Have a problem isntlaling my new convergence chip?

This sounds like your convergence chips have gone out. If you open the back of The set you will see a big metal piece with fins on it on the front side the convergence chips are located. When these go they usually take out several fuses on the power board they must be repalced along with your convergence ICs get the letters and numbers off of the chips they will start with the letters STK you can order a set of them from suburban electronics for around $20 there will be soldering involved with this repair if you can solder this is a easy fix that will cost you less than $40

Go back recheck ICs make sure you didnt forget to solder some of the Pins. Ch small blue capacitor next to hori output Transistor 2k volts,make sure it is OK,then resolder all the yoke plugins. Let me know if you need anymore help.

These sets have several common problems listed below.

Problem #1) Convergence

Symptoms:

• Screen Looks Distorted/3D
• Colors wont align
• Screen may look distorted
• No Audio/Video - makes a chirping sound.

Problem #2 CRT Fluid has clouded over. Symtoms

• Dull looking screen
• White looking sceen
• Halos around objects
• Red/Orange looking

You can see some examples and find a fix here...

I have a few questions and A VERY GOOD IDEA OF WHAT IS WRONG WITH YOUR SET.

Go into the customer menu and select Convergence: if the blue is skewed OR WILL NOT MOVE IN SOME DIRECTION, the set has a bad convergence IC.

Based on WHAT YOUR MODEL NUMBER IS this set uses TWO of the STK-392-110 CONVERGENCE IC's.

If you have some skills at soldering and are handy I can give you general instructions and also tell you what you will need

2 new STK-392-110 CHIPS
1 good soldering iron
Solder
de-soldering braid or wick(to remove solder)
Some liquid solder flux (used to un-solder and then when re-solder new parts in.
Some heat sink compound(applied to the back of the new chips before installed)


THE ABILITY TO GET AT THE CHIPS---I can if you want tell you what is involved here--this is really the hard part on most of these sets--yes, each chip does have 18 pins that have to be unsoldered/ soldered in.

Let me know if you are able to do it or if you HAVE ANY QUESTIONS OR NEED ADVICE--I am here to help..

your Convergence IC chips and resistors arre failing you need to replace them

below is a general disscussion post for a Philips TV which will help you to understand your situation and what you might need usally you will need (2) IC convergence Chips and usally (12) Resisitors what have to be soldered onthe the board after you remove the old ones. this fix usally cost you to do it yourself $30, to have a repair man do it cost around $300-450 a new board if avalible usally costs $250-300

Sorry, for the bad new I hope you have a friend that knows how to work on circuit boards...
good luck,

below is a general post about a philips TV Convergence problem you can read about keep inmind your CHIP and RESISTORS will proball be different type....

you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted pictures on, check out page 3

Where I got my parts that worked:
Suburban Electronics http://www.suburban-elect.com/
Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads



What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux

sounds like a convergence chip problem...

here is my general post for the 51 inch you'll have to look at the link for the manual and check to see if you have the STK392-120 chips or somthing bigger in the 60"

you should be able to repair the traces if you do it carefully. That small circuit board is way over 300.00 if you can find it.

The convergence problem is likely to be in the convergence power supply which is located above and between the two boards which lie flat inside the chassis. The power supply has a chip on it which is a common problem (If it is not the transistor type then change the whole board.) part number on the chip where the metal heat sink is located. Part number may be STK 730-010 or STK 730-130 both number will work and must be unsoldered and new soldered in.

The convergence board is bad in this set. Samsung no longer has this board in stock. You will have to take the board out and rebuild it by replacing both of the STK convergence amp IC's These IC's are soldered to the printed circuit board. They will be standing up against a metal plate, called a heat sink. They are black in color and are about 2" by 3" . They have white lettering on them that start with STK and the some numbers. You get those numbers and go to mcmelectronics.com, enter the exact number of the IC and order two of them. Before you install the new IC's you will need to apply some heat sink compound onm the back of the new IC's. This heat sink compound is avaialable thruogh radio shack. Good Luck
