My 7 year old panasonic hdtv rear projection tv started showing a double image  2 days ago. The red color is also a little too pronounced. I recently had high  def service added to my satalite service. The double images started all of a sudden. Any information would be appreciated.

Thanks

Hello,

Does anyone know how to fix this?

Is it serious and expensive thing to repair?

Any help will be apreciated!!

thanks in advance!!

Typical convergence problem.  Since you left no model number, all I can recommend is you open the set and find the two large black rectangle IC's, about 2" by 3",  mounted up against a large metal plate, and they start with the letters STK and have several numbers following them.  These are the convergence correction IC's and are soldered into the printed circuit boards.  If you have some experience soldering and unsoldering on printed circuit boards, you should have no problem changing these parts.  If you do not have any experience, I would have to guess, since I do not have a model number, this will run you between 300 to 400 bucks to have a pro repair it for you.  If you think you can handle this repair, feel free to ask any other questions about this repair.  And please include a model number.  Good Luck.

Thank you very much Larry.

The price you told me is in the case when I will call technician?

I think I would be able to replace these parts, the only think I dont know where to buy them? and how expensive htey are.

I have seen on eBay a lot of similar TV as mine, they arent worth more then $250...

I just want to find out if this repairing does make sense..

maybe it's better to spend around $400 and buy much newer TV..??

Could you tell me where to find the parts, please?

thank you

Find the part numbers on the parts. Like I said they will start with STK on them, then most likely a 392, followed by three more numbers.  Then go to mcmelectronics.com, and enter then number on the IC.  These IC's are about 15 to 20 bucks for the original Sanyo IC.  I know you can go on-line and buy the IC's for about half of that, but the only problem is, their not original Sanyo IC's. they are whats called aftermarket IC's.  Yes they will work, but they do not have the same specs the originals do, and they can blow out very easy.

Thank you very much Larry,

 I decided to try (nothing to lose - I found on eBay TVs like this costs no more then $250 so that would be stupid call technician and pay even more), I ordered online parts, I bought iron solder and in around 2 hours my tv worked properly again. Now is about 2 weeks after this and still works, so I hope it will be working for long time... ;)

 thanks for advise

(I spent about $35 only)

Great news! Glad you fixed it.

Larry (or anyone in the know),

I have a similar problem with my 2004 Panasonic PT-53WX54J.  The only difference is that mine has blue sort of 1/8 circle like rising sun shape on the bottom part of my TV.  Is this also a circut convergence IC problem?  If so is this easily repairable if I am comfortable with a soldering iron?  What parts would I look for and need to order?  Thanks for your help.

I think I may have a similar problem with my PT-47WX49E, the picture looks warped in the green and the red and blue are way out of aliment as well. I tried to power down completely (unplug) several times, but nothing changed. Mine also happened all of a sudden, one night it was fine and the next morning it was messed up. Is this fixable by the same method above?

October 14, 2008 8:56 PM updated: October 14, 2008 8:56 PM

yes replace the convergnce IC's and find the bad pico fuses in the power supply and you should be ok, BUT if you use cheap parts you will get cheap performance.you will also need solid soldeing skills.

I may have a convergence problem with my six year old PT-47WX49E. The picture images looks haloed in green and the scrolling green text on the screen's bottom are out of aliment as well. Sometimes the picture slowly goes back to normal, but migrates back to the original problem. Is this fixable by repairing the convergence IC's?

My PT-47WX49E TV may have a convergence problem. The picture's images looks haloed in green and scrolling green text at the screen's bottom are out of aliment as well. The problem on occasions goes away, but slowly returns.

Is this a convergence IC problem?

October 18, 2008 7:05 AM

sure sounds like a convergence problem but a photo would tell me for sure.

Hello, my pt47wx49e has the same problem, I went directly into the serviceman menu and completely messed with it (I should have surfed a little bit more boefore going there) now I'm planning to change the STK's and components around, but before I do that I guess I have to bring all values within paramenters, does anyone have the right parameters for the serviceman menu that can please share? Thanks.

PANASONIC:

Panasonic TV's after 1996 can be set to "Serviceman Mode" with the
following remote control sequence:

First, select the SET-UP icon and select CABLE mode.

Then, select the TIMER icon and set the SLEEP timer for 30 minutes.

Next, press the ACTION button twice to get out of the menus.

Now, change to channel 124.

Then, adjust the volume to minimum (0).

You're almost there - Hit the VOL down button on the TV itself (not on
the remote) and a red "CHK" should appear in the upper corner.

Now, if you press the ACTION and VOLUME DOWN buttons (again, on the
TV, not the remote) you will toggle between AGING and SERVICEMAN modes.

Select Serviceman mode. The POWER button on the remote control will
select one of the five Serviceman Adjustment modes.

The modes are:

B - Serviceman VCJ SUB Adjustments. These include sub-tint,
sub-color, sub-brightness, sub-contrast, colorkiller/ABL/gamma,
audio and video adjustment, and vertical size.

C - Serviceman VCJ Cut-off adjustments. These include Red, Green
and Blue cut-off, red and blue drive, automatic fine tuning
(AFT), RF AGC (RF gain control), horizontal center, beam limit,
etc.

S - Serviceman Options Adjustments. These involce the PIP and
clock.

M - Serviceman MTS (Stereo/SAP) adjustments.

CHK - the mode you first entered. Normal picture and sound, lets
you check things over and still have a hotkey into the
service menu.

There is one more adjustment that isn't in the five modes, it's
global. When in either the yellow or red CHK mode, you can press
RECALL on the remote control to enter the purity firld check mode.
This lets you select a pure white, red, green, or blue screen. A
good thing to walk away from if you just want to temporarily freak
out the floor manager, but it will be fixed as soon as the TV is
turned off. Oh well.

To get out of Serviceman mode, press ACTION and POWER on the remote
cimultaneously for at least 2 seconds. The TV will momentarily
shut off and then comes back on.

Larry,

I've attached TV Screen Image a photo per your request. I hope it helps you identify my problem and offer a possible fix. (Please see image below the blank frame)

 Thanks,

if you replaced the IC's for the convergence, then there is an open resistor or pico fuse on the power supply somwhere. both IC's should feel hot to the touch.

First: Great site. The help is much appreciated. I, like many others, was having a problem with a 47 inch panasonic (PT-47WX49E). The convergence just wouldn't move enough.

I replaced the ICs and now the picture looks fantastic for DVDs and standard definition TV.

However, it is all screwy for HD signals (only) - same issue. when I am inputting a signal from the HD cable box, the convergence shifts and bows out to the side so far that I cannot adjust it enough. Is this a software fix that can be done in the service modes (if so, how?) or is it a hardware issue?

Thank you!

March 5, 2009 3:35 PM

I just replaced the convergence IC's with STK392-180's. The picture is perfect now but the TV powers off after a few minutes and it won't come back on unless unplugged. Then it does the same again. Can someone help? My guess is that I need to replace a fuse or resistor but I have no idea how to find which ones.

July 3, 2009 7:04 PM

My 1996 Panasonic projection tv pt-56wxf95a will turn on for a couple of seconds and then it shuts off before the screen even comes on. What is wrong with it so I can save up money to fix it?

July 3, 2009 7:20 PM

one question is the front light blinking after it shuts off? if so leave your e-mail address please!
