Question about Panasonic PT-51HX41 51" Rear Projection Television

Picture distored, wonky colours and bowed at the bottom [PIC Inside]

To help better I am going to attach a photo. This TV was manufactured in 2002 and has NEVER given us any issues. Just this morning upon powering up the TV viewed as it does now. Distorted picture, pictured bowed at the bottom and colours really messed up.

The video source is DVD, i grabbed the first one i could (LOL).

Anyways, just looking for a yes/no it can be fixed and possibly a cost.

Thanks in advance! :)

    Same issue here. Never had an issue with the TV and today my picture looks just like yours. I saw the response posted to your problem. Did you try this yet? Did it work? What is an IC and where did you buy yours?

    Turned mine on this morning and had the same problem as described here.

    I too have the same problem. However, I've been able to isolate the problem by covering the green projector (there's also a blue and red projector) with a piece of cardboard to get the picture back to a somewhat normalcy. I figure there's a connection between each projector and the independent circuit board each have. Will gather more information as I experiment more with transistors and switches.

  • 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Relatively easy to fix. If you can solder, you can probably fix it yourself. Look for a couple of large black ICs attached to a heatsink. They should be marked STKxxx. These are the convergence ICs. Try resoldering the pins first. If that fails, replace the ICs. They will be about $20 each or so.

Keep us posted.

The picture is showing a double image and is distored.


The problem you are refering to is more than likely a convergence problem. The convergence circuit in your tv is controlled by an IC (integrated circuit) stk392-110 and it makes the 3 colors (red, blue, green) line up/converge together to create a clear picture. You'll know when this part needs to be replaced because the picture you see is 3d looking and possibly bowed on the top or bottom or on the sides in any or all 3 colors.

Picture becoming distorted at the top/bottom of the screen is due to the convergence circuit going bad, and is a common issue with big screen projection TVs.

The convergence circuits will need to be repaired, which will generally require some soldering and ordering new parts for ~$75. If you want to get a TV technician to repair it then you will probably be looking in the region of about $300 for a repair.

Here is a link to repair guide for a Mitsubishi TV. Obviously a different model, but the convergence circuits are generally the same for most makes/models - this will give you an idea of the work involved to fix it: http://www.techlore.com/article/22530/DIY-Repair-Replacing-Convergence-IC-s-on-a-Mitsubshi-TV-Set/

Check the fuses 1007 & 1405. If they are blown in will cause an Arc.

can you post a pic of your screen so i can properly diagnose the problem as it could be either a pincushion or convergence problem. A picture would clarify it for me.
