Tv is dark

If your TV has already fully adjusted in brightness set up?, and there will be no good picture results?...try to adjust the "SCREEN-Screw" at the flyback slowly. If the picture still dark'?. the picture tube has need to rejuvenate.

Try going to your menu or input select and you should see a scale to darken or lighten input. The remote should have a button on it to let you get to main menu.

The set does use a lamp for a light source and average life is 2 years or 2000 hours---many lamps before they actually fail get to be darker.

adjust the color go to the menu and change the color meter to darker or lighter and your welcome

To adjust the default lighter/darker setting

1. On the LaserJet 3015, press MENU/ENTER.

2. Use the < or the > button to select Copy setup, and then press MENU/ENTER.

3. Use the < or the > button to select Def. Light/Dark, and then press MENU/ENTER.

4. Use the < or the > button to adjust the setting. Move the slider to the left to make all of the

copies lighter than the original, or move the slider to the right to make all of the copies

darker than the original.
5. Press MENU/ENTER to save the selection.

Page 48 of the User Guide has instructions for adjusting the light/dark setting during a copy job.

Also see the Troubleshooting section of the User Guide for other possible reasons for light/faded copies.

If your copies continue to come out too light, you may need to clean the insert a new toner cartridge or change brands of toner. I tried several "generic" toner cartridges and refills, but my prints and copies were always faded or streaky. After going back to genuine HP cartridges, I haven't had any print quality problems.

In many many cases this is an indication of a failing picture tube. The gun assembly in the neck of the picture tube is shorting. There is a fix, but this is surely last resort and the final cure may not provide a fix. Picture tube rejuvenation is not always successful. I would certainly opt for a new TV. Thanks for asking, and show a few hands of support!

This sounds like low screen voltage(A1)try adjusting the a1 voltage bottom control on flyback transformer if you have a voltmeter, voltage on crt base possible market screen or A1 shoud be beteen 350/500 volts when making adjustment remember to take into account current taken by meter If voaltage will not adjust flyback transformer will have to replaced

there so many things which can cause that to happen an these are thwe following,
i a tube has to be tested
ii a line transformer
iii vedio amplifier
this tests can be done in w/shop where other tvs are of the same.

have you tryed adjusting the picture in the menu section! this may help!! or on back of tv is adjusters those may help as well.

mkbowen,

whats the brand name of your TV?

also try this, facing the front of your screen. locate a button indicating " menu" and click it.
once the menu button been activated there would be a display box indicating "AUDIO" "VIDEO" "TUNNING" or in some cases the screen will indicate one by one setting every time you press the "menu" button. If you'll able to find a display indicating "video" higlight the said icon and navigate throught it until you see the control for brightness. you can navigate the icon by pressing +/- channel button and to change the value of selected item you need to press +/- volume button of the screen.

cheers ,
