LP2407 No Picture after replacing Caps

[tractor698]

Hello All,

I have replace all the caps in the monitor with Panasonic or Nichicon caps:

C618, C609, C501, C605, C611, C613, C601, C615, C506, C506, C227, C223, C619, C334, C505, C1, C3, C904, C901, C912, C902, C928, C929, C501, C608, C609, C611, C605, C615, C601, C613, C508, C334, C619, C223, C227, C505

The monitor is connected to a running comuter with and output signal.

When the monitor boots up the Gatway logo appears no blue light and no touch screen function.
Then the monitor goes black.

I need help into what to look for now.

Any suggestion?

Thanks in advance.

Connect the button cable.

The first time I plugged it in after replacing the caps the Logo & the menu on the right side appeared.

Now only the Logo appears and no menu.

Yes the cable is connected.

Any suggestion on what to look for?

Check for an image with a flashlight. If the power LED is off, possibly the processor is shutting it down rather than "two seconds to black" due to inverter or CCFL problems. But the power light should come on for a little while at startup.

When it is turn one the Gateway chimes then Gateway logo then 20 sec into the power up of it the AUCUN signal with RGB appears then goes completely black. Nothing no light just black.
