Question about Philips 190B6CB/27 19" LCD

1 Answer

Philips 190G -> http://www.cnet.com.au/i/r/2006/desktops/monitors/22139625/Philips_190G6FB-97_c.jpg

The monitor randomly lost the picture. The lamps are green and everything seems fine except the actuall picture. What can it depend on?
The monitor is relative new, think it's 1 year old.

The picture disappeared and now the picture is all black...

thanks / Dennis (dempa887@hotmail.com

    My phillips 190g is not quite 3 years old and the sceen is black all of the time no matter what input method I use.I'm very dissapionted with the life span off this well known top brand unit.I thought it should last at least 5 years or so!

    I have the exact same problem, the screen went black. I actually by accident turned on a headlamp and when pointing at the monitorscreen I can weakly see my desktop... I am now writing this with help from my headlamp on my otherwise black screen. Everything else seems to function correctly... what to do?

    I have the same problem, one day my screen was fine and then the next it stopped working everything else works bar the screen it's just black. is there anything to fix this or is the screen blown?

    When I power up the monitor you get a flash of the full PC screen for about 1 second and then the screen goes black. I am guessing this is a problem with the backlight.
    Has anyone resolved this or a similar problem?

My solution:
Open the monitor. Take off the mainboard. There´s a supply board for the backlight under it.
Replace the two purple capacitors (150uF/25V). These are from a bad batch.

Also replace fuse F1 (lightbrown SMD-component) on the bottom of that board (near the long side).
It has blown as a result of the bad capacitors.

In my case the values were dropped to 25 uF. And the internal resistance (R) was more than 2 ohms.

That´s it. Hope it helped you.

Not likely to be the lamp (but not 100% sure), more likely to have bad DC caps problem.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.
