Question about JVC AV-56WP30 56" Rear Projection Television

4 Answers

Lamp issues there is green horizontal lines that appear to be convergance issues. When I cover the Green lamp lense cover, the lines disappear but of coarse the picture is more red. Could this be a bulb or maybe a board issue. Is the G, out of the RGB have any special relevance? I appreciate any advice.

Re: lamp issues

Actually man... you need to find the flyback transformer for the green tube, and adjust the raster on the green screen down a notch. most likely you are dealing with an issue where the coil inside the flyback transformer to your green CRT has a bad spot on it and the coil wiper is setting on top of it causing the resistance value to drop on the overall coil. Find the flyback transformer for the green CRT, adjust the screen coil slowly until the lines fade away. Do not adjust the focus coil. Screen coil is usaully above the focus coil.

Re: lamp issues

No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck

SOURCE: red tube is projecting wide (convergence)

You need to replace the convergence IC's

SOURCE: Convergence issue?

This still could be the convergence . This will should be repaired by a tech if you do not know how to repair . Around $200 - $300 if you could get it to him or more if he has to make a service call . Call around for the best price as alot of shops vary in there charges. On this problem if it is the convergence make sure they will use the original IC's and not the cheap replacements as they do not hold up as long . Good luck

SOURCE: the red, green and blue colors do not line up correctly

This set is fairly easy to fix for this trouble. A AV48p30 usually takes me about 40 minutes to fix for this problem.

It uses two of the STK-392-110 convergence chips. The repair involves two things--getting at the chips (easy) and being able to unsolder them and replace them.

You can buy almost everything you will need on Ebay for under 30 dollars (I can tell you who to look for there)

Most shops are going to get 300 or more for this kind of repair so if you or someone you know can do it you can save a lot of money.

I can tell you how to get at the chips and also everything you will need to do the repair.

If you want the detailed instructions let me know and I will post them here for you.

It has tripple vision and looks like a bow tie.

hi, sounds like a convergence issue. try this...
  • Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.

  • Enter the menu on your TV. Use the remote control and bring up the menu.
  • Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  • Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  • Press "Enter." A crosshair pattern will appear on your screen.
  • Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.
  • Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.
  • Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.
  • Repeat these steps for all colors.

  • good luck!

    I have an rca model hd52w67 tv and there is a problem with the picture. the picture has a red and green picture that don't allign by about an inch. I think it is in the picture guns but i cant find a...

    Do not align the guns! they are located facing up toward the mirror; they are picture tubes! covered with big glass lenses! heavy!
    instead look for a red/green/blue adjustment knob on the set's front; the buttons should say: convergence or, crosshatch push the crosshatch button: once you have three vertical lines crossing three horizontal lines; just merge them using the other R/G/B knobs untill you have one white vertical line and, one horizontal line crossing in the center of the screen.
    (you may have to find the controls on the remote using "setup")

    I have a KF-42E200A Sony Bravia LCD tv. Recently we had to replace the lamp. Since then a horizontal line appeared at the top of the screen and it has grown to about 3 inches now. The picture itself is...

    The lenses in the TV are more than likely misaligned due to heat from lamp. The heat can cause the lenses to move and the red shaded horizontal line appears over time because the lenses fall out of alignment.

    You just need to have the lenses realigned and the red shading will go away.

    1st set Brightness and Contrast settings to 50% at tv menu.
    You need to cover 2 CRTs with any thing like thick paper while adjusting 3rd CRT.
    For example, lets adjust Red CRT G2 volts, Select audio-video input 1 and cover green and blue lens with paper note-book and rotate Screen control up to level where you see retrace lines on projection screen, now decrease screen volts (G2) so retrace lines disappear and projection screen should be blank.
    Now do same process with green and blue adjustment while other lenses should be covered.
    Im not sure I conveyed it to you properly or not because English is not my 1st language.
    Thank you.

    Converging green?

    jaymz, you can`t move the green, the green tube is always mounted in the middle and is not adjustable from the convergence menu. red & blue should be converged one at a time on top of the green, once you have accomplished this the crosshatch grid will be white and that means your done :)

    I am told my Hitachi 61SDX01B (UltraVision/Ultrascan) has "Green Geometry"

    Sounds like a convergence promblem.

    Here are some of the most common symptoms of a convergence problem.

    Screen looks 3D
    One or more colors can't be adjusted when using the convergence menu.
    Screen is bowed in or warped.

    Here is a quick test....

    Using your original remote go-to the tv settings then goto the convergence or magic focus section.

    Try to adjust the convergence.

    You should be able to move them up, down, left, and right.

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

    Its a fairly easy fix on the Hitachi sets.

    You can get a repair kit that includes all the parts from The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
    Everything you need to fix it yourself.

    Strange series of bowed lines in the picture

    Nope, not dust on the lens, but you have two IC's in the convergence correction circuit that have to be replaced. you shouls get the service manual for this set, as well as go to to find the download but also go to www.mcmelectronics to get the STK convergence IC's. If you have no solid state printed circuit board repair experience, I highly advise you to call in a pro to assist you in this repair. Good Luck
