I replaced the convergence ICs and the resistors on my Panasonic PT-53wx54j. When I powered it up, it worked great. After about an hour, the blue started to blur across the screen, and then the TV shut...


nwlounsberry,

Check all the components in the vicinitry of the convergence ICs. Concentrate on the diodes, resistors and electrolytic capacitors. In fact all the more they cost I would just replace all of them. If I had to guess I would say you have a bad electrolytic capacitor. Cost is minimal. Parts are available at http://www.mcmelectronics.com .

Thanks for using FixYa and for the great rating. Please consider a testimonial.

Red ghosting


Your symptom sounds like a damaged convergence IC.

This is a common failure for this particular television. The blinking lights indicate a short in the power supply

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. They are secured to a very large aluminum heat sink2.gif. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics2.gif in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts. I believe that these kits come with instructions for your brand of Television.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

I have a Panasonic PT-53WX54J that will not Converge


you need to replace or have professional convergence amplifiiers. If know how to desolder and solder you could repair yourself or in home professional tv repairperson will cost you $275-$400. The convergence adjustments via remote are half the battle the IC's loose clarity over time.

Pow lite flashes three times it tries to turn on then shuts down


LED 3 times blinks shows problem with convergence out section in TV and may requires convergence out ICs replacement.
If you are familiar with TV repair and can solder parts on PCB then let me know to provide you more technical info.
Thanks.

Blue wave coming up frpm the bottom of the screen on the lower left symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change 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.

Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.
