This sounds more like a Lcd fault than bulb after such a short time after bulb replacement ,however I did have this come up once and the customer had kept his unit in a cold place then took it out to use hence due to the heat from the lamp Condensation dulled the mirrors .After they warmed up all was ok untill the next time solution I told him to store it somewhere warm .. havent heard from him since except for his stereo repair , and you don't want to know what the fur substance in that turned out to be lol
if it is an lcd fault you may find a replacement of ebay a cheaper solution ... Regards Vortash

ps and the beauty of that is you could sell your old unit minus the bulb as spares and repair and get some of your money back you just spent on the replacement .. lol

HOW TO SET BRIGHTNESS OF THE SCREEN?


Hi,

Dear User...

You can adjust the brightness and contrast of your monitor to improve the readability of text and to make digital pictures appear more like they'll look when printed.

To improve the results when adjusting the brightness and contrast settings for your display, use Display Color Calibration. (Display Color Calibration helps you adjust these color settings and others.) For more information about calibrating your display color in Windows, see Calibrate your display.

The way you adjust brightness and contrast varies and depends on your specific display.

Brightness and contrast buttons on the front of the monitor. Some monitors have brightness and contrast controls on the front and use the standard symbols shown in the following image.


On-screen menu. You can change the brightness and contrast settings for some displays by using an on-screen menu, and then setting the brightness and contrast in the resulting menu. Many times, you can view the on-screen menu by pressing a button-possibly labeled Menu-on the front of the monitor.



Thanks....

Going dim, POS NCR 7452 cash register 9" vga mono.


bcollier696, You did not state how many hours of use this small screen monitor has on it!! You may need to replace the CRT if it has been in use for a long time. Can you approximate the total "ON" time of said unit? Is it >10k hrs. Multiply hrs/day x 300 days x yrs of use. If u come up with 15k hrs or more replace the unit with an LCD if possible.

Best settings for moderate to low light viewing?


Using your remote, click the "video" button (mid area, Right hand side) and adjust the brightness, contrast, etc., to your liking. Only you know what you like. If your picture can be "plenty bright enough"...then just make the necessary adjusts to whatever looks best to you. If your picture is "very dim" no matter what the video settings are, you need a complete cleaning of all lens, mirrors, and screen...and possibly a new lamp.

Picture is very dim


there is a problem in the flyback section of the tv set. the fly back has two knobs, one for screen and the other for focus. use the screen knob to adjust the brighness. if it did not help, either check the capacitors around the flyback or change the fly back with a new one. good luck
