All of a sudden my 6 yr old samsung HCN653W has a

Could be a bad blue TUBE. Samsung tubes were NOT too good.

replace the board or convergance IC. IE... deflecton/convergance

Replace Both of your STK ICs Big black ics will have part number on them example STK392-110 also there is 2 resistors 2.7 ohms near STK replace them Call Mats for Parts 1-800-628-1118

This is a very old post Do you do need Help?

I had a repairman replace the convergence boards. The picture is fine now however red & green colors are messed up.

YES in this set there are two convergence ics called stks...on for red and one for blue...and green is controled by both.

Common problem known as convergence. The most common reason is the failure of convergence ics. these ics fail all the time because there big and get fairly hot. there is a possiblity that it can be reconverged if the convergence cuircit is not damaged

ussally when u get coloerd outlined this idicates ether a convergence or a focuse problem.. the green convergence has become shifted. not lineing up with red and blue.. this also could indicate a green crt problem.. my advice is to get a tech to check it out.. it could be a simple adjustment or a whole new green crt

i have found when samsangs convergence are out of range perfect focus will fail. if the are out of range a technician will try to adjust the set in service mode. store these values and then this will be the base for the perfect focus. If the set has a bad convergence cuircit then they have to be replaced.
