Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Here are the settings:

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Sounds like the signal is probably too strong. The TV is not the problem.

Check the signal type. It may be set incorrectly. Change the channel. You may be on a blank channel. Check to see if the TV is tuned to channel 3 or 4 if you are watching a videotape. Check the TV/VCR button on the VCR is in the correct mode by pressing the TV/VCR button on your VCR.

White Noise Sound


Your problem is somewhere between the tuner and video detector circuit. The signal entering your TV carries: video,red color,and blue color as well as sychronizing pulses for color and horizontal and vertical deflection ( actually vertical sync. is derived from horizontal sync.) along with burst pulses to synchronize the color. After all these, the sound is an fm signal entwined with a pilot signal for stereo audio. WHAT a mess! After the audio passes through all this, it is detected and sent to the audio processor. If any frequency has drifted away from it's value then you loose the sound. SO... your problem could be in any of the tuned circuits or in the audio processor IC (chip). Any component changing value could creat this problem. Most likely the audio processor IC. You'd need to have the set checked out by a tech to find your problem. Stargazer
