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.

    Thats possible have you gotten some bad ICs or if they were shipped may have been dropped during handling. ICs are static sensitve so even a small drop could hurt them.

My panasonic cinemavision hdtv is showing double vision. How can this be fixed.


This is likely a convergence problem and if model number indicated here is correct set would need to have both of the stk-392-110 chips replaced and the set adjusted.

Let me know if you have questions.

We have a PT-47WX51CE panasonic cinemavision hdtv 1080i and the colour is off. We see separated mainly green and magenta and the picture is warped with some lines.


Hi,
All that mess in picture is due to failure of convergence output chips in this tv.
Replace convergence output ICs (two ICs) to solve picture problem. Required ICs are available in Part Store, click the link to have price info.

Panasonic PT-47WXC43G green ONLY is bowed on bottom and top


Hi,
It still convergence chip problem, check big resistors nearby these chips that would be open or devalued and causing problem, specially in green convergence area, your green tube/ gun is just fine and just not getting convergence output signal to show correct image.
I would suggest to download service manual copy of this tv for small fee from any website and fix the issue with schematics help.
Thanks.

Bad color then no power on 51'' panasonic cinemavision


Check the power light for blink code--usually if this model shuts down the power light will blink in a sequence--3 blinks a pause and 3 blinks is short protection--usually means a convergence circuit problem.

Let me know what you find--I am here to help.

if this helped you rate this solution as I do this here for free.

Your TV most likely has a Convergence Chip 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.
