Inverter board

here is a link to the manual that should give you a diagram - http://dlsvr03.asus.com/pub/ASUS/mb/sock478/p4bgl-mx/e1339_p4bgl-mx.pdf - hope this solves your problem.

If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address.
Here are the symptoms...
Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.
Hope this helps,

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

you need to check first the power supply board whether the output supply 12-24vdc for the inverter board is stable and not flactuating..you can measure the output voltage with a multitester..you get a voltage output of 12-24 with the inverter board is connected or loaded to the system.be carefull of the high voltage at the inverter board..once the output is stable replace the inverter board or you can measure the output of the inverter be very carefull..the output range upto 500vac.be carefull..if the high voltage is stable replace the lamps...tnx and good luck..
