Question about Apex Digital GB4308 43" Rear Projection EDTV-Ready Television

Apex GB4308 43" tv have to set convergence each time I turn it on

I got a Apex GB4308 from a friend as it was having a vertical problem. I traced it down to a bad vertical chip and replaced it. Now I have full screen but until the tv warms up I have wavy edges on the edge of the pictures. like my menu for the xbox 360. That does go away as the tv warms up though. My main problem is that every time I turn on the tv I have to resetup the convergence. I have no idea what is causing it.

Replace your STK ICs and look for Bad capacitor by vertical IC 100uf 35v.

Apex GB51HD09 convergence

Please have it taken care of ASAP. It definitely sounds like Cold Solder joints on the convergence IC's. Cheap repair now, if you stop playing it. Every-time the convergence goes out, the ic's struggle to bring it back in and can't and therefor over heat. so please have it taken care of Pronto. Apex used a Samsung chassis which was a good chassis in that PTV.

Apex out of convergence

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.

Apex gb4308 43in problom

From reading your question i have decided this isn't something you have any hope of fixing yourself. Take the TV to a service center/technician they will be happy to fix any "vertical convergence" issues you may have.

Convergence IC's

Lines going across is a little vague but there is always the problem with the electrolytics (caps) around the vertical, be sure and get the one on the power supply too. Just change all you can find(usually 4-5). Thre are 2 convergence ic's if you didn't change them both, resolder the other one.
Then check the value on R519 for me.

51 big screen apex tv, convergence or verticle IC?

If the lines are thin and close together running horizontally, it may be the vertical driver, but that usually takes out the resistor and sometimes the diode in the B+ for the vert. Also you must replace the caps that caused the problem in the first place.

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.
