Most shops I know are crooked and make up stuff to squeez the most outta ya usually about half what the set costs. so are car mechanics. best thing to do is ask around for trusted repair shop .....word of mouth rules. any tech with half a brain can come to your house point to the parts within 1 minute...and should just charge a house call. good luck

PT-47WX53 47 in. Rear Projection HDTV Television

replace the DG board which is the small board which plugs into the A Board ( on the left side looking in rear of the set) The DG is the board which lays flat on top of the A board. You can get the A board and the DG board combined at www.tvrepairworld.com They may sell it seperately if you inquire.

I have a blue double image on my panasonic pt 47wx53

Your symptom sounds like a damaged convergence IC.

You should be able to get a local service center to repair this at your house for between $350.00 - $450.00, If you want to repair this set yourself, I have some insturctions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.

When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

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. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Yes you can get replacement IC STK392-110 convergence ICs at the following link and they provide free instalation instructions with pictures. The Ics are located on the board on the left side attached to a large heatsink. You will need to replace both ICs heres the link.

crsheidt,
I am having the same problem.Terryfic gave me some good advice I am the process of taking. The service manual will help you locate the convergence IC circuit board so you can remove it to replace the IC`s. If you need I can send you a copy of the location picture from the service manual.I recommend you contact Terryfic for exact advice.

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.

Was this help full.

PT-47WX53 blue convergence PROBLEM

Sounds like you have a blue foldover in the convergence. Since tv has been worked on it could be bad ic, maybe not original, generic. I would say if you can open set and look in, look for the blue it should be marked. look for a loose connection. If you can have someone to gently tap around that blue amp and see if it moves are go away, it might be a simple loose connection and needs soldering. If not then my have to change ic again. Becareful cause set would need to be on to really check. Hope this helps.
