Your Set is going into shutdown mode due to the convergence section of your television. Thats what 3 blinks mean. It could be just the Convergence ICs and resistors or you may need a new Signal board TNP2AH035 Let Me know if you need further assistance with this problem.

If your Panasonic Television is blinking 3 times then you have a short on your power supply and the most likely suspect is your convergence IC’s.
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?
When looking at the area around the convergence IC’s you see some resistors that have changed colors, or you test a resistor and it no longer reads the marked 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 insulation 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, and your will get a repair kit instead of just the IC's.


I hope this information allows you to resolve this issue.
I am doing this for free.

Please Note: If you cannot rate this post with the highest rating, then please do not leave any rating. I am doing this for free and I do not think that any rating other that the best is needed.

SOURCE: I have a Panasonic HDTV Projection Monitor model

Three blinks is short protection in this model.

98% chance one of the protect resistors around the two STK-392-110 convergence chips is bad.

Good news here----total parts cost would be under 25 dollars on EBAY. I use a seller there.

I also have start to finish, step by step instructions for this repair in this set.

They tell you everything you will need and how to do the repair.

Let me know if you want help or the instructions--I can tell you how to look to see if the protect resistors are bad.

This is a very common problem and I have fixed hundreds of these sets with this problem.

If this information told you something you did not know, rate this solution as very helpful as I do this here for free.

If you need more help or want the instructions let me know, we will find a way to get them to you for free.

Have a shop look at it, there is a power relay that either is causing this or something right around it is, seen this about five times over the last ten years in Hitachi sets.

I have RED verticle lines all the way across the screen fro top to bottom 10 minutes after I turn my Panasonic PT-52LCX65 TV on. Is there a solution?


Hello
Check and replace the main filter capacitor in the power supply section. Replace all of them in the secondary section of the power supply too. The problem is due to insufficant smoothing and regulatio fo the power supply section. If main smoothing capacitor gets value deveoped, it won't supply enough voltage to the switching section, and switching section also will go inefficient. Replace all of them. It won't cost not much. OK.

I have a panasonic projection TV, PT-60C13 that will not turn on. Upon pressing the power on button, the button flashes green many times, then flashes red five time then one orange flash. This red/orange...


Hi,

The most common cause of Panasonic Rear Projection LCD TVs not starting is bulb failure. The PT-60LC13 users manual gives some help in translating the LEDs on the front of the TV.

If the TV worked normally for a period of time (months or years) and won't start, the most likely cause is bulb failure. There is no way to measure the bulb, sometimes the bulb is visibly damaged when it fails. Remove the Lamp Assembly and look at the bulb.

If there was an On-Screen Lamp Replace warning and TV won't start, bulb has failed.

The first step with all Panasonic Rear Projection TV "No Picture" problems is bulb replacement. If that does not remedy the problem, get a technician, there are no user serviceable parts. Guessing if the ballast, power supply, controller board or optical engine is faulty is not practical.

The Panasonic Lamp Gallery shows all Panasonic models and Lamp Numbers. There is also a link to Panasonic DIY bulb and lamp replacement.

My 1080i has a triple picture, can you help?


Hi,
It definitely can be fixed the IC chips (called STKs) that line up the images from each picture tube are failing.Sometimes a fuse or resistor go out along with the chips. The parts would cost around $100 + whatever labor charge if you hire someone.
