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..

SOURCE: NO SOUND FROM MY APEX GB5108 TV

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.

Just click below for convergence repair kit;

http://servicemanuals.vstore.ca/

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left and fuzzy images this is a symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Hope this may help;

SOUND NO PICTURE ONLY RAINBOW


I just fixed this problem on my neighbor TV. I don't have a manual or schematic, and didn't pay any attention to the reference designators, so I will just have to describe it. The problem was a bad solder joint. Visible thermal fatigue. Looking at the main board, (didn't even need to slide the cassis out). There is a small, narrow, vertical board in the center, adjacent to the yoke connectors with a funny looking little transformer on the very top. Check the connections on that.
