Question about Apex Digital GB5108 51" Rear Projection EDTV-Ready Television
I came across an Apex GB5208 TV last week that someone was going to throw away. Now I hate it when something goes to the dum[ that can be fixed so I figured I'd give it a shot. The TV powers on and once it warms up the screen comes up but I can't get the colors to align properly. I've downloaded the service manuals and went through the S mode settings, but although the screen changed it didn't align any of the colors as I had hoped. Below is a link to a picture of the screen. I figured to see is to understand better. I'm a good electronics tech, but I'm new to projection screens. Any help or ideas are appreciated. http://img.photobucket.com/albums/v168/naviathan/GB5108Pic.jpg

I'm also seeing the same problem however in the manual it states by "pressing the P lock the cursor turns to white". This did not happen & while you can move the colored cursor to where ever you want, you can move the color.
The only way around this might be to physically move the color crt of red & blue as green is what to tweak by.
Of course, minor movements will be obvious & it's difficult to get to the clamps on the crts.

On the converge screen there is a store option. Have you tried that?

I'm having a similar problem with the same model. did u try going to the menu with 'convergence' on it? by going to that u can manually adjust the red/blue lines. my problem is after doing this, when i turn the set off/on the picture is messed up again. any ideas about that? ian

I am having the exact same problem. Have been throught the convergence, the s mode, etc, and cannot get it to line up. Can you please post if you have figured out the solution. Thank you

That's a GB5108, typo I apologize.
I've read about that one and it's the convergence memory board. That would be the circuit board behind the convergence ICs that has a silver casing around it.

tryinng to set convergence
color convergence problem
Same problem here, now have 2 bad convergence boards, one much worse than the other. I've reflowed the both with no luck. Any idea where to buy replacements? Is it usually just the socket mounted IC, or other problems on the board?
I have apex digital GB4308 rear projection that just won't come on. Can someone help?
I, like the rest of you am having an issue wih the convergence on my APEX rear projection tv. I have reset all of the convergence lines manually with no luck, then tried the factory settings option and that works until you turn the tv off and return to watch it later with screwed up lines again. Now the remote has gone out and a universal remote will not work in different functions, so I have a new remote that I have found on ebay....on its way. Anyone that can provide info would be forever thankful.
