Picture went on Apex GB4308 Rear Projection


For that type of problem you will probably want to call a local tv repair shop and set up a service call. Average price is 60-80 dollars to have a professional check the set and provide you with an estimate. To me it sounds like maybe the vertical circuit has failed if you have colors across the center of the screen. Also there is probably a resistor and capacitor that need to be replaced on this one. Usually it is a repair that most shops will be able to handle for less than 1/2 the value of the unit which is the breakoff point for most people. I wouldn't suggest trying to self diagnose this one without test equipment. Good luck, Russmann..

Apex is its own beast, there are two boards in it that could be bad , the power supply where the AC goes in probably has bad connections on it, I have fixed these before with soldering of the power supply;
hope this helps

The APEX and most rear projections are notorious for poor solder joints. The convergence circuits on your TV get very hot and the solder joints weaken over time. In your case, the convergence STKs are the large chips mounted to heat sinks right up front on the left hand side circuit board. Remove the board and resolder the STKs using a good low wattage iron. If this doesn't fix your problem try replacing the STKs. They aren't that expensive. They have 15 or so legs so you'll need some skills removing them. Good Luck!

Random Blue Lines


You should'nt replace anything untill you get a multimeter and measure the voltages on the Power supply PCB. Call Apex in your owners manual and see if they will supply a service manual so you know what the voltages are suppose to be. Or that manuel is avail as a download at http://www.servicemanuals.net/ for 15.00 bucks! Then you will get a better idea on what needs to be done , instead of shotgunning the repair. Good Luck

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.
