Question about Panasonic PT-47WX49 47" Rear Projection Television

Open Question

Same problem with my Panasonic TV

Hey Sideshow,
So I'm having the exact same problem with my tv that you had meaning the blue ghosting in the picture. I tried to fix it via the convergence menu but it was impossible to get it right so I'm assuming I have to fix the IC's on my tv as well. My question is I've never done anything like this so would it be wise to try it myself or pay the estimated repair of over 200 bux to get it fixed by a professional? The tv itself cost me 300 from a family friend so I don't really want to spend as much on the repair as I did on the actual tv. Thanks for any feedback.

The convergence amps have most likely failed. That unit takes two STK392-110 (Sanyo) amps. For more reliability I'd have them changed using an STK392-150. They have a greater amperage and higher heat tolerance.
It's clearly a job that you want a qualified shop to do.. Call around and get some off-the-cuff estimates on what they charge to change out the convergence amps and tell them that you would prefer they use the 150's instead of the 110's.. They'll probably wonder how qualified you are. :)

SOURCE: convergence problem ,Help Please

Something is not right here. Is there any possibility that you can get the circuit designation (Rxxx) of the resistors that were "incorrect"? I am not aware of anything like this that can cause the "memory to be erased". The only memory in that area would be the factory convergence settings which can be modified from the service menu. Please try to supply the resistor IDs and I'll check on this.

Thanks,
Dan

The chips are located on metal heat sinks with fins and are side by side. They are black(about 2 inches wide by 1 1/2 tall) and should have the STK-392-110 number printed on them in white.

Depending on your level of skill at this kind of work you may be able to do it yourself---if you need step by step instructions contact me---I have them in Microsoft word---start to finish repair including what you will need to do it.

If you are not able to do the repair yourself now is the slow time of year for TV repair shops----It should be fixable right in your home and the repair takes about an hour--I have done hundreds of these sets--some shops charge 300-400 but I do lots of them for 200-250 total cost. Make sure whoever you get changes BOTH of the chips!

Shop around and if they say "needs to go to shop" keep looking; any good tech can do this right in your home.

I do this here for free so if this helps you give me a vote here. If you need direct help contact me.

SOURCE: When lining up convergance, green

hello the problem is down to the convergance ic, there are 2 big black chip that sit on metal frame called a heatsink they are usually located behind the tuner board on the right side of the tv,stk-110 may be the part number, also in front of the ic are some resistors and 2 capacitor at either end these will need to be tested ,
you have to desolder 1 end of the resistor so you get a proper reading on the mulitmeter, it's lot of work but if you can do it yourself it would cost about 40 to 60 pound good luck

regards
shaun

Hi! I am experiencing the following three

Hi Rafael,

First of all thank you for posting your question here at Fixya.
Please confirm if the brand and model number above is correct.
Blinking of the the LED (yellow and blue) at the front panel indicating that the lamp door cover is not seated properly. This cover will engaged to a micro switch giving the signal to the processor, once it is in open position, the unit will not power up and will experienced that kind of blinking error code. Go back to the lamp door cover and ensure that it is properly seat-in.
3D, 2D, red/green/blue ghost on the picture and letters means that the convergence circuitry gone bad. Symptoms is not connected to the light engine. The faulty parts is the convergence chips(IC). This chips are mounted on the large aluminum heat sink and starts with STKXXXX-XX (X means number). The most common STK chips used on Projection TV's is the STK392-110. You have to replaced them both on the board to resolve the issue(red ghosting). It is necessary also to check the resistance value of the resistors around its circuitry using the multimeter. For more info how to repair a convergence problem, watch the video below.

Projection tv won't turn on after replacing convergence & resist

STKs are static sensitive, your tv though, also has a digital convergence board that if damaged will cause any new ICs and resistors to fail. you need to have a technician repair this. This is why many of the DYs that seek help on the net would save money, simply by calling on a repair shop. Julio [email protected]

Red and blue ghosting,

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Problem with HD feed from satellite receiver

I just had my HD DTV installed this weekend, you have to leave it on 480p. I too purchased my tv in 2002. Per DTV, its an older model and you have to stay with the 480p to get the best possible picture. I have to admit, don't know what the 1080i looks like, but 480p is showing me a very good picture. Best I have ever seen on my TV.
