing if its like mine the power cord is detachable unplug it from the tv and use a tester on it to see if power is coming thru if it is (and more than likely it is) its the psu (power supply unit)
These are all some component failure problem in the monitor circuits. This may have been caused by faulty components or overheating of the components causing intermittent or permanent failure of some components in the circuits.This causes the feedback circuits to sense incorrect voltages or currents in the circuits and turn on the protection circuit. It may also cause total failure of the power supply circuit and a loss of power to the monitor. These units should be returned to dealers for servicing. Hope this helps you .
This is a problem with either the power supply or or logic circuit. It could also be caused by a failure in the back light circuits. One of these problems has caused the power supply to go into protection mode and will not turn on due to bad voltages sensed in the feedback circuits. Return to dealer for service. Hope this helps you .
