Well? I replaced the ic's and a repairman said was out..... And I still have the same problem with my TV??? The screen is bowed in from the top and I see multicolors... Before and after fixing the ic's, when I go to the convergence adjustment screens? It won't let me adjust the red and blue crosses into the white; also the white cross looks green??? What else can it be, that's wrong with the convergence??? Help me, please???

Re: Replaced two IC's and still the same problem????
U say the set is bowed in from top, could this be a foldover? If so then the ic problem may not help. Check to see if any fluid leakage has dropped on your deflection board. If so then you probably will need to clean and replace some capacitors. This is kind of common with the philips projo's. Look around crt for fluid leakage and on board.

Hi, A component called IC STK needs replacement, You didn't wrote Model No. of TV otherwise i must provide you the specific part number of the said IC, Anyway contact any repairman nearby to replace the said IC. Thanks.
Could be shorted convergence chips. There are two of them in the TV. If they short they will shut the TV down. One quick test is to desolder both of them...then power the TV on..if it fires up the chips were shorted and would need to be replaced. You can get a complete kit from www.TvRepairKits.com
The problem is that the ICs may have been blown because the resistors were bad. Just as a double check before you replace anything else. Please confirm that the STKs are STK392-110. Also, replaceing them with STK392-150 is a valid upgrade, I'm not sure about the 180s, but I'll check. Both the STKs and the resistors need to be changed at the same time.
The hour glass view you reported: Was the bowing on the top and bottom or on the sides?
Bull!!!!!!!!! i dont think he knows what hes doing.... you can send the board into ptscorp.com have them check it out, it's the board with big black iC stk392-XXX send that one in, you convergence is done thru the menu system.
My version is :
For safety reason you should replaced them ( Horizontal ic,Vertical ic, Deflection ic) and olso all the big capasitor nearest the ic....that's my version....if you have big budget for it....he..he....
