1 Answer

Colors all over

Hi I just recently replaced the convergence ic's in my big screen. Everything went ok but when I turn the tv on all the colors are distinctivly separated.Tried manual and auto positioning ,but certain colors and positions will not adjust.Could I possibly hooked something to the wrong lead or can I set these a different way? Regards Tim

Did you check to make sure none of the IC pins are bridged with solder? Also did you check the resistors that power the ICs in this model usually 1 or 2 of those resistors will go open with the ICs.

This tv has two big black ICs as convergence output on deflection circuit board that are defective and causing problem in tv, IC number is STK392-110
replace both ICs to solve tv problem, also chekc for faded color big resistor nearby these ICs or those got burn mark, replace these resistors with same value, aslo check cold/ dry solder joints in deflection circuit board and resolder these joint/ connections.

Tv turns on but the screen is black. Before it went black we were haveing bands of color on the top and bottom and everthing was kind of like in three D they were all three colors and like 3 of them there.


Ur tv have convergence problems,now the 2 STK convergence ICS are completely dead,U lucky u tell it was 3D screen,before it go completely dead,went black screen.Or ur problems it will very hard to diagnose.U now how to do soldering?Must replaced 2 STK convergence ICS,some or all it resistors.Tries Websites Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.

50h72 replaces ic's but still don't work


Did you replace the convergence resistors along with the Ics? Also if you replaced the ics with open resistors you have most likely ruined the new ICs. You can get a convergence repair kit for your model at the following link which has the ICs and the resistors for your model, and they provide free tech support and instructions.
Heres the link.

JVC big screen t.v.


convergence fail. replace convergence ICs with stk-392-110 can be accessed through the front. take off the speaker grill and panel behind that. there will be a large heat-sink under the picture tubes that is the convergence power board. disconnect all cables(mark any that look the same) going to and from that board de-solder the amps --- replace any burnt or open resistors--- plug everything back in turn the tv on and adjust any alignment needed in the regular tv menu.

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.

Sony HDTV Convergence Issue


No, You will not solve the problem with only changing the convergence IC, associated resisters may also be required.
Beside of that, after spending time to get parts and replace the ICs, you need to make and adjustment the color lines (about 14 lines)
This adjustment without experience will take you about 3 to 4 times and 4 hours each to get thing right (if you areskillfull, most of people failed this adjustment).. The total time spend for this problem would take you full 24 working hours.
I successfully adjusted one set of my big TV (95%, need more more round)), on another set one I failed.
