Hi, my fp5315 monitor regularly switches on and off and when i disconnect and reconnect the power supply wire then it comes on. It does this everytime i turn my computer on and also when I'm listening to music through the monitor speakers.
Any help would be much appreciated. Thanks in advance.

Re: monitor switches on and off
Normally like thise it sound like your have problem with the backlight insideLCD.There is one condition with LCD is that if the backlight inside blink or spoil then it just cut off the supply that mean screen become black.If you switch on again it work but after sometime it should should shutdown again.Ask technician the check for you,don't do it yourself cos inside high voltage...danger.

your LCD inverter is almost dead. the monitor itself actually remains on, but just goes to black each time the LCD inverter cuts out, since this is what supplies white light to the screen.
In case you wanted The FP5315 Users Guide, or 3 other HP documents for the HP FP5315 LCD Flat Panel Monitor: http://h10025.www1.hp.com/ewfrf/wc/manualCategory?lc=en&dlc=en&cc=us&lang=en&product=324205&
you need to repair or replace the power supply, the blinking means that the the voltage is not constant so it can be a problem of defective capacitors: 1000uF 16 et 470uf 25V, you have to take it to professionnel technician because it is dangerous for you, there is a hight voltage inside the monitor but if you have some knewledge about electronic and hight voltage you can do it by your self.
Make sure your computer is working properly. Hook up another known working monitor up to the computer and turn it on. If you get video on the known good monitor then that means the original monitor is bad. If you don't get video on the know good working monitor then that means the computer has no video output and the computer would need to be troubleshooted.
Hi I have similar, I'm an electronics engineer and took mine apart only to find the power supply is very sick to the pint the pcb that converts all the signals probably has been damaged too, ie BIN FODDER.
Not very constructive but at least I know what is wrong - if I can get any constructive info i willl post it....
It needs the power supply board fixed. I have fixed several like this. It needs 5 or 6 capicitors and a 7.5v zener diode which is really easy to do if you know how to solder. If you dont know how to solder you need to take it to a repair man or buy a new one.
