This is another case of a capacitor problem with Hewlett Packard HP w1907 LCD monitor. When we turn the LCD monitor on, it would come on, but then immediately turn itself off. The LCD monitor model number is RK283AA.
Among the several LCD monitors we have worked on, this was the hardest to open. First, remove the stand. There are two tabs on the lower right and left of the monitor. Pry them open, and go all around the LCD monitor removing the plastic back shell from the front bezel.
Now you will notice the big problem. For whatever reason, instead of screws they used rivets to attach the metal cover to the power supply and the circuit boards. Rivets make everything harder. Remove four screws on the sides of the LCD panel.
The LCD panel will now separate from the main panel, however the ribbon cable is glued and we could not safely detach it from the LCD panel. However, if somebody else is holding the metal frame, the circuit board is visible now and can be unscrewed from the metal frame.
There was one capacitor that was bad. 1000 uF rated at 25 Volts. There isn’t a lot of clearance to de-solder the old capacitor and solder the new one. This is a good time to utilize obscene words. But it is do-able.
Put everything back together, and the LCD monitor is good to go.
