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

1 Answer

Wavy dark lines

I replaced my STK392 IC's w/-180
I did a good job soldering
I still have wavy lines on the screen
The convergence is fine now
Do I need new tubes or is it some caps that are now out
I can replace the caps, but if I need new tubes I'll junk it
I will need a service manual to look at the schematics

    Where do I buy the replacement parts c7036 and c7054? And, will you send me a schematic as well? Thanks

  • Lonz122156 May 11, 2010

    Yes the lines are dark and they are across the width of the screen, the lines jump and move a lot.



    I can sometimes see a convergence problem at the ends of the lines

    Check c7036 & c7054 on the A board, I have replaced them and the picture came back clear, they are located looking from the rear of the boards it is on the left side front. If you need the schematic you`ll have to send your e-mail address.

My samsung projection tv has blue wavy lines on top of screen, I adjusted convergence, the blue will not line up horizontally, is there a inexpensive solution?


It means one of the chips has a bad section inside it, both chips and maybe a resistor near them will have to be replaced, involves soldering as each has about 18 pins soldered in

Check with TVrepairparts.com who sells some kits for this by brand and model number

Wavy green lines and offset during convergence calibration


There is whats called a convergence IC that is going bad inside this TV set. There is only one for all three tubes and the IC number is STK 393-11- and can be purchased here http://www.electronic-repair-kits.com/STK393-110.html You will only need to order one. If you are handy and can solder this should correct your problem. One very important thing is, before you reinstall the new convergence IC, make sure you use a good coating of heat sink compound on the back of the new IC. If you do not, the IC will fail within a short time frames. Only if you are good with a soldering gun should you attempt the repair. If you are not, this repair should run you about 300 bucks or so. Also if you are handy, there are seven capacitors that go bad inside a board called the DM board. These will go bad very soon so while your in there these should be changed as well. If you need info on how to change these capacitors, let me know and leave an e-mail and I will send you the pictorial on how this is done. the IC change you will need to find that, but I do have a service manual if you need one also to help you along if you can follow the schematic. Good Luck

The colors in my tv are overlapping and picture is wavy that cannot be solved with adjusting the manual converge function and got worse when I tried restore manufacture settings


Bad STK392-120 convergence IC. You need to replace 2 both and also check feedback/return resistors. Convergence IC is located on large signal board with a big heatsink. :)

JVC AV-48WP30 convergence drifting after IC replacement


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

Red Wavy lines running across the screen...


Yes - - that indicates one of your convergence amps have failed. That unit takes two STK392-110 Sanyo amps which I personally would replace with STK392-150's for greater reliability. Also check all of the return resistors in that circuit 1.5 ohm 2w and feed resistors 3.3 ohm 1w all are flameproof. You'll likely find that one or more of the return resistors are bad, with suspecting the red is the failed amp check in particular R846 for change in value or open.

Vertical hold wavy then no picture and power lite flashing


you are probably having 2 problems. on that model there was a jumper wire the fed the convergence amps power and would get very bad cracked solder. and casue some fuses to open on the main deflection board. if that is there i would recomend replacing the 2 convergence amps(stk392-110) and open fuses. but your wavy lines are going to be all the 10mf16v surface mount capacitors inside the hyperunit(figital scan card) it is a square metal case located behind the input board.*****it is soldering in with 4 tabs on the bottom side of the signal board so be careful not to just start pulling on it to get it out*****

The STKs are common and if you have an experienced electronics tech around they can replace them for much less money but the tech must have advanced soldering and IC exchange experience.

The STK ics, two of them, can be purchased on line for around $20 to $40 each.

http://www.partstore.com/GetModel.aspx?MfgName=Toshiba&BrandName=Toshiba&ModelNu...

Partstore has two models available - one for around $40 and another for around $55.

The part number is STK392-110 and if you google you can find them for as little as $6/each but I don't recommend the cheap ones as they are not reliable.

It takes a good tech around 3 or 3 hours to take the old ones out and solder in the new ones. Also, it is likely one or two resistors are burnt and will need replacing as well.
