Your Convergence is off. Go through the menue to the CONVERGENCE and follow the on screen instructions.

Start with the RED gun and align each cross point starting with the upper left corner.

You will be pulling the red to match the green.

If the television shuts down during this process, it will reset the convergence and you can try again.

After you get the red gun perfectly aligned with the green, start with the blue.

follow the on screen directs and don't forget to store.

Use the remote for these adjustments.

I hope that this helps..

I had the same problem with mine, it turned out to be a fried audio board. I simply used the audio outputs on the back of the tv to drive a new reciever with surround. Sound a heck of a lot better than the speakers built into the tv.

Convergence and wavey picture problem

Actually you have 3 problems. The two that you listed and the third which is: Apex does not support their units. Ask anyone who has tried to get any service. Your problem sounds like a bad digital convergence box. I fix this problem several times a week but on name brand sets. Cost is usually less than $100 for the part. Some problems with Apex equipment can be fixed if the part is a common off the shelf part. That is not the case with your problem. Apex equipment is cheap for a reason. All posts that I have read say that they do not last long and you can't get parts. That has also been my experience as a technician. We don't even accept Apex units for repair anymore. Next time spend the extra money to buy a name brand unit and it will more than likely be repairable.
