20 Most Recent Panasonic PT-47WX42 47" Rear Projection Television Questions & Answers

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.

Does the TV have a plug connection I think is called DVI. There is a DVI to HDMI adapter that also needs an audio connection on TV to work. Other option is audio and video rca cables. You may also need to change input connection to correct source, as it may not be auto for connection

Not sure what you are talking about, this set uses two of the STK-392-110 CONVERGENCE IC'S. There are no transistors that go to individual pins on those chips directly---you are talking about the light blue resistors that do go to individual pins---most are 2.2 ohm and 1/2 size and those are about the only ONES THAT EVER FAIL--HAVING FIXED NEARLY 200 OF THIS EXACT MODEL SET, never seen more than one of the 2.2 ohm resistors bad---If you want to make sure each is the correct value, Google for the full service manual by model number, no one carries those number to value with location numbers in their pockets, IF ANY OF THE 2.2 were bad set would shut down and constantly blink 3 blinks at the power light.

This model has to have 1080 signal connected and will then auto select it if present, no way to manual switch modes.

Your TV should automatically switch to 1080i if the source input is in 1080i format. Also, since your TV does not have HDMI, you must use the component 1 or 2 inputs (using component cables) for 1080i source material. You cannot get 1080i from composite or s-video inputs. You should be able to switch to the component inputs using the remote or the front control panel using TV/Video button.

The 3 blinks is indicating the set has shut down due to the convergence circuits. You can get the convergence repair kit for your model from www.tvrepairworld.com the kit contains the parts and the CD with repair instructions.

The blinking is an error code. How many times is it blinking before it goes out?

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

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. In some cases the TV will also not show any video. 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. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.






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.

The blinking light is a error code, unplug set and turn it back on, if light blinks look carefully at it, usually this set will blink in a sequence.

3 blinks, pause or 5 blinks pause and it will continue repeat this error code.

Let me know if can identify number of blinks and I will assist you.

Look at my record here, I know what I am talking about.

If you have gone into the customer menu and CONVERGENCE is skewed and will not adjust:

One or both of the two STK-392-110 convergence chips that this set uses are bad.

The chips are about 2 1 /2 inches wide by 1 1/2 inches tall and are black in color. They are mounted on metal heat sinks with fins and are side by side--they will have the Stk-392-110 number printed on them in white letters.

If you locate them take a good look at all the light blue resistors in front of them--most are marked 2.2 ohms---look for any that are white or discolored in the middle---if you find one or more YOU HAVE FOUND YOUR PROBLEM.

BOTH chips and any bad resistors need to be replaced and the set adjusted. If you can do this repair you can save a lot of money as you can buy both chips (a pair) on Ebay for about 12 dollars plus shipping.

I have start to finish instructions for this repair on this type of set.


If you cannot do this repair yourself, shop around your area--most shops charge 300-400 for this kind of repair--I do them here for 200-250 and have done hundreds of them.

If they say it has to go to the shop--keep looking as any good tech can do this repair in your home in about 1 hour.

IT may be if the set has not been "serviced" in a while a cleaning issue. If picture got gradually darker try something easy first.

Unplug set and remove back cover.

Locate the three large black lens in set based on model number, use either a lens cloth or a paper towel with glass cleaner sprayed on it and clean all three lens.

The lens are the light source for your picture and if dusty the picture will be darker and duller looking than it should be.

If this is your problem it is a good idea to clean the lens at least one time a year.

Let me know if it works OR IF YOU HAVE QUESTIONS.
