Panasonic PT-53WX42 53" Rear Projection Television - Answered Questions & Fixed issues

try contacting the manufacturer. without more information about the make and model that's the best I can offer.

Repairman needed. If it was like this when he "fixed" the convergence issue, the job was obviously not completed.

Unless you are familiar with TV systems, this is best left to a professional. Rear projection systems typically use three separate image sources (red, green and blue) to display the picture. If any of these sources is misaligned, the convergence problem arises. It may be something as simple as a bump while transporting it or some loose screws but given the voltages in the back of TV systems, it is much safer to get a TV engineer to make the proper adjustments for you.

your convergence amps is shorting out 1 at least

The model listed is only HD (if it has that) via the HD component input on the rear---it may only have one HD input.

If we are talking about change where it looks 3d or words etc are outlined in red or blue that is convergence--have some more info for me?

Check your hori out put transistor NTE2973 & 1200pf & 2kv capacitor next to it,most of the time this is what is bad .
ThankYou for using FixYa. Have a Nice Day.

unplug tv check the fuse and the rating on it,.see if filament inside is burnt

I do not think we will get a response from person asking but you are correct, number of blinks indicates where problem is, the two most common are either a sequence of 3 blinks or one of 5 blinks.Hard to help unless blink count is known.SD TECH

The model number is not a sony, what is the model number on the back if it is Sony?

Hello,
Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement. Hoping this will help in solving the problem...

The convergence ICs are ready to fail. Replace both convergence ICs and check the low ohm resistors as they will most likley need replacement also. You can get the PT47WX52 convergence repair kit which fits your model from www.tvrepairworld.com whch has the ICs, Resistors, heat sink paste and the CD with repair instructions.

Hello,

You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections.

The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad.

This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced.

The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this IC is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.

Hope this will help in solving the problem.......

You need to check the hori output Transistor and the 2k capactior small blue cap,it feeds to the Transistor.If they are OK then Replace your STK ICs they are Big Black ICs and will have PN on them,example STK392-110
Mats has ICs 1-800-628-1118

Picture colors lines R,G,B mis alingments,have colors shadows pictures or 3D pictures look alike?Yes.The tv convergence board is dead,the board require changes 2 STK convergence ICS and some or all of it resistors too.To fix the tv convergence board.U must have tools like a soldering iron,a desoldering pump or a roll of desoldering braids and also can do soldering work?Yes,tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a convergence kit belong to ur tv model and make to repair it ur self.Or the shop will cost u like $300-350 for parts and labors.

Thats a convergence failure when the led blinks 3 times. Your model uses the PT47WX42 convergence repair kit available from www.tvrepairworld.com the kit contains the parts and the CD with instructions for the repair.

No, there is no bulb in your set.

If you try to adjust convergence with the flash focus, perfect focus, (depending on the make of your set) or by manual convergence and the lines will not line up or even move. Your symptom sounds like a damaged convergence IC.

If you want to repair this set yourself, I have some instructions 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, heat sink compound, and some basic soldering skills, you can repair the television yourself.
*** VERY IMPORTANT NOTE***

If your set is not producing a clear picture and the colors are not lining up, do not continue to watch the set as this can lead to further failure and possibly damage the individual CRT's in the set.

I have repaired hundreds of these sets, so if you have any questions after reading the following, please reply to this post and I will help you in any way that I can.

With that aside I have some support suggestions that I have put together that may help you make an informed decision. 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 instructions below that will be a help to you. While it is not a very hard repair, this repair can be a bit tricky How do I tell if the IC's are damaged? Since you cannot look inside of an IC, you will have to locate some of the components in the area around the convergence IC's. You may be able to see some resistors that have changed colors or you test a resistor and it no longer reads the value marked by the color bands or the printed value. You will have to replace the IC's and the supporting components.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 insulator for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag. Where are the IC's located and how do I find them?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.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.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.aspxAnd their phone number is a 24-Hour Order Desk: (800) 274-4666I 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/ , they do carry OEM or better parts. When you order from them you will get a kit with instructions on how to do the repair, step-by-step. 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.

change your tv mainboard with new one

most of them have the on screen settings, and if this is not working correctly there will be on some but not all a few plastic dials on the main board inside the case that is the factory adjustment, and if your does not have these inside it, then it will be the either the projector lamp or a bad circuit board.
