Missing red composite signal on panasonic pt-47wx52cf


Check your jacks and cables.

The RED jack is either (1) left or right channel AUDIO signal or (2) the RED color channel of an RGB (Red, Green, Blue) COMPONENT video signal.

Yellow is the COMPOSITE video signal.

I can't get the 3 colors to be one picture - I've got shadowing (or triple picture)


Set will need both the STK-392-560 convergence chips replaced===several sites sell kits with all the parts needed by brand/model number with instructions.

Picture settings


settings are not likely to resolve a "yellow" looking screen.

Go to an unused video input or turn color all the way off----the screen should be gray or black and white looking.

What this really suggests to me is a total or partial loss of blue--the set has a red, green, and blue picture tube---a loss of blue means red and green=yellow.

You can peek inside with the set on and see if all 3 lens for the tubes are lit equally bright.

Let me know what you find (press make comment on this page) and depending on what you find I may be able to suggest something to try)

PT-47WX52CF Shuts off automaticly then 3 flashes


I know what is wrong--3 blinks is short protection--

it means 98% chance one of the two STK-392-110 convergence IC's this set uses is shorted.

The chips are side by side (see photo) on metal heat sinks---there are about 12 light blue resistors in front of them marked 2.2 ohms---I bet if you locate them you are going to find one discolored or white in the middle.

I have start to finish, step by step instructions for this repair--shops get 300 or more but you can buy all the parts on EBAY for under 30 if you think you can do it yourself.

If you want the instructions and source for the parts let me know and I will provide them for you.

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

PT-47WX49E Blue and Yellow Shadows!! Help me


Have a qualified repair shop come have a look and give you an estimate. If it's the optical block it's probably not worth repair.

Panasonic PT-53TW53; Red shadows appear and then the t.v. shuts down.


The convergence output IC's have failed. Only fix is to replace them. These are large amplifier IC's bolted to heatsinks and have a high failure rate in all projection sets.

Red horizontal convergence PT-47WX49E


converge outputs getting tired or limiting resistors opening up. adjusting this incorrectly will make the situation worse keep in mind that overdriving these chips will cause a fold over of your image when you see this carefully adjust in the opisite direction as you may be overheating the outputs
