Re: Convert monitor ccfl to led

which way are you pointing the leds??
they should face towards the center of the panel - not forward.

Hi, they are facing towards the center of the panel.

Thanks.

It is just edge lit setup for typical monitor LCD panel.

Going back to the problem I have with the image, lots of brightness and little contrast, do you think it could be a gamma problem? If so, how can I confirm it? What tests should I do?


Thanks

I´m attaching the gamma chip. Could you let me know what to check out?
This chip IS NT68667 and mine is NT68672, I can´t find mine data sheet.

Based on the way the picture is show with straight shot:

And with angle shot (picture is not faded)

If the GAMMA Volatges are bad you will not see that kind of image on the screen like that when you look at in angle.
It's telling me that the sheets are not put back in correctly.

Hi, I mentioned the gamma because you suggested it on a prior post.
I just trust on your judgment and experience.

Latest news, the last time that I measured voltajes from the LCD panel connector, the 4 first pins measured 5V and now they are 2,58
What could it be? A short? Could be the connector the problem? And the screen looks white.

Thanks.

Re: Convert monitor ccfl to led

After looking at the angle shot of the screen again that is why I am still thinking that the sheets are not installed back in properly.
So now you are getting just white screen without any image any more?

Hi, I have check out twice the order of the sheets, they are OK.
And yes, I´m getting now white screen but,nothing related to the order of the sheets. It must be something different.
I believe because, as I told you on the last post, I checked out voltajes on the LCD panel and on the 3 first pins I get only 2,58 V. Before I got 5V.
I´m lost it is getting worse.

Thanks.
