    IF CONVERGENCE will not adjust you have a bad convergence ic--most of these sets use two--let me know model number and I will tell you what is needed to repair it. SD TECH

There's a miror or one like this might have a ''aluminium sheet'' miror.
Open the upper back cover to see what going on there, pretty sure something run out of place...

Blurry vision on picture


This is a very common failure on Projection TV sets.
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.

Colors out of porportion, maybe a bulb went out


When you have a 3-d effect. this is called convergence. Is the picture disorted or bowed in. if the picture is bowed in then this is an indicaTION of complete loss of power to covergence curcit. I always check to see if you have the convergence option in the setup menu if you do not then i suggest reading the fl231 problem in the tips and tricks sectionl

This is a convergence board problem. Have a tech replace convergence IC's. The part no. starts with STK. If you are good in soldering and know how to test resistors, you can do it.

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

Either a bad solder connection on your convergence module or a bad convergence IC. Repair costs will probably be in the $350-$500 range.
