Led tv no picture


Sounds like fluorescent tube has gone, but you say this is LED? Newer tvs are LED. What you have, may be LCD, in which fluorescent tubes were used. You have no recourse.

How do i adjust the magic focus?


  • Press "Menu" on the remote select the "Magic Focus" option in the Video menu or press the "Magic Focus" button on the front panel to adjust the convergence of the three picture tubes that create the proper color for the picture. Pressing the button on the TV initiates the automatic adjustment, and accessing the feature through the Video menu allows you to choose automatic or manual adjustment, though the "Automatic" setting must be selected for the button on the front of the TV to begin the process.

    How do you access the convergence calibration menu on a RCA P52926 Rear Projection TV


    Hello
    To access the convergence calibration:

    Press the MENU button on the remote.

    2. Press 3 to select the Screen option.

    3. Press 4 to select the Adjust Projection TV option.

    4. Press 4 to select the Advanced Convergence option (the
    Advanced Convergence screen appears).

    The green pattern is fixed. The red and blue patterns are adjusted to

    the green pattern. The Red Convergence appears first by default.

    5. Colored cross-hairs show the current adjustment position on the

    grid. To move the cross-hairs to a different position, use the

    CH+/- buttons on the remote to move the cross-hair highlight up

    and down, and the VOL+/- buttons to move it right and left.

    6. Use the arrow buttons to adjust the red pattern. Each press of

    the arrow button makes a slight adjustment from the center of

    the cross-hairs - you can press and hold the desired arrow

    button to make a faster adjustment, and then make fine

    adjustments with single presses of the arrow button.

    7. Press the INFO button to switch to Blue convergence and follow

    the steps above to adjust the blue pattern.

    8. Press OK to exit. You will be asked if you want to save the
    adjustments

    Yes Saves adjustments.

    No Returns to the Advanced Convergence screen allowing

    further adjustments.
    Clear Exits screen without making any changes

    Note: Before you use the advanced convergence feature, you must
    complete the previous steps to align the tubes

    Our tv has been getting darker and darker - we've tried to adjust brightness in menu and have it set to far right but its still too dark. Is there another adjustment to brighten the picture other than...


    In many many cases this is an indication of a failing picture tube. The gun assembly in the neck of the picture tube is shorting. There is a fix, but this is surely last resort and the final cure may not provide a fix. Picture tube rejuvenation is not always successful. I would certainly opt for a new TV. Thanks for asking, and show a few hands of support!

    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.

    Hitachi 43FDX15B distorted picture. The top of screen displays a half circle cirle and the image is distorted within the half circle. The same at the bottom of the screen. The middle of the screen is fine....


    Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

    Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

    Common Symptoms include....
    • Screen looks 3D
    • Colors don't line up
    • One or more colors can't be adjusted when using the convergence menu.
    • Screen is bowed or warped.
    • TV shuts off after powering on - TV may also make a chirping noise.
    Here are some photos of convergence problems.

    f0add3d.jpg


    Here is a quick test....

    Using your original remote go-to the settings menu then goto the convergence section.

    Try to adjust the red and then the blue convergence.

    You should be able to move RED and BLUE in all directions - up, down, left, and right.

    If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

    Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

    93a1209.pngCONVERGENCE SOLUTION

    You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
    This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

    The picture started to get blurry, after being turned on for 10 minutes would clear up, now just stays blurry and almost no picture at all.


    Hi

    Thanks for using FixYa. To reset the picture you’ll need to reset all the Video menu options to their original factory setting for which you’ll need to follow this step-by-step procedure---

    Press the Menu button and then use up or down arrow button to select the Video menu. Now press the right arrow button and then use up or down arrow button to select Video Reset then press the right arrow button to reset the Video menu options to original values.

    If still the problem persists, then you’ll need to check for local interference such as an electrical appliance or power tool and also check the antenna. If required change the direction of the antenna.

    To resolve the issue of Blurry Screen, first check whether all the cables from your dish network are fine and connected firmly. If yes then you'll need to pull off the front of the TV, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. So we are doing real small adjustments. Turn the color off on the TV and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.

    And, if it doesn't resolve your issue then it is an intermittent blue picture tube, a bad blue driver transistor on the CRT board, a bad connection on the blue CRT board, or a problem in the RGB coming from the video jungle IC. A set this age, most likely will run about 300-500 bucks to have this problem fixed, unless it is the picture tube.

    Please do accept the solution if the issue is resolved or else revert for further assistance.


    Thanks

    Too much yellow in picture


    The problem with the set is that the blue gun has gone weak, and not emitting at par with red and green guns in your picture tube. Turn of the blue screen and get the grainy display on the screen (detach the cable) and enter into service mode to fine tune until you get a perfect or black and white grain pattern.
