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

1 Answer

My PT-47WX49E was working fine yesterday, as it has for the past 7 years. Today, just won't turn on. No red light, no nothing. When you unplug from the power strip and plug directly into the outlet it makes a click like it would when it would turn on - but does not.

Your symptom sounds like a damaged convergence IC.

This is a common failure for this particular television. The blinking lights on the front of the set will 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 sinkMy PT-47WX49E was working fine yesterday, as it - 2.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 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.

TV won't turn on power light flashes 10 times


Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

I looked up your model number. You particular machine allows for wash with the lid open. You nothing happens. On that case I would check the motor capacitor.

Pt-47wx49e service mode


It sounds like the convergence amplifier IC for the red crt is at fault. To check this, go into your user menu and pull up the red convergence. Try to move it up/down or side to side(it doesnt matter). If it moves up and down, then the vertical amp is working. Likewise if it moves side to side, then the horizontal part of the IC is working. If it dosen't move at all, or only moves up/down or side to side, then the IC is bad. There are 2 large IC's on the chassis, mounted to large heatsinks. They have STK392-110 or some variation of an STK392. If yow feel that the IC is bad, change the ic BEFORE you go into the service mode, as you wont need it if the ic is bad. To get into theservice mode: 1 make sure tv is in cable mode 2 set sleep timer to 30 minutes 3 tune to channel 124 4 use volume down on front of set to turn volume all the way down. ( writing will appear in the top left corner). 5 use remote control and press the power button. 6 the 7 button on the remote will put it convergence mode. Good Luck!
