Screen too dark even with all brightness settings set to max

The picture on my tv is very dark even with all brightness settings set to max. this problem makes playing videogames very hard because in areas where the lights are dim, it is pitch-black, but on other tvs you can see perfectally. why is my JVC doing this?

Picture is very dim

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

Brightness of picture

If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.

Dark picture (HELP)

Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.
