    Thanks to this forum for some tips.

    If your Samsung HCN4226W is having blue shadow or radiant(double cross), first check your blue crt. The coolant could be Contaminated.



    I read thread in this forum and open mine toady. Instead of it being clear, it was milk or cloudy. I drained it but I bought the coolant online but hasn't arrived.



    If you have similar, I can give you tip on how to take the CRT out rather then messing with the YOKE.

    Thanks Ladywinn. I meant to post that. You're a veteran. I might get my Hi Def cable from you once this thing works. Your website pricing is great. Are those new or used items?

I charge 285.00 at my shop ,so if you cannot fix it your self you are looking at repair anywhere from that price or more .You have 2 STK ics these are your convergence Chips .You would need to replace both of them.If you can solder you have it made.

Hcn4226w tv blue convergence blury


Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and check power resistor for leakage, if values are not exact you have to replace them. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice. Please do rate the solution if the issue is resolved or else revert for further assistance.


Thanks

Is $400.00 REASONABLE FOR REPAIRING A CONVERGENCE PROBLEM ON A sAMSUNG hcn4226w?


no it's not reasonable at all.if you are positive that it is a comvergence problem you can go to bestbuy and do a part search and get a complete convergence board for aroung $100 depending on where you live because of shipping. i live in ohio and i just replaced mine and it cost me $95.67 thats tax and shipping and was very easy to install about 10 minutes.

Samsung HCN4226W Service Menu?? For convergence issue????


The resistors on the new module are not 100% Identical in resistance to the originals on your board, to access the svc menu you will want a service manual and will require some patience. It can be tricky I would personally call a repairman with convergence in mind. Or order a manual and read the conv section several times. http://www.eserviceinfo.com/index.php?what=search2 Is one site, might have to purchase one.

Convergence problem?


That board, P/N Bp94-00155a should fix the problem and be fairly easy to replace. Make sure you unplug the TV before starting the repair though. Duh!
