Question about Panasonic PT-47WX42 47" Rear Projection Television

1 Answer

PT-47WX42 47 - Red color becomes prominent and screen goes blank when changing channels

My TV has started to act up lately. It is a Panasonic PT-47WX42 47 and we have had it for 5 yrs. When we turn it on, the red becomes very prominent., and sometimes when changing between channels,(especialy between analog and HDTV channels) the screen goes blank and comes back after a little while. The verizon fios screen menus which are blue, becomes darker and the whole screen is darker. Any help will be great.

Do a reset to this TV, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

SOURCE: Picture doesn't work..Panasonic 47 inch TV PT-47WX42

Dood, if you really needed a new mother board for your TV the biggest problem on your hands would be finding the replacement.  The motherboard is so easy to remove it would make you laugh.  I think it has four clip bridges and four of five screws.  You seperate the clip bridges, take the screws off and maybe take a picture of the cables so you remember where to plug them in and you're done.  Like I said, take a snap shot so you dont forget where to put your cables back in.

SOURCE: panasonic pt-53wx53g tries to turn on but goes right off

That is indicating that the convergence circuits have shutdown the set. You will need new Convergence ICs. They should be STK392-110 or STK392-120 either number works the 120 being the better chip. I will post a link where you can get the new ICs and they provide step by step instructions with pics so you can do the repair yourself. You will find your IC numbers under the section titled Convergence ICs just click on that and you will find your STK numbers.

SOURCE: I have a problem with my Tv pt-47wx42

Your symptoms sounds like a damaged convergence IC.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

If your colors line up in the middle of the set and at the top but the picture is concave then you may have a faulty component in the pincushion circuit. When this circuit fails the picture will have an hourglass shape to it with black in the middle on the sides, or you will see square objects as hourglass shapes. If it is like you described and it is in the top and bottom, you may have a problem in the top and bottom pincushion circuit.

You stated that the charge will be $80.00 to diagnose this problem, I would ask if the diagnostic applies to the repair, if you choose to repair the set.
I have seen this type of repair run from $250.00 - $350.00.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon and it should only add the cost of the part to the repair.

I hope this information allows you to resolve this issue.

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?


Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

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.

The color goes out on my panasonic PT-47WX49E TV.


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common 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.

Blank Screen - Panasonic PT-50LC13-K


Hey Ben, The TV is alerting you it is about time to change your light bulb, it will keep on doing this until the light bulb just dies.
Order your Bulb via On Line at any of the places, there are different prices, but average for the authentic one with the chasis included is @ 260.oo and only takes @ 5 days to get delivered. You can save up to 140.oo if you just order the pure light bulb, and go the extra mile changing it, I just explain someone how to about it, only takes you 30 mins. Good look, I hope I get help for my problem too.

Convergence issue


You can go back to factory settings by pressing and holding the ACTION and POWER buttons on the TV while it is on. A CHK screen will appear and when it does release the buttons and then power the set off then on again. This had reset all settings back to factory conditions. You will have to reprogram any channels into memory after this.

On the front of the TV while it is on, press on the ACTION and POWER buttons at the same time and hold them for about 5 seconds until the screen goes blank and comes up with a diagnostic screen. Once that happens release them and press action again to clear the diagnostic information. Now your TV is se back the way it was brand new so you will have to proram the channels back into memory and apply your color,brightness,hue etc..settungs as those have all gone back to factory as well.
