Hi there!
Depending on the age of the TV, it might be power supply related. Check Mains smoothing cap or others in the area. Video circuit is also a possibility. Tube would be the last option to look into depending on the age of the set, Good luck,JUS004

My youtube viteos are too dark! How can I make what I am viewing brighter and clearer?


It's impossible that JUST youtube videos you are watching are too dark.

You'll have to adjust the brightness settings on your monitor.

Jvc 27'' TV is too dark


There are two small holes on the rear side through which you can adjust focus and screen. Use a flash light and locate the two adjustable slots inside the holes. This part carries high voltage. Do not use a metal screwdriver to adjust. Put the TV facing a mirror so you can see how it works. Do not turn more than 1/8th of a turn. The focus control makes picture sharp or fuzzy. Screen control could change brightness. While watching the picture in the mirror, slightly adjust the screen control. Do not turn too much. If it doesn't work, then call a JVC authorized repair center.

My 61" hitachi rear proj has a very dark picture.


It sounds that lamp in TV is weak and not throwing enough light to bright the screen for good image.
How old is this TV and did you replaced its Lamp recently?
If lamp has not been replaced yet or in last 2-3 years, replace it.

Poor Picture Quality


Todd, In the user menue there has got to be adjustments for the brightness, contrast, sharpness,etc. I know there is no such thing as a simple tv anymore. On some sets if you do not have a remote control, you cannot make any adjustments. If you have one for this set and it works, trust me, the settings are in the on screen menue.
Hope this helps,

Screen is too dark


with a flashlight at the back of the set often times there is an adjustment you can make WITHOUT having to open the set!!!

look for a little hole in the back of the plastic cabinet labeled SCREEN then with a flat screwdriver holding only the plastic handle, insert it into the hole and SLOWLY rotate until the screen brightens up until it is watchable.

This is compensating for age in the picture tube. you may get a few day or a few more years! of a much better picture.

If you start seeing some thin lines on the screen then back off you have gone too far. Do this adjustment with the brightness and contrast controls on the menu turned up all the way.

it is also safe to play with the focus adjustment right next to the screen if thing seem a little blurry. you will need two people one to watch from a distance for best picture.

Dark scenes are impossible to see


This is a fundamental limit of Ti DLP. The part can not reproduce low grey scale, so low light film is dominated by artifacts. It helps to sit farther away from the screen. The color shift is caused by a factory tollerance on the color wheel, but there is no user adjustment for it.

Dark picture


Your problem could be the secondary anode cable or CRT socket, and you cannot fix this problem yourself unless you are a techie. It happens when your CRT base socket burns out, or when the pins are rusted or when the spark gap conducts to drain out the secondary anode voltage to the ground. It is better you call a service engineer.
