Question about Panasonic PT-47WXC43 47" Rear Projection Television

Panasonic PT-47WXC43G TV, Turns on but I get 5 blinking lights

I own a Panasonic PT-47WXC43G Rear Projection TV that is around 5 years old.

Around 6-8 months ago I had to get it fixed for a convergence problem. After that it was running just fine up until just recently. When I went to turn the TV on the other day the TV sounded as if it was turning on but then I started to hear a clicking sound for a few seconds and then it stopped. The led power light blinks 5 times then pauses and blinks 5 more times, and so on, this continues on until I unplug the TV from the outlet.

I would just like to know if this problem is fixable, and if so how.

Any help would be most appreciated. Thanks in advance.

    How would I go about that? How or where would I check the power supply for voltage?

SOURCE: NO PICTURE, NO SOUND, TV TURNS ON THEN TURNS OFF

STOP THE PRESS!! I FIXED MY TV for a whopping $26.

I took a wild shot and purchased two STK392-110 convergence amplifiers from http://www.electronix.com/. They ship fast, placed my order on Tuesday evening after coming here and placing my comment. To my suprise the parts were in my mailbox on Friday. The parts were actually $12 but I also picked up a iron and a solder sucker.

So rarewish4us, If you're in the South Florida area I'd be more than happy to take that "JUNK" off your hands. LOL
If I were you, I'd give it a shot before you junk it.


Good luck,
Howie

This sounds like a main power board issue. After you unplug it, it will work? Are you planning on trying to service it or having it serviced?
Thanks,
Lee

Decoding the number of beeps may be possible with the owner's guide but this type of problem is normally due to a failed power supply.
These are often mounted on separate boards located in the bottom of your set and can be identified by the much larger parts you see on the board and possibly its relationship to the AC cord coming in. While these can be repaired, the cost of that will approach the cost of a new assembly.
Unfortunately, modern, more energy-efficient power supplies have some critical components that if bought cheap, don't last very long and frankly, 5 years isn't bad, I read of many dead within the first year.

Your symptom sounds like a damaged convergence IC.

You should be able to get a local service center to repair this at your house for between $350.00 - $450.00, If you want to repair this set yourself, I have some insturctions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.

When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board2.gif. 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.

Yellow blinking light


Panasonic HDTV are some of the best. It is very rare when a part in this TV set goes out. The most common issue is the lamp. A ballast board may also go bad with time but it is very unlikely.
If you never replaced the lamp before that is the first place to start or if its around 3 years old.

Replaced convergence chips, have new problem


Did you check the 2.2 ohm 2watt resistors? As often one or two will blow when the old ICs fail. The 3 blink error is indicating a problem with the convergence circuit still.
