Re: screen stays blank after turning it on.
The blinking pattern you're observing is a result of a heavy current load on the power supply. The power supply could be defective but more than likely the scan or sustain boards have a direct short on them causing the power supply to shut down and display the error. A technician will be able to determine where the load is coming from and replace the appropriate board or component. I hope this helps you.

When you mentioned blank does it have light on. If not check the filter for cloggging as the heat build up on the lamp can trigger a stop. Use a good forced cooling to confirm.
If the picture is clear and there is no illumination issues the bulb must be good and the issue may be power based.
If the main power supply can be cooled off , does the fault apppear, if so check the soldering of the power supply.
unless all this is confirmed the problem of the suspected bulb can stay.
Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on? If stays on, then inverter turns into protection mode because of old backlight lamps. If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.
