Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Panasonic IC's Slinte. You had mentioned the resistors that power the IC's may be bad as well... do I need to purchase these also? Or should I first fix the IC's?  Is there any way to tell? Omar

Usually you can see the resistors being a little discolored as they dont have color bands on them. If you dont notice any discoloration on those resistor you should be good to go. There are about 7 or 8 resistors right next to the ics they stand up off the boards easy to spot, just look them over real good.if you notice any discoloration let me know the code stamped on the resistor and I will give you the ratings of the resistors.

PT-47WX52F with bad resistors at R832, R7060, and R7066. Changed IC's before, but now these resistors are bad. What type of resistors are these, and how can I obtain them? Thanks


R832 is a 8.2MEG 5% 3/4 watt resistor
R7060 & R7066 are both .27 ohm 5% 1watt resistors,
You can get the full set of panasonic resistors from www.tvrepairworld.com under the Panasonic repair kits its listed as the PT47WXC43 Resistor Kit that kit also fits the WX52 and WX42 models panasonics.

Panasonic PT53WX42 dead with 5 blnks of power LED


Your symptom sounds like a damaged convergence IC.

This is a common failure for this particular television. The power light might be blinking 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 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.

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.
If you need further assistance please comment to this post and I will try to help you further.

Where can we get the best IC Replacement


always stick with the manufacturers brand ! but you will need to check the resistors on the IC lines to make sure thier values are not off , because that will cause the IC to go again no matter what brand IC you use. other components in line of the IC should also be checked for bad values as they can also cause malfunction and breakdown of an IC and its circuit components

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.

Panasonic sa -ak 27


This is a common error for these Panasonic units. I work at an authorized Panasonic service center and have repaired many of these.

This error is caused by either 1 of these 2 problems, both of which will require service for replacement of parts.

1. The amplifier IC is bad and needs to be replaced.

2. There are a couple of smaller components in the amp circuit that need to be replaced. One is a zener diode and the other is a resistor.

The F61 error is caused by a bad amp circuit or power supply circuit. In most cases it is the amp circuit. More often than not, it is the zener diode and resistor that are bad. This would be preferable since the amplifier IC is very expensive and a total repair cost would be close to $200. The zener diode and resistor repair would be closer to about $100 depending on the rates of the service center.

I know this may not be the answer you were hoping to get, but it is the problem you have.

If you found this information helpful in making a decision on what to do with your stereo a FixYa! rating would be appropriate and very much appreciated, after all, it is the only reward we get for offering free help to people like yourself.

If I can be of any further help just reply to the post and I will get back to you as soon as I am able.

Good luck with your stereo, I hope you found this information to be helpful.

Your model will have two picos mounted on the same board with the 7 capacitors they will look like resistors without the color bands they will be F9B01 and F9B00 check them for continuity.

Convergence if distorted


Distorted is the classic sign of bad Convergence ICs and possibly the resistors that power them. Check the resistors right next to the ICs and replace both conversion ICs.

sounds like you either have a bad vertical deflection ic, or a bad resistor supply power to the ic. i'me not sure of the location, but panasonics usually put it in ic401.it is a ic with 10 to 16 pins all in a row. it will ne screwed to a small heatsinkthe making on the ic should start with laXXXX. x being numbers. good luck
