    I have the same problem. I tried replacing the bulb but that didn't help make the picture any brighter.

This happened to my 44nhm84.  The problem turned out to be the light tunnel, which is an arrangement of four little mirrors mounted between the lamp and the color wheel inside the light engine.  One of the mirrors had come loose and was blocking the light transmission pathway.  I used a little dab of glue to hold the mirror in position, and the problem was fixed.
I've read about other reports of problems with the light tunnel, but usually they say that only one side of the picture is dim.  I think it depends on which end of the light tunnel gets blocked.  If the end towards the condenser lens is blocked, then the blockage will be imaged on the screen.  If the end towards the lamp bulb is blocked, the problem is well out of the focal plane of the lens, so a general dimming is the result.

You will probably find, cahnging the lamp and resetting the timer will fix this problem.
Contact Toshiba for more information if you need to.

Tv very dark what can i do brightness tured up full still very dark


First check this points:
1. How old is your TV.
2. How many times you have change your lamp.
3. Any sort of weird sounds on the back of the TV.

If you are having problems whit the brightness of your TV or you are seeing a dimmer picture, you might have to change your lamp or your ballast, if it comes to a point where you do not see any image at all but you still hear a sound, then its definitely the lamp, if you dont see image or hear any sound, you might have problems with your ballast, also when your ballast begins to run out the picture can get dimmer due to it sending less amount of voltage to the lamp, i suggest to check with a tech to confirm it, or get a second opinion. Hope i could be of assistance.

My picture is foggy is there coolant that needs to be replaced in a toshiba 44nhm84


This type of TV doesn't use coolant. I would suggest to clean the mirror that reflects the image from the optical engine to the screen before replacing the lamp.
Let me know if you need further assistance.

Shadow down right side of screen on a toshiba 44NHM84 44" DLP television


shadows at the bottom of the screen sound like moisture that was "wicked up" between the screen layers and dryed out leaving a stain. DO NOT get these screens wet, use nothing but a damp soft cloth; just a few drops of water running down the screen can cause a fairly large stain. Some people have suggested that they may be professionally cleaned, but the risk of damage is too great on the user level.
