Yes sir anytime you move a projection set ,theres a chance that the convergence could go out of alighnment as it dosent take much. First off your gonna need a cross hatch generator and a service manual and a good kno how on convergence alighnment as when you adjust some controls you need to counter it withanother completely differant alighnment control> so in some cases to get a section or a linearity correction your gonna spend some time. I myself remeber one set I spend 5 hours on after a customer tryed to adjust the confergence them selfs. Not only did it cost a bundle to realighn the gentleman need to go to the hospital as i results of touching a spot on the chassis that he shouldnt have and gave him a shock that threw him across the room. My advice, unless you have convergence experience is to invest in a service person to come out to your home and adjust it for you. I would try first an authorized repair center as they should have all the tools and secrits to the convergence in that set. And Please without electronic experience, even an unplugged set can harm ya. Good luck Try the # and the link 800) 252-5722 or proinfo@jvc.com

How to get pass st math kickbox level 9?


Try the site below.
How do you pass kick box level 9 on st math

You can also check this out.
To pass the Kick Box level four at 50%, you just move one of the blue bars down to the bottom, many squares work, but I did bottom row, second box from the right. Next, put the other blue bar in the second row from the top and the second box from the right in that row and then hit go.

Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and check power resistor for leakage, if values are not exact you have to replace them. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.


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


Thanks

Rylee

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

The first suspect on a LCD projection if yours is a KF50WE610 is the lamo itself. The second issue with the blue line is a possible bad LCD panel. There is NO convergence settings on a LCD set.
