The 3 times LED code points to no fan rotation. There are 2 fans. Check the larger fan first, p/n = FBL12G12LS, located near the lamp. Even though that fan may be rotating, it may be slow.

you can wipe the inside of it with a dry cloth

If screen size is smaller, is the size changing when turning channels ? If so then you have to go into settings and change the aspect ratio to either Normal (then all channels will appear the same). If you choose a size then all the channles will appear that way. Your color wheel could be going out if the green color is not working or has problems "meshing" with the other colors. Hope this helps

Get a new repair guy. Actually, the TV is working fine, it just needs
convergence aligned for the 1080i mode. You need to find someone who knows
how to do it properly and if this guy didn't know that you have to align CRT
based sets specifically for all scan modes, he is not the "repair guy" that
you want to be using.


It wld cost you around $400 to rectify this.


Thnx.

Ur tv 100% have a problems known as a convergence picture peoblems.The tv convergence board it is dead,if any of the colors lines R,G,B mis alignments and u will not able to auto or manually to adjust any of the R,G,B colors lines to alignments any of them up.The tv convergence board must be replace like 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence picture problems.The tvs shops will cost u like $300-350 for parts and labors.

This is a common problem. Its called a convergence failure. You can get all the parts from www.TvRepairKits.com

Your TV will commonly have one or more of the following symptoms:
  • Screen Looks 3D
  • Colors wont align
  • Screen may look distorted
  • No Audio or Video

You can see some examples and find a fix here...

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.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/ , 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.

Are you using Component cables? Will it do 720p just fine from the xbox? Have you tried putting the cables in the same input as your cable box and seeing if it will do 1080i there? Some inputs will only do certain resolutions.

Thanks, let me know, we can definitely get this figured out.

Hi,
Have you tried adjusting the picture settings at all in the menu of the tv? First thing to try is that.
Thank you,
Lee

Panasonic... | Answered on Aug 17, 2010


suggest you check the signal source settings. Eg, if it is a set top box driving that input then check that device picture settings are set to widescreen (16:9) format.

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 projeciton 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 photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

in panasoni tvs each number of blinks reprents a genral ida of what is wrong with it so that the technician know where to look in this case it is the convergence ics nowyou can order them yourself but i do not recommed it as these are very sensitive chips call your local tv repair gys and youll ger up and running either that day or within a couple days,

Hi,
All that mess in picture is due to failure of convergence output chips in this tv.
Replace convergence output ICs (two ICs) to solve picture problem. Required ICs are available in Part Store, click the link to have price info.
Thanks.
