Inverter problem where do I order an inverter board for an HP Pavilion f1503 flat (LCD) panel monitor (15 incehs monitor)

chect your bright and contrast controls if they are ok
replace the cold cathode tube power inverter circuit board; it's under the center bottom of your monitor screen

The part is a "ribbon cable" for an lcd monitor...ribbon made by Youngshin (AWM 2896 30V 80C VW-1).

2 ribbon cables for a hp pavilion f1503 LCD monitor (the two from the AD board to the TCP)

The LCD panel is made by HannStar (HSD150SX84).

Also, looking for other LCD parts, particularly:
the AD board for a Proview Pro-576 (I assume Sylvania PL-576 & Mag LT576s are similar); Board #: 200-100-AS576 Rev: B MV5-S2?
It uses a sampo inverter (QPWBGL8621DG) & a AU Optronics M150XN05 LCD.

This is a 15 inch LCD. and the inverters of these units go south often.
If the unit does not flicker and you do not have a lose of power, it will be the inverter.

You could have a faulty inverter board or a faulty CCFL lamp. The inverter supplies high voltage to the CCFL lamp and the CCFL lamp is a mini fluro tube.

here goes a link to the power cord

try resoldering the ciols on the power/inverter board.

can also check for cold solder on output transistors and coil.

If you can see the backlight ,white 2pin connectors connect to invertor pCB.Look around these two connectors you should see 2 brown/yellow/red transformers with a ferrite core.These are the inverter transformers , resolder all pins and power transistors around it.
That should solve your proble.
Please provide feedback and rate this solution.

THis is a problem of the invertor board.If you are technically able you need to disasseble the monitor and resolder components around the red or yellow inverter transformers.

With the computer on and the monitor connected, shine a flashlight at a slight angle on the screen and see if you can make out a picture. If you can, then it is most likely the ccfl inverter, if not possibly the power supply of the monitor.

Check the cable wiring make sure all is plugged up right, If you have rebooted and it comes on ok than its the power cord. Remove and re-plug again
