Red shadows in 48" JVC rear projection


Well you better be pretty handy with a soldering iron. The convergence output IC's need to be replaced. These are large plastic pack IC's with 18 or so pins that are soldered on the underside of the circuit board. These IC's are mounted to large metal heat sinks.

Red horizontal lines


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.

Green tint on Samsung Television


Hi sbatsch,

Not to worry - this problem is very common with projection TVs and is easily fixed:

The reason for the green shadows (and the resulting wrong colors) is that the three color tubes (red, green, and blue - the three colors of light that combine to form all the other colors) are not lined up exactly - this lining up is known as "convergence." You can fix convergence automatically or, if it doesn't work to your satisfaction, manually. Here's how:

Automatically:
1) Press MENU.
2) Go down to CONVERGENCE (using the up and down arrows)
3) Select it (usually with the left or right arrow)
4) Go down to AUTO and select it - the process should take about a minute.

If this doesn't work, then try manually:
1) MENU
2) CONVERGENCE (as above)
3) Select MANUAL
4) Using the number keys, SELECT, and the arrow keys, adjust the alignment of the different color crosses - the goal is to make them appear white (meaning that the red, blue, and green are exactly aligned on top of one another).

Here's a link to the JVC user manual that will explain the manual convergence adjustment in more detail.

I hope this helps - please let me know if I can be of any further assistance.

JVC 48 in rear


Probably the projection guns (my JVC had them fail on me). It started that way and eventually I had a triple image of what was on TV, one in red, one blue, one yellow, and all slightly offset from each other. The fix was new projection guns (thankfully it was under warranty as they were about $300 each).

JVC MODEL # AV-48WP74 48 IN. BIGSCREEN TV.


I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce

Red and Blue shadowing (Where are my 3d glasses)


There are two convergence IC's that are bad and need to be replaced, as this happens to almost every rear projectionj set ever made. They are stand up IC's , on a heatsink and they start with STK. They are soldered into place and this set has no user replaceable parts inside of it. If you have no solid state repair experience, you really should call out a trained tech to assist you in this repair. A TV set is no place to be diggin and experimenting inside of.
