Hitachi convergence If i replace both original ic's (stk392-110) with stk392-180 will i have to replace any or all resistors or any other parts?

Ur tv still have dead resistors parts,test all 12 resistors parts around the 2 STK convergence ICS and changes some more dead resistors parts or changes all 12 resistors parts for sure.If tv still have the same problems after tested and replaces more resistors parts or all 12 resistors parts.Than some how when u handling and replacing the 2 STK convergence ICS and resoldering the 2 STK covergence ICS u short it out the 2 STK convergence ICS by resoldering without proper grounding ur self not to allow for static electricity to kill the 2 STK convergence ICS or u using a soldering iron to high of a wattage for doing soldering ICS work.

Yes, you have a convergence failure. Usually requires replacement of 2 X STK ICs and any burnt resistors associated with the function that is faulty.

Look at the user menu and compare with images on our Convergence Gallery. Try to adjust in the convergence adjust menu. Identify the functions that do not work and make note. When you replace the ICs, pay special attention to the low ohm resistors for the non-working function. They will be located near the colored plug associated with the non-working function. If red vertical will not adjust, check resistors near the red plug.

There are many posts and websites that offer "new and improved Convergence IC substitutes. My advice is to use the original part numbers and replace any burnt resistors with original values. Many ICs purchased on the Internet are very poor quality and do not work. Many users get substitute replacement ICs and never get their TVs working again.

If you have other electronics repair experience, this job may be done with some chance of success. If you have no experience, there are many secondary problems that can and usually do appear. Determining how to fix the secondary faults and how to correctly align the TV is difficult without prior convergence repair experience.

Some of the common problems encountered are:
1. Poor solder techniques, resulting in damaged PC boards or poor solder connections.
2. Poor quality or wrong parts installed and recognizing this problem.
3. Resistors open or burnt. Some resistors are weakened by the initial faulty IC. Replacing with a "good" IC and starting the TV causes the weakened resistors to burn up. IC may be ok but there are one or more open resistors that measured ok when ICs were being replaced.
4. Wrong ICs used, causing resistors to burn up.
5. Resistors that measure normal and become faulty when heated by current flow.
6. Recognizing that convergence circuit is repaired correctly and alignment is needed.
7. Major alignment in service menu required because data is corrupted by multiple tries of magic focus or manual adjustment while faulty circuit conditions exist.
8. Major alignment required because user adjusted centering rings or physically changed mechanical focus adjustment, then mis-adjusted convergence settings trying to correct mechanical alignment faults.
9. User has not connected plugs and connectors correctly and caused secondary damage or mis-alignment trying to correct secondary issue.

Physically replacing the ICs may appear simple but recognizing if a fault still exists or if correct repair is required causes many attempts at repair to fail. Keep it simple. Replace with good quality original part numbers, measure suspect resistors and adjust only what is necessary.

There are only 3 things to fix, IC failure, resistor failure and user induced secondary faults. Data processor and memory is bulletproof.

Yes, You will need to replace the 2 convergence IC's. Hitachi part # CZ01341. Generic part # STK394-160E These are the upgraded replacement parts. Also look for any burnt resistors near these IC's.

The color has gone crazy on you because your convergence IC's have gone bad.
These operate at a very high temp, and usually only last 4-5 years. 
If you remove the back of the set, you will want to look for the BIGGEST heatsink in there, on that heatsink, you will see 2 lage IC's , probably STK392-110, or STK392-150's you can go on ebay to order the new ones, but MAKE SURE they are Genuine SANYO IC's and not counterfiet cheapies. the cheap ones may only last 2 months..
You will also need some "Heat transfer paste" - you can pick this up at radio shack.
Once you remove the old IC's, test all the large resistors near them.. pull one side of the resistor out of the board so you can check it out of circuit. they will usually have the value in Ohms, printed directly on the resistor, but you may have to use the resistor color code to find out what value they are....However, usually if there is any damage, the resistor will look like it has been HOT or fried. replace the IC's and any bad resistors, and you should be good to go.
If after replacing the IC's and any defective resistors, the convergence is still bad, make sure to use a multimeter to check ALL fuses on the boards, --- sometimes when the IC's go, they will take out a fuse to the convergence power supply. If you find any bad fuses, replace them accordingly!
Hope that helps!

ok i would suspect the yokes are shorted to ground somewhere. you can measure that. the dcu or the digital convergence unit... which is the processor that handles the convegence of the set. i would have to research and pull up schematics to know which output on the convergence chips that those resistors handle blue ver...blue horizontal..etc.. that might help to see which output is shorted.

dactag,
Working backwards now.......The burning smell will be the current limiting resistors near and in the circuit of the IC's
you changed..1 to 2 ohms, 1 or 2 watts.....caused by generic
replacement IC's STK392-110,120 or 150......Here is what to do to FixYa! First,please read some of my solutions for convergence
repairs...any brand,the info is generic,the repair parts are not....

1) REMOVE cheap IC's ! Replace with Hitachi part # CZ 01341
upgrade Mfr by Sanyo STK394-160

2)Replace any / all burnt or changed value resistors

3)Re-test to see any symptom....DO NOT CONVERGE

4)Think about putting the original DCU back,since it was
not the problem .......

5) Now where are we at ?? ............................T.

Ditto CTF1800's comment....Check RP-41 1.5 ohm 2 watt and
other low value resistors near IC's mounted on large heatsinks.

STK392-110 original convergence IC's can be upgraded to
Hitachi # CZ 01341 new number STK394-160E for greater reliability.......Hitachi also has an IC / resistor kit # X480295,
but I don't change good resistors, only the bad one(s).

Practice good visual acuity technique and ask questions!.....T.

Replace both IC's with Hitachi upgrade STK394-160E PART #
CZ 01341....about 30.00 each....check resistors near IC's...
can be bad 2.2 2W, for example......................T.

The fact that you used the term "magic focus" tells me you have a Hitachi projection set. When the colors no longer line up on a Hitachi projection TV, it means that most likely one of the convergence output IC's has shorted out. Sometimes a shorted convergence output IC will burn up a low value resistor too. I have also seen a convergence IC crack loose from the board and burn up 3 low-value resistors. If your set is using the STK392-110 IC's, it is probably a good idea to go ahead and replace both IC's with the newer upgraded STK392-150 IC's. The output IC's should be resoldered / replaced and the circuits checked and realigned by a qualified tech familiar with Hitachi projection sets.
