Question about JVC AV-48WP30 48" Rear Projection Television

1 Answer

Red horizontal lines

We have a JVC AV48WP30 and when we turned it on yesterday there were red lines that seemed to start on the left and look as if they were bing "pulled" across the screen to the right (looking at the tv) side. We bought this used so I don't have a manual. Please help. Also seems to have red ghosts now.

    Do you have an estimate on replacement cost, the TV repairman told me $170 X 3 (for each color)

Hi,
Misaligned red lines in your TV is due to failure of Convergence Out ICs and requires replacement.

Let me know if you are familiar with TV repair to provide you part number info OR call local TV tech to fix the TV.
Thanks.

I CANT ADJUST THE RED VERTICAL LINES ON MY JVC REAR PROJECTION TV. i HAVE DONE CONVERGENCE AND MANUALLY ADJUSTED THE RED LINES HORIZONTALLY, BUT NO LUCK WHAT CONTROLS TO USE VERTICALLY


If it will not adjust up or down or left and right the convergence chips need to be replaced.

See attached photos of board that is in your set:

The red tube is not acting right. When you go to convergence, the red lines are not straight. They are concave, I think is how you would describe it.


You need to install a convergence repair kit. You can get the AV48WP30 convergence repair kit at www.tvrepairworld.com the kit contains the parts and the Cd with detailed photos with instructions.

Screen is red with lines when channel is changed


If its a kp-51hw40 : go to an unused video input and look at the screen---if it is redish in the background with curved faint trace lines you have one of two things wrong; First: the red "screen" control may be set too high. Second: you may have a problem with the RED picture tube.


To try to adjust the RED screen down you have to remove the entire front grill plate on the front of the TV(some have screws on the back on either side that have to be removed---and then you should be able to pop it out. Behind it there is a masonite inspection plate held in with screws----Once you have that off look for a SMALL SQUARE BLACK PLASTIC BLOCK; it has 6 black adjustable controls---you have to use a flashlight and look carefully---one row left to right will be marked FOCUS--DON'T TOUCH THOSE---THE OTHER ROW left to right will be marked SCREEN; if you look carefully you will see marked by each r (red) g (Green) b (blue)
you want to locate the RED SCREEN CONTROL.

WITH the set still on a blank video input where you can see it clearly turn the RED Screen Control to the left until the lines and red tint go away---do this slowly and make sure you are adjusting the RED screen--not the FOCUS.


IF this has been helpful give me a vote here as I do this for free; yesterday I adjusted one of these in a home that was blue with the faint lines---about 15 minute job for me.

Yes the red tube is shorted. I will post a link to the site where I work as they have an entire AV48WP30 with a bad tuner they are selling parts off of including the Tubes. they also provide free info on how to switch out the tubes as a unit which is a fairly easy job. Heres the link.
