I have an Apex Digital TV Converter box # DT250A. Today, all of a sudden my TV screen went greenish and then the picture on my TV went out ( static looking screen ). The light that's on my Converter Box...


The DT250 likely has one or more bad 470uf 25v capacitors. You should replace all four. Look at some of these youtube videos for how do do the replacement.

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.

Your APEX tv has a convergence problem which is fairly common.

Check with www.TvRepairKits.com. they may have a kit for your model.

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.

Your Convergence is off. Go through the menue to the CONVERGENCE and follow the on screen instructions.

Start with the RED gun and align each cross point starting with the upper left corner.

You will be pulling the red to match the green.

If the television shuts down during this process, it will reset the convergence and you can try again.

After you get the red gun perfectly aligned with the green, start with the blue.

follow the on screen directs and don't forget to store.

Use the remote for these adjustments.

I hope that this helps..

Apex rear model?


I would say it's a adjustment you will need, is the convergence aligment ok, to adjust this you will need to find the adjusment block in the front, this is a black unit about 4" x4" and has lot's of wires that comes in.
On this block there will writing on it focus, and screen, well your half way there.
Adjust the green screen control downard to see if it adjuses your green problem if it does, here how you adjust the rest.
First go to your menue, turn the colours off. yes off.
next put contrast to max.
next turn your brighness to 40%
Nest ajust the screen control until you no longer see any trace line of the colour you or seing so that at the end product you het the best black and white picture you can. This will give you the end resolt for best picture posible.
Adjust the other colour after, to see if you or close to the corect adjustment go back to the menu and turn contrast down you shouldn't see any trace line.
Another problem people don't understand this unit have to be clear once's every 2 years.
This I won't explain it's a very long process if done right . Rear projectors has to be clear because with time you will notice the picture looks like you have catarack. or white filtering of the picture. This is when you know it need's cleaning, I do it all the time when I go to customer home, yes I do house call's. I think I'm the last one out there, most shop what's the tv in the shop mostly to be able to control the price there about to hit you with and if the customer doesn't pay there just sale it, they have the control and not you.

I hope this help, keep in mind it's very expensive to have tv repairs, but you have to pay, this what keep's tech going without them, well you can just imagine.
