LCD screen will not change contrast

All of a sudden, the numbers on the LCD screen are very, very pale. I have tried looking in the manual and online both, and I've read that you need to press the 2nd key and the up botton in order to make it darker, and I have tried this and there is no change. I have also changed the batteries, and there was no change again. What could this be? Thank you!

Try replacing both the AAA batteries and the back-up batteries. This should probably fix the problem.

My Envision LCD Monitor screens turns gray once its power on. I have tried changing contrast will not work.

When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Good luck!

Vaio LCD problem

Periods.......Nice little items because they denote the End of a sentence.
See how this works?

"I have a vgn cs36gj, I was working with it, suddenly the LCD became pale black, I connected it to external monitor and it has a picture, sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

Now you try it.........

"I have a vgn cs36gj. I was working with it, suddenly the LCD became pale black.
I connected it to external monitor and it has a picture."

Okay, I got that part.........

"sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

WHICH LCD?
Laptop LCD?
External monitor LCD?
Man on the moon LCD?

1) If the external monitor LCD goes 'pale black', the problem is the graphics chipset.
This I do not believe

2) If the laptop LCD goes pale black, this I believe.

Post back in a Comment.

My lcd backlight is very pale, how can I encence the brightness??

Reading your user manual on page 12, bullet 9 you will find the method of changing the contrast of the display. There is no brightness adjustment possible, however the contrast DRASTICALLY affects the readability of the display.

The picture on my Vizio 42" flat screen suddenly shifted to a whitish pale color with ghostly looking images that look like negative film.

This is the fix for the Main board repair :
Locate IC 32 small 8 pin surface mount near top of Main Board and remove. Short pin 2 to pin 5. (pin 5 through 8 are together and pin 2 and 4 are together)
You will need a good TV Tech to do this for you.

GE Profile dryer-LCD panel flickers!

Look in your Use and Care book on how to change the screen contrast. It has two settings. If changing the contrast setting doesn't do it, you need a new display board. GE Parts 1-800-626-2002

Re-Sized Photos are Grainy

Hi,

This camera takes pictures with a Ppi of 72. That is why the pictures look huge on the screen. To get good quality prints you need to have at least 200 ppi, or even better, 300 ppi.

Or, the contrast of the pictures may be to low. I have an FZ7 too, and I always tweak the contrast and color saturation before outputting.
----------------------------------------------------------------------------
1. images straight from the FZ7 are generally low in contrast.

2. Pictures that are low in contrast might not look too bad on screen, but when they are printed they will look slightly greyish.

3. Low ppi pictures look fuzzy in print.

Maybe you can post a sample original picture??
