A professional tv technician can realign convergence or you can try to manually realign it yourself via little knobs under one of the tvs panels near the lamps.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Have a philips(model 55pp9401) 55 in screen.just had the color (guns/chips/moduals?)changed because the blue was warping the top of the screen,also had some burned transisters.seemed to work just great...


unplug the convergence yoke plugs all 3 of them and then see if the set powers up. If it does the troubles in the convergence circuits if it doesnt you likely have a problem with the LSB pc board. If you need more help let me know.

Color convergence out on rc 52 inch projection tv


If it is way out, it is more that an adjustment. It takes a crosshatch generator to do the convergence.

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.

Convergence problem???


I am a TV tech and have had experience with this type of problem on many sets...So Far the only trouble is the 2 output ic's stk392-110 which should be replaced with the upgrade stk392-180..All three Color Amps are within these ic's for both horizontal and vertical convergence. Sometimes a resistor or two will burn out as well because of the short in these ic's. Be sure to be extrremely careful unsoldering and soldering and use good heat sink compound and fasten securely to the heatsink metal. Manual convergence calibration may be necessary after the ic's are replaced. First try Touch Focus after the ic's have been Properly replaced. This repair should be done by competent personnel and takes about 3 hours because of dis-assembly and re-assembly time. I am writing this because i have seen on this site mis-leading info. i come to these sites myself to verify part numbers and to see if there have been additional complications such as complete shut-down.
