I have a Panasonic HDTV Model PT-53WX53G. I am getting a 3D / Double screen effect.


This is the convergence chips. They are 18 pin Amplifier IC Chips that control your three tubes to line the colors up. They are only about $20 each (there is two of them). They are difficult to replace if you dont know how to solder/unsolder. There is usually at least one resistor or fuse that will blow when the chips go out, you must replace this also. If you have no experience in electronics then i'd suggest you take the set to a pro.

PT-53WX53G still shutting off-3 blinks


have you checked the 2.2 ohm 2watt resistors? If the led blinks three times the resistors will almost always have at least one that will be blown and need replacement.

Tv still turning off blinking three times after hori ic replaced


Three blinks is short protection.

97% of the time it means one or more of the 2.2 ohm blue resistors around the two convergence IC's is OPEN.

There should be 8 or 10 of them: light blue in color and will have 2.2 printed on them ------look for any that are slightly discolored or white in the middle.

What happens here is if one opens====one of the two convergence chips got it----they can be tested in place like testing a fuse===no reading across any of them and it is gone-----set detects no voltage reaching the chips(Usually STK-392-110---black in color and on metal heat sinks with fins side by side.)

DO NOT JUST REPLACE THE RESISTOR IF YOU FIND ONE BAD=ONE OF THE CHIPS GOT IT.

I have start to finish, step by step instructions showing what is needed and the best way to replace the chips etc.

FIRST: LOOK TO SEE IF any OF THE RESISTORS ARE GONE. (BAD)

If you want the instructions let me know and I will post them here for you.

Regards, SD TECH


FYI= Whoever told you to replace the output transistor does clearly not know these sets very well as it will produce a 5 blink error code.

Location of convergence chips in Toshiba 57H81.


hello if you can use a soldering iron you shouldn't have any problems but you will need to test the resistor in front of the ic and the capacitors at either end of the ic ! the ic usually located to the right hand side of the tv behind the tuner board connected to metal frame called a heatsink 2 big black chip good luck

Can I Fix a Color Seperation Problem Myself On My Television?


The convergence Ic's need to be replaced. This is not easily done unless you have a good soldering station and some technical experience.

Panasonic PT-53WX53G power problems


Just click below for convergence repair kit;

http://servicemanuals.vstore.ca/

The 3 blinks symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-150ICs and it's associated resistor,this resistor automatically chagne value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Panasonic pt-53wx53g tries to turn on but goes right off


That is indicating that the convergence circuits have shutdown the set. You will need new Convergence ICs. They should be STK392-110 or STK392-120 either number works the 120 being the better chip. I will post a link where you can get the new ICs and they provide step by step instructions with pics so you can do the repair yourself. You will find your IC numbers under the section titled Convergence ICs just click on that and you will find your STK numbers.

Converange chip-Where can I order one


This is very strange coincedence it seems the more I search this problem the more people I am finding with the same issue. This morning Aug 3 2007 I turned on our Panasonic PT-47WX42C to find this convergence problem! (distorted colours-off alignments) I, like yourself Hultsie would love to get the schematic diagram for our unit and change out the IC(s) myself. If we work together I believe we can accomplish this task! Please contact me at my_kill@yahoo.com if you would like to give this a go! I certainly will try to exhaust all avenues before I part with hundreds of dollars for something I know I can service myself. Oh, the defective IC(s) will more than likely have the values you need written on top of the chip...once you know the ones that need changing your local tv repair or even panasonic (if there close by) will sell them to you.
