I think you answered your own question. You have a rear projection television. It sounds like the lamp is not functioning correctly.
All projection lamps have a recommended life measured in hours. I checked the web and this model appears to be about 3 or 4 years old. from 2005 or so.
The lamp in my Samsung is rated at 3000 to 5000 hours, I had 12,800 when the service Tech was in changing another part.
3 or 4 years running one lamp is a good run. This is why DLP has lost favor for table top sets, Most are LCD or Plasma now.
Check you TV for it's lamp model and them shop around allot. Lamps are not cheap however some suppliers offer much better pricing that others. Care should be taken to make sure you order and purchase real replacement lamp and not a clone / compatible model. Original parts should produce the picture you are expecting

A dark washed out picture in older sets is normally
caused by all three of the pic tube being weak. and
it's not cost effective to replace/repair. but that
would depend on how old it is, and what model .Some
Toshiba Projection sets wear built well.

I don't know how much help that was?

I have a lg 32" tv and have connected everything

Dark picture means you have low brightness on the screen. Please increase the brightness. Also try increasing the back light intensity.

Dark Pictures

try reseting the camera back to default settings, there should be a function for that in the menus or a small reset hole somewhere in the camera.

How do i adjust the brightness on my HP6710b. I normally do it with fn key but that aint working?

Generally, the function key only works when you are running on battery. you can adjust the brightness at the power options. Go to start, control panel, power options, edit plan settings. Move the slider to adjust your brightness.

At start up my viewsonic va1912wb display blinks several times then i can see the picture but it is dark almost unreadable. Today it went darker than yesterday. HELP!

If it is dark due to brightness adjustment, get that adjusted. Usually when you adjust the brightness by pressing the menu button, the menu screen would not be dark. If everything is dark dark dark and you can only see some display but in very pitch darkness, then your monitor is a goner, backlit for the monitor is dead, and your monitor will need to be replaced. You can fix the backlit tubing, however it is risky, and expensive, and would cost less if you bought a replacement.

Is there a way to access the tint function on the Apex4088? It is not accessable when we go into the picture setup menu. It appears to be locked.

Hello

The Tint function can be accesed by the following steps.

The PICTURE menu offers options to enhance and refine the picture displayed on your TV based on ambient room light and personal preferences. Adjustment options include contrast, brightness, color, sharpness and color temperature

Press the MENU button on the remote control. Navigate using t u arrow buttons to select PICTURE. Press the down q arrow button to highlight PICTURE MODE, then press the u arrow button to select your viewing preference from 4 factory options:
STANDARD > DYNAMIC > MOVIE > PERSONAL. The STANDARD setting is recommended for most viewing environments. Depending on the ambient light level in the room, you may find one of the other options more pleasing.

To make more critical adjustments based on your own preferences in PERSONAL:

• Use down q arrow button to highlight Contrast. Navigate using the
t u arrow buttons to increase or decrease contrast intensity.
• Use down q arrow button to highlight Brightness. Navigate using the t u arrow buttons to increase or decrease overall brightness.
• Use down q arrow button to highlight Color. Navigate using the
t u arrow buttons to increase or decrease color intensity.
• Use down q arrow button to highlight Tint. Navigate using the
t u arrow buttons to adjust colors toward green or reddish tint.
• Use down q arrow button to highlight Sharpness. Navigate using the t u arrow buttons to soften or view crisper edges in the picture.
• Use down q arrow button to highlight Color Temperature. Navigate using the t u arrow buttons to select COOL (more bluish tone), NORMAL or WARM. The default setting is NORMAL. WARM mode will provide color that is calibrated to D6500° Kelvin, the standard color that broadcast stations and the Motion Picture industry consider as the most accurate to view programming.
Note: When adjustments are completed, you may select another menu by pressing the Menu button.
OK

How to adjust brightness

You don't say anything about the brand, but most have a menu or setup button on the remote (and TV) which give an on-screen display of functions available. You should see one for picture adjustments. Perhaps the projection bulb is getting old and dim. This is another possibility.

Dark screen

if the picture is REALLY dark, like you can just barely see it in a lit room, then the backlight might not be lit. LCD TVshave backlight that shines through the LCD screen which allows you to see the picture.

If it's not the backlight then it would be the brightness/contrast settings that need to be adjusted. If the picture used to be normal and all of a sudden went dark, verify the backlight. Normally you can look through the slots on the top of the set and determine if the backlight is on. If you can see a bright light through any of the slots, the backlight is probably OK... go after the brightness/contrast settings.
