Usually what happens is that the convergence IC goes bad or the fuse going to the convergence ic goes bad. Pico fuses they are called sometimes open up. You may want to open it up and pull the board out and check the solder connections on the convergence IC. Sometimes these get fractured or cold soldered and aren't making connection to the PC board.
Let me know if you feel comfortable with pulling TV chassis out or pulling the board that has the convergence IC on it out. Then you can resolder convergence IC OR replace it.First thing i would do is check to make sure there is between 22vdc and 25vdc on the fuse or the convergence IC. Let me know if this helps out any.... Sincerely HDTV GURU JAY

Picture not in focus


Devices: All projection TV's (HD or analog), especially Samsung

If its a Samsung HCN653W (or similar model), the first thing to try is the menu option named "Magic Focus", which tunes the set's focus.

Otherwise, it sounds like a job for a convergence. Perform a convergence procedure on your TV, and if the problem recurs within a few days/weeks, then your TV's 'convergence amplifier' board (aka "convergence amp board") is starting to fail.
This board may fail completely, in which case, your convergence procedure will fail to improve the picture.
A "convergence procedure" can be performed entirely by just using the appropriate setup menu option and your remote control.
This board may partially fail, in which case your convergence procedure will properly converge the Red, Blue, Green colors on just part of the screen, whereas a properly functioning convergence amp board will allow complete convergence of the colors across the entire screen.
Your TV's convergence procedure instructions will be found in your TV's Owners Manual.
At least one Projection TV manufacturer recommends that the consumer perform a convergence procedure every 30 days, but most TV owners find that excessive, and might only do one when (a) there's an evident color convergence problem in any part of the picture, or (b) once every 3-6 months.

How-to video: www.youtube.com/watch?v=esk4nYZKFcg
how-to instructions: www.ehow.com/how_2034880_perform-convergence--tv.html


cost to you: $zero
.

If the convergence amp board is bad, cost for a service call would be $300 (USD) plus $100 for a new board plus 50% markup on parts = about $450 (USD)
Cost to order a new board online: about $100 (USD) + shipping + sales tax.
Alternatively, if you can solder/desolder STK's (Power Amplifier Integrated Circuits), one can repair a convergence amp board for as little as $30 (USD) or so.

Convergence issues


Your TV most likely has a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

0667c5f.pngSOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Need to know what convergence chips are in Panasonic PT51HX41E


your model has two STK392-110 CONvergence Cs, you will also most likely need at least a few of the 2.2 ohm 2watt convergence resistors. I am posting a link to the actualrepair kit for your model which contains both Convergence ICs and all 6 of the convergence resistors and they send instructions with pictures that show how to do the repair.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed.
