Picture Dark with brightness at maximum

No lamp as set has 3 picture tubes. You might be able to find the access on the net to the tech mode where sub bright etc can be adjusted.

Did problem happen instantly or gradually over a period of time?

The picture tends to get really dark during dark scenes. Can hardly see faces or details. Goes back to normal during brighter scenes.

the only thing you can do is adjust your brightness, contrast, sharpness controls. every station is different especially the sound is louder on some channels and lower on some.

Dark picture!

The Lamp it self, the Ballast, or the Power Supply that powers the Ballast. Even a combination of the Lamp and Power Supply is a common problem. If you have not replaced the Lamp since you have owned the set I would replace that first. The Lamp has about a 3000 to 5000 hour life span.
Hope this helps,

Adjusting darkness

Hi Angel,
Are you really sure , your set has video? How dark is it ? As if really nothing visible? Am, sure you can hear sounds. You can adjust the brightness + button to increase the brightness. But if nothing happens , you have problem with your TV set. The problem might be in the Video section. Please let an expert technician to check it. Please don't do it by yourself, it's risky.
Please send feedback whatever comes up. So we can help you further in the future.

Thanks,
Eriez

Dark picture

@ 6 years old I'd be willing to bet that it's time to replace the lamp. They lose brightness over time so that could be what the problem is.
