If you turn on your set and you hear a clicking noise, or a ticking sound. You most likely have a shorted Horizontal Output Transistor (Refered to as a HOT)

I would recommend that you contact a local servicer in your area and see if they can come to your house and diagnose the problem and give you an esimate for the repair. This can be tricky to diagnose and the potential for electrical shock is very high. So I would be careful if you wish to repair it yourself.

I have done this repair before and I think that you should be able to get a servicer to your home and repair the set for somewhere between $350.00 - $450.00 depending on the parts that are needed and the area in which you live.

I hope that this helps you with this issue. If you have any further questions or, if you wish to repair it yourself please post back and I will try to help you as much as I can.

Your symptom sounds like a damaged convergence IC.


If this is the case the power LED should be blinking 3 times when trying to power the set up.

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. 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.

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/ , 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.

Has audio, but why did screen go black?


since the self generated menu displays ok id say you don't have a monitor problem , could it be that maybe somehow it got switched over to maybe an "open" input port (example: hdmi-2) as this would explain things a bit , also when you tried the other tv did you use the same cables to connect it as the non working tv ? as that also would explain things

Convergence panasonic HDTV 1080i bbe hi definition


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,Pioneer 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

It is. And I hope you some cash set aside for this extremely costly repair.
I once had a rear projection TV and was told by the repairman that each of the 3 flourescent lamps run about $200.00 to replace.
Needless to say I did not get it fixed
