Hello, I have seen that the VX922 has a problem with the PS capacitors when the green led starts blinking. I have a VX922 but it doesn't power any led. I checked the power supply and I found two 470uF capacitors blown (dommed). I replaced them bud still no life signals. I decided to replace two more 330uF capacitors and one more of 10uF but still nothing.
I have seen that some of these power supplies have more capacitors and more regulation diodes. Mine has only the electrolitic capacitors I have replaced and one more big of 100uF 400V that is the only one I haven't replaced but is not blown.
I've checked the 12 volts and the 700VAC voltage and there is nothing.
My PS has also two heat sink one straight attached to a with a three pins IC? with the following info:
CET
5410Z
CEF04NG
I have no idea what is it and the board is a bit brown close to it so I suspect could be burnt. The other heat sink is "L" shaped and has a three pins Shotki diode? MBR10100CT close to two 470 uF capacitors I have replaced.
Any Idea of what is the first three pin component I mentioned?
There are diferent types of power supplies for this monitor?
Any sugestions of what I should replace?
I uploaded a picture of my PS:

- Hey I'm working again trying to repair my VX922, the good news is I have power, the green light is steady and I can see something on the screen when conected to a pc but now I have no Backlight :(
I conected the power supply and tried to meassure the 700VAC with my cheap multimeter but I have nothing...
Is there a problem if I change the pink and blue connectors of the backlights? I suppose thei don't have polarity but I'm not sure. I forgot the order but I tried several options but still no backlight.
Any sugestions?
