Convergence problem


replace the convergence ic. the IC# is STK392-120, replace this two ic at the same time. then put some silicon grease on the back of the IC for better heat transfer. some will work on replacing just 1 IC but I would recommend to replace both per philips advise. hope this help. regards, cebuwano.

Red Convergence issue. Can't adjust. 3d picture.


If you can solder, try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. Please note that there are potentally dangerous hogh voltages present inside hte set even when unplugged.

Keep us posted on your progress.

Convergance


Its a straight forward repair just take out the convergence ICs and solder in two new ones. takes about an hour from beginning to end. just apply heat sink compound on the new ICs before installing them. And in that model check the resistors right next to the ICs as 1 or 2 of them often burn open when the ICs go out. Let me know if you need any additional info. The ICs cost about 10.00 each you will ned two.

Phillips chirping


two STK392-120 convergence modules that usually cause the beeping. So I changed them both again, but I also found two open 7.5 ohm resistors are in the general area of the convergence modules, and I replaced them as well. I also replace 1 swollen capacitor that was probably going to blow in the future but not really a problem yet.

Either a convergence problem where the 2 stk's need changing and resistors in that area, or the vertical Ic is damaged and needs replaced.

Help tv comes on and goes right back off


A common problem with this model is the convergence IC's on the small signal module going bad and keeping the set from staying on due to protective shutdown circuits used. If that is your problem, the easiest fix would be to replace the module - Philips Part #313503710091, about $200 or so, or have a technican replace both IC's Stk392-120, Philips Part #932212344682 about $45.00 each plus labor and service charge of course. Other parts could be bad, but this is likely what I would try first.
