2.2 ohm resistor blowing after convergence repair

I had a convergence problem with my pt-47wx49e, as many have, and replaced the IC units and unit still did not work. I just replaced the 2.2 ohm resistor in the R7035 slot and turned on the tv. The resistor started glowing red and then the tv shut off. Should I replace all 2.2, 82, and 120 ohm resistors around the IC units? Or is there another issue that I need to address? Football season is in and I need to fix this tv. Thankd for your assistance.

It might be the issue on the board. I would recommend you to show it to a repairman

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.

Your symptom sounds like a damaged convergence IC.

There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. 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 Electronics 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 hope this information allows you to resolve this issue.

maybe the convergence resistors? sometimes when the ics blow a resistor or a few blow

Detailed problem per your response


The problem is that the ICs may have been blown because the resistors were bad. Just as a double check before you replace anything else. Please confirm that the STKs are STK392-110. Also, replaceing them with STK392-150 is a valid upgrade, I'm not sure about the 180s, but I'll check. Both the STKs and the resistors need to be changed at the same time.

The hour glass view you reported: Was the bowing on the top and bottom or on the sides?

Thanks,
Dan

Continued convergance issue.


I have heard from a few people that the higher value IC (150, 180, etc) do handle more current, but also that they *draw* more current, as well. Taking a guess, it may be simply that the 180s you installed were pulling too much juice from the resistors, which is why they popped. These ICs were used in many TVs, so it may be that the Panasonic doesn't have as much tolerance for the 180s' power requirements as, say a Hitachi.

Luckily, resistors are pretty cheap, so it's probably worth the few bucks to replace the resistors when you drop in the 110s you have in hand.

Just click below for convergence repair kit;

http://servicemanuals.vstore.ca/

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. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Hope this may help;

Panasonic pt-47wx49e the green line color his curved in the middle of the screen can not converge


You need to replace both convergence Ics and the six 2.2 ohm 2watt resistors. The Convergence ICs are STK392-110 you can get replacement ICs and resistors at the following link with free instalation instructions. Here is the link.
