Samsung 47 inch rear peojection ic's

Now i have figured out my problem but then ran into another one. i am hearing conflicting stories about the part numbers. my t.v. i bought used after the owner did not pick it up after a repair. anyways there are two ics in this model and they have two diffrent numbers on them. one is a stk392-040 ans the other is a stk392-010. should this be this way or should the ic's be the same part number?

My 47 inch samsung rear projection tv, the perfect focus does not\r\nwork it say no senosr data can anyone help


Hi:
This is an indication of bad convergence Ic that needs replacing. There are two of them that needs replacing. you and inditify them because they are mounted on two large metal heatsinks inside the set. The part number you are looking for is STK392-110

You dont have to remove the aluminum heat sink. The ICs are attached with screws and then just unsolder the ICs from the circuit board and then replace the new ics into the pin hole locations after applying heat sink compound onto the back then screww the new ICs to the heat sinks then solder the pins. Very easy repair.

Adjusting the convergance


On my 55 inch rear projection Samsung, there is a menu option to adjust the convergence. There is a manual as well as an automatic option. It is easier to do with the remote control. My Samsung remote has a button called 'perfect convergence' or something like that. you can also get to it from the menu tree pushing the menu button on the front of the set. You need to scroll through all the options to adjust color, contrast, parental control, etc. You should find it.

I assume the same is true on the 37inch samsung.

How old is the set? A number of samusng sets have problems with two large IC's that tend to burn out. This causes the symptom of colored shaddows, tend to be worse the further away from the center of the screen. I just finished doing the repair to my set. If you cannot adjust the convergence, that is most likely your problem.

Good luck!

Not sure of the part number most use STK392-110 or 120s . You will need to look at the ics in your set they will have the IC numbers stamped on them they will have STKxxx-xxx whatever that number is thats the sanyo part number for those ICs

If both red and blue have moved evenly, I would re-solder your STK convergence IC's before they overheat and your forced to replace them.

You should buy a Service Manual for this set here http://www.thecdguyz.com/ before trying anything with your hdtv.

I bought my manual here and saved big $$$ doing this stuff myself.

Oh yeah, my service manual came on a cd and only cost me $13.00usd including shipping.

Merry Christmas!
