SOURCE: Dark screen since new

Wow only 10 then major work, hum. First if pic is:Split screen picture with one half darker than the other half. "Deep Field Imager" is set to the demo mode, press the "video" button repeatedly to cycle through the video settings until Deep Field Imager is accessed and then change the setting from demo to "on" or "off" depending on preference. Also u can try:1. Dark blue raster with faint movement in the background, suspect the FMT PCB part # 934C153001 . Also1. May be intermittent. Remove and reseat the DVI cable between the Chassis and Optical engine 2. Removing and reseating the DVI cable does not resolve, replace the Optical Engine part # 938P015020 Hope this helps Tom!!

SOURCE: strange phosphorous effect

The problem either lies in the Scaler PWB or in the lcd panel itself. How old is the unit?

SOURCE: Hitachi 50V710 The picture is dim,

I've seen this in two scenarios.


First: The housing of the bulb is dirty (the lens the bulb lights onto) and the internal screen is dirty also.


The second: The bulb is wired reversely of the proper way to wire it. This will light the bulb, but will not light as bright as when it is wired correctly!


Thank you and please rate!

SOURCE: the screen on my Audiovox FP1510 has gone dark

Most likely you have a bad INVERTER module, this module supplies high voltage to the baklight assemble which is likely why you can only see a very dim display on your LCD TV. The inverters are relatively cheap. Hope this helps ! Good luck..

SOURCE: Mitsubishi WD- 73737 73 in. Screen if dim or dark. Changed contrast, brightness, and restored default settings but that didn't work. Help?

I am not sure about your model but a call to Mitsubishi to ask if the set has one or two mirrors would offer a possible explanation---the ones with two mirrors have a small one at the bottom--it gets coated with dust and brightness drops up to 75 percent----other possible reason is the lamp may be nearing the end of its life.

I would have Mitsubishi look to see if this model uses the two mirrors--if that is the case cleaning will cure this--if you find it has two mirrors I can tell you what is involved--on Vacation but do look here--let me know what you find.

Dim screen acer 5100-3019


Try going into power option settings and taking the brightness to the max there. Start, control panel, power options, then you should see a setting for battery and for plugin. Hope this helps.

Dim display on laptop LCD screen


The part you need is called a CCFL Backlight. Basically, there are lights in the screen that back-light/illuminate the display. Over time it burns out and you are left with a dim and completely dull display. These are a pain to replace and expensive when bought from the manufacturer. But this site has a break down with dis-assembly instructions...if you want to try it.

I have an HP Pavilion DV2000 The screen suddenly went black The drive was removed and scanned for viruses then replaced When the system was restarted the screen seems to work but only very dimly....


sure the screen is bad.
internal.
the DV2000 runs CCFL back lamps,
all go dim with age, and yellow. all do.
so can be only this.
bad CCFL lamps or the CCFL inverter driving it.
vast PCs like this are in the recycle centers. now.
endless.....

The screen on my Audiovox FP1510 has gone dark


Yes, there are 4 backlight lamps but it seems you have a problem with the circuit, called inverter, that controls those lamps. m@nt

GPS screen no longer lights up


If you can't control it with the controls, then most likely the backlight has died. The entire LCD display will need to be replaced as the backlight is integrated into the LCD display.

Squares visible in bright colors


Turn down the contrast to about 55-65% of maximum. Also turn down sharpness to about 10-20% of maximum.

If ther is a Contrast Plus option, or digital contrast, turn to minimum or off. (Dependant on TV)

This is a common side effect with digital television.
