Hi kseguin

Your TV has internal problem @ video stage on the circuit
But you may try to apply resoldering on the circuit board near flyback and CRT circuit board.

Picture getting dark

My jvc 27" tv was so dark I could hardly see any night scenes, even with the bright all the way on. If you push the sleep button, let go, then hold down the video and display (together), the service menu will come on. Scroll down to #7 (too dark) and adjust the brightness there. Works immediately. Good luck.

Picture adjustment questions

*The brightness control setting determines how bright your picture will be. *The contrast control sets the gain of the video circuit. This determines the difference between dark and light scenes. Low contrast settings make the picture "hazy". High contrast settings make the picture more distinction between dark and light scenes. *The sharpness control determine the frequency response of the video circiut. High sharpness settings give better resolution but also shows more noise in your picture. Lower sharpness settings smoothe out the picture removing noise but also fine detail. It needs to be set for the best all around picture. *Picture Enhancement is pre-set adjustments which give you different picture qualities. You just select the one you like. Stargazer

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.

Toshiba 35A44 - Dark picture on all channels and DVD's

for this brightness problem actually came out from flyback, before you spend and waste your money, try to adjust at back of your tv first. But if you aren't an expert, better ask technician to do because that transformer supply a very high voltage....there's two adjustment point at flyback transformer, one point for focus and the other one for brightness! try first...
