Well to answer your question about repairing the set first.  There is alot of High voltage inside these sets.  You are also going to need a service manual. Then you will have to look up the part numbers for the two convergence IC's.  They will need to be unsoldered and removed. Then new heat sink compound will need to be installed on the backs of the new IC's and reinstalled into the set, resoldered, then you will need to go into the service mode and realighn the main convergence of the set, as the customer convergence adjustments just won't do the alighnment.  If you have the soldering skills and can read a schematic and follow directions, you should be able to do this and save a bunch of cash in the meantime.  If you do not have the soldering skills, or ability to replace these parts,  please seek out a pro to assist you in this repair.  Oh by the way the little tyke who was playing video games on the set, had nothing to do, what so ever to cause this problem.  It happens to almost every, if not every, tube type projection set ever manufactured.  Good luck, and let us know how you made out with this repair.

The service manual is HERE as a PDF but a bit pricey Just enter the number without the slash

Maytag: did you have any luck finding where you can get the parts needed to switch the chips out? Looks like I've having the same problems.  

Could you please give the part number for the convergence ICs?  Without the manual, I can't search MCM electronics for the part.

I paid $750 dollars for this tv almost 3 years ago.  I can get a better, new tv today for the same price.  But the repairman wants 350 bucks to replace the ICs.  He said he would have to touch up the solder points too.  BFD.  I'm sure that sounds scarey to most people, but not to me.  How can the ICs be worth half the cost of the tv when it was new, and why the heck would I pay that much to fix a 3-year-old tv?

He could sell me the ICs at a profit, but he won't do it.   He wants to charge me $100/hour to solder something.  He can forget it.

ok, I have the same 51MP392H as Mr Maytag.. just yesterday my TV started with the same thing his is doing. Seems like only the red cannon is out of alignment. It curves on the top and bottom of the screen. I pulled the back off the set (knowing full well the voltage dangers) and blocked the red canon. The picture was perfectly focused and 'converged', though without red,  I guess this correction is not simply tweaking that canon.  Could you explain to me how the IC circuit board works and what it controls? Also, visually what should I be looking for (i.e. printed ckt board, metal casing, etc...)?

Good Day to all

   My set has developed the same convergence problem I have ordered the chip off line from bluestar int. for around 9.00$ us the part # is stk392-120 I hope this helps you all.

  If someone has a copy of the print for this set and is willing to share it , or is willing to help with a couple resistor values please let me know

thanks Lsound

Isound, let us know how you made out with the repair of this TV set.  Are the IC's you got the original Sanyo type IC's?  You can tell if they are not because Sanyo will not be written on them.  The IC's you got are most likely the aftermarket IC's and are not the same chips.  Go HERE to see what the original Sanyo IC's cost and the reason you should use the proper IC's is that the aftermarket IC's do not have the same specs that the original IC's do. Sure they will work, but they will not hold up and you may need to do a lot of alignment after you replace them. Let us know how you make out with this repair.  Sonic, no I do not have this service manual.

Philips never suppored board replacement very well, but you might beable to find it from a company called PTS

i have the same problem and i just replaced both ic's and the problem didn't get any better it just changed the location of the problem on the screen. instead of the colors being more seperated on the left side of the screen now it is right in the middle of the screen. and for some reason i cant figure out how to make manual convergence in service mode. i have the downloaded manual and it says to enter that mode to press 0-6-2-5-9-6-index on the remote but my remote does not have an index button.  please help.

thanks a bunch that totally worked now i have a perfet picture.

I have replaced the ic`s in my set by reading this thread, thanks for all your comments and suggestions......unfortunatly i am still having a problem getting the red to line up.I have remote and the manual,I also am able to get into sam mode with no problem but what to do from there? Am i doing something wrong or does anyone know if i still have a problem...... my red will only move up and down ,will not move left to right...please help
