You can try this, from the rear with the back removed locate (hard to miss) the three large round black lens, they are on top of the three picture tubes the set uses and are your light source, if you can reach them clean them with a lens cloth or a paper towel with glass cleaner sprayed on the towel.

over time they get dusty and the picture will get dull and dimmer.

I have a Samsung 55in curved TV. It has auto dimming. In the evening with the lights out it dims to where it is difficult to see the picture. Can I get rid of the auto dimming?


If the brightness on your TV changes automatically (randomly dims and brightens), you may need to adjust the:
  • Eco Sensor function.
  • - And / Or -
    • Energy Saving function.
    The Eco Sensor and Energy Saving functions adjust the brightness of the TV to reduce power consumption.
    • When you set the Energy Saving function to Auto, the TV changes its brightness automatically depending on what you are watching on the TV.
    • When you set the Eco Sensor to On, the TV changes its brightness automatically depending on the brightness of the room.

Sony LCD TV has Dark Picture


Hi there,

the problem is not the lamp.

This model has a set of two backlight lamps, and it is practically impossible that both lamps go faulty at the same time.

When the backlight lap in an LCD TV goes off in this way, the faulty part is always the backlight inverter, that is the high voltage board powering the lamp.

In your case you have to get the TV inverter booard replaced.

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

Toshiba 36A42 TV. Dim Picture


Check the "screen" control on the flyback (lower knob) its easy to hit moving a board around. Try to adjust back to its original setting. Look for where the dust is, it should be on top. Or any marks might help. Other wise adjust slowly, back off if any retrace lines appear, with user settings at there normal settings.
