If anyone has a digital copy of the service manual or owners manual for the apex GB55HD09W please let me know. I have been trying to find information on how to fix it and I saw this forum but I still haven't been able to actually find any manual to fix it. thank you

Hi, Please run the convergence feature on your TV. Its giving you double image because the red, green, and blue guns are dis aligned. By running convergence it will realign the guns properly. You need to run the convergence feature at least once a week. Please note this is only for CRT rear projection TV's and I assumed it was. If it is an LCD rear projection, then there's nothing you can do to fix such thing, but call a repair person. But if doing the convergence doesn't fix the problem, you need to call a repair person. But I hope you won't have to refer to the manual on how to go about it Good luck!
I have this TV and have fixed this issue. If you cannot adjust Red or Blue convergence, then your STK ICs are defective. The signal board or Digital convergence board is not able to adjust sig lines on the deflection board so pushing buttons does nothing. The STK's are your amplifiers for vertical and horizontal. This will require dissassembly and soldering. You'll need 2 STK392-020 IC's and 125v/5A pico fuse or buss fuse..
The STK's are mounted on 2 massive heatsinks. Can't miss it. Word of advice, LABEL the 3-4 Pin plugs B,G,R from left to right. These are your Vertical and Horizontal coils for each tube. Don't mix them up. I did and the tv survived luckily. Chances are if your STK's poped, then they took out the -25v line. Take out the power supply that is mounted vertically on the right. Look for a row of axiel lead fuses with "SOC 5000" printed on it. They look like white rectangular blocks with leads. Check them all. Particularly RF817. Sits next to RF814. The service manual lists it as a fuse and NOT a Resistor-Fuse like the label suggests. I found more than one typo like this. I replaced mine with a generic 125v/5A fast blow buss fuse. Soldered in a holder for it. Should work the same.
Took me abit to realize it was a fuse on the power supply. This -25 line traces to W057/W058 next to the first STK chip. Explains the symptoms.
Your set needs two convergence ICs they are STK392-020 you can get replacements at the following link and they procide free instalation instructions with pictures so you can do the job yourself which takes about 40 minutes from beginning to end. Heres the link. http://servicemanuals.vstore.ca/
Replace both convergence ICs number STK392-020 you can get replacements at the following link and they provide free instructions woth pictures so you can do the repair yourself. http://servicemanuals.vstore.ca/
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.
