Question about Apex Digital GB43HD09 43" Rear Projection HDTV-Ready Television

1 Answer

Convergence and picture problems

I had an APEX GB43HD09 projection tv for 4 years. Recently, both the convergence and the picture got mess up.The top and bottom of the screen form semi circles. Pointed towards the top and bottom so that the middle gets pushed together and the edges are stretched. And I'm seeing triple pictures in 3 colors. I had the convergence problem before and was able to fix it in the setup menu, but this time nothing works. I think something is wrong with the projection tube but i'm not sure. If you have any sokutions to thses two problems please help.

    I have a similar problem, if I tap on the left side of the tv by the base, it correct it. Not a long term correction, but fixes it.

This TV probably uses two convergence IC Packs that will need to be replaced and be re-converged. There may also be a resistor or two that may need replacing as well. The projection tubes should last another 3 years or so.
