Apex TV model GB4308

Customer really messed up the convergence on this set. He was actually able to get into the service mode and change settings there. I am not sure exactly what he did and he "can't remember". Anyway, I tried to adjust again in Service Mode but no matter how hard I try convergence is till not acceptable. There remains severe bowing on the sides and I'm not sure exactly what parameter is responsible for this. I need someone to give me exact factory settings for all parameters so I can at least get the set to a point where it can be adjusted.

    I am really not happy with your response. If you notice from my post, I specifically requested the factory settings for this set which you decided to ignore, or do not know anything about.

  • Tony Harrison Oct 08, 2007

    If you don't know what the factory settings are for this set - all of them- please do not respond. I need to go into Service mode and enter all the factory settings for this set, or very close to them. That is the only way to solve this problem.

Linear amplifier set is to blame, and a good old fashioned trip to the repair man is all it needs. this prob is caused by incorrect or un-natural setting being imposed on the set causing the vertical settings to be 'shortened' and the horizontal simply over compensating! as a repair guy myself i can give you a rough quote: i would say, $70-80 2 hour repair job, with new parts. DON'T settle for more than that! good luck by the way.

Auto focus button was pushed a few times and now our Apex TV won't focus at all.

likely a convergence failure. if you push the button over and over, sometimes it will throw the set out so far that it cannot align anymore.. the sensors need to see the lines to do the auto alignment. you probably need new convergence ICs, repair is tricky and requires soldering. estimate = 200-350 $

From reading your question i have decided this isn't something you have any hope of fixing yourself. Take the TV to a service center/technician they will be happy to fix any "vertical convergence" issues you may have.

Convergence is when you aim all three of the projectors, your tv has three, so that the images they produce all line up with each other. This usually doesn't generate a white line across the middle of the screen though, there is a button on the front panel of your set that automatically converges the three projectors, you can try using that.

My projection tv picture is messed up

I'm not to sure what exactly is wrong with your tv, but I do know that it is NOT the convergence board. I have the same problem with the same model and was told to replace the board. I waisted $85 bucks. The only other thing that I can figure is it must be the STK's inside the TV. If you fix yours please repost and let me know so i can fix mine.
