Question about Panasonic PT-47WX53 47" Rear Projection HDTV

1 Answer

Sudden blue shift

While watching, the blue video component on our PT-47WX53 suddenly jumped about 2 inches to the left, almost uniformly across the screen. Attempting on-screen correction, we found the image could not be shifted all the way back to the center. Adjusting as far right as possible results in distortion.

Given the other answers I've seen here, I'm guessing the solution will involve replacing ICs. If that's the case, I'd love to hear any thoughts on whether I should use the STK392-110 suggested by Slinteriors, or the C5AA00000203 suggested by Terryfic.

If anyone thinks the problem might be something other than ICs, I'd greatly appreciate any ideas you'd care to put forward.

Thanks for any help you offer!

Use the 180's. I've just replaced mine and everything runs fine. I've heard they run cooler.

Hello twisttolife,

What you have lost is horizontal deflection, this is caused by loss of the horizontal drive signal to the yoke transformers on the CRTs, for all three of these to fail at the same time is not likely so what I think is that the drive amplifier may have malfunctioned. To check this you will need:

1) schematic diagram or service manual (to determine the proper voltages and signals on the deflection board)
2) Multimeter (to measure the DC voltages on the components of the deflection board
3) Oscilloscope (to view the waveforms on the deflection board)

With these three pieces of test equipment you should be able to troubleshoot this problem.

Now if you do not have this equipment and what to take a chance at a blind guess, and just replace a board, I would suggest replacing the deflection board, this board usually contains the flyback transformer, the Convergence modules (which can cause this problem also), and the connections to the yoke transformers.

I hope this helps,

Picture shows only about a 2-3" blue,green,or red vertical line down the middle


If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Uh oh... the colors are curved and wacky


replace the amplifier IC chips for the convergence.  part # stk392-???  could be from 040 to 120..  90% chance that'll fix it.
