Question about Apex Digital GB5108 51" Rear Projection EDTV-Ready Television

51 big screen apex tv, convergence or verticle IC?

I have a 51 inch big screen and last year the convergence went out, the screen was red,green, and yellow and l smelled something burning. Well friday the screen goes black with just red, green, and yellow lines in the middle of the screen and the smell. You can still hear just fine. Could this be the Verticle ic or is it the convergence again? the only diff is the fact that the screen is black instead of all colorful like last time.

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.

Green color projection is lifting from the bottom left corner of the screen. Convergence adjustment for the green projection is unresponsive


Howdy,

The TV has a convergence problem; the IC’s for that circuit will need to be replaced. The cost for this repair runs around $450.00 or more.

Replace the defective Convergence Output IC Part Number (STK392-110. When Convergence Output failure is
detected, it’s recommended that both IC’s be changed.

Thanks for choosing FixYA, Big Irish.

The Screen looks 3D & Colors don't line up on my big screen????


If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

Just click below for convergence repair kit;

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left and fuzzy images this is a symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Hope this may help;

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..
