Remember Me? What's New? Results 1 to 15 of Thread Tools Show Printable Version. It turned off, then the red LED flashed seven times, continuously. A google search found a large number of people with the same issue, but this was on '08 built TV's. After doing so, all came good. It was actually a thread on this very forum, but it was a slightly different TV model. Issue is, for every person that replaces this part and gets it to work, there is another bloke who does the same and it doesn't work.
Apparently, the seven blinks can relate to a few boards. How do I test to see which board it is? On a side note, which may be related, the fan directly above the possibly faulty board has been noisy for a while. I have cleaned it a couple of times, but it always remains noisy. Could the possibly faulty board have over-heated from a dodgy fan?
Thanks for any help. Patiently waits for reply from Chriss When I explained to the guy what avatar I wanted, that wasn't what I meant! Originally Posted by iwacelect.

On one hand, I really don't want to spend that much on getting it fixed, as TV's seem to be such a throw away item these days. How do I know that once I fix this, something else isn't going to go wrong?
I live in the Northern suburbs of Melbourne. Which PCB of the above mentioned is the most likely to fail? Any help is greatly appreciated.This morning our four and half year old Panasonic plasma TV died.
After turning its power button on, normal burst of a several green fast blinks of power indicator appeared and two slow red blinks followed. No picture were present, fans off, power indicator off. Instead it seems like some kind of safety test failure. There are two of them as there are two main step down converters in this PSU.
Used capacitors are probably 1uF SMD ceramic, generally available. Their purpose is purely to filter possible harsh voltage. To remove this capacitors just use any available soldering station and heat them up, as they are really small they will probably lift off and stick to your soldering tip. Get your telly back together and well.
Why does it works?
Panasonic Plasma 7 blink failure
I believe that these capacitors degraded in time and temperature as well as used ICs and together caused this trouble. As inside TEATs are no power transistors they should be fine. What happened to these capacitors? After I will measure them back in lab I will update this post. Blog Bronislav Robenek. Bronislav Robenek Ask me anything.

I removed these caps and voila TV repaired! Finally picture of the A30C5 without blocking caps: Why does it works?A couple of months ago, Panasonic notified authorized service centers of a warranty extension on SC board replacement for Panasonic Plasmas that have a 7 blink failure. I have spent several hours now searching the internet for notice of the recall and have come up with nothing, including on Panasonic 's site. I must tell you, I am more than a little shocked.
I have found many complaints, many threats to start a class action lawsuit, but no one that claims to know about the warranty extension. Panasonic made the lofty claim that their plasma televisions would last for 40, to 60, hours of life. Owner's of the models have found that 2, to 5, hours would have been more realistic.
Panasonic TC-P50ST50 Troubleshooting Manual
A common cause of "death" is the 7 blink failure. Most commonly, the SC board is the culprit. Panasonic has received enough complaints that they have decided to issue a voluntary warranty extension to replace the SC board.
However, they have chosen not to publicize it.
Panasonic TC-P50ST50 Troubleshooting Manual
So your Panasonic Plasma has no picture or sound and the standby light is blinking 7 times, what next? Let them know what the problem with your tv is and that your are aware of the SC board warranty extension. They will issue you a customer case number and refer you to an authorized service center. When you speak to the service center give them your case number and tell them you would like them to arrive with the SC board.
Now, here comes the part that will make most of you unhappy. If it turns out that the SC board was not the problem, you are then responsible for paying the servicer their trip charge and diagnostic time. If the SC board resolves it, you are home free and the servicer should not charge you anything. Sign in or sign up and post using a HubPages Network account.Pyspark bar chart

Akida's method does not work, we are here because we have a bit of trouble, but Akida and a few are joking here.
In that case, the TV ignored the remote control. Maybe Akida knows how to do a miracle!Panasonic TCPU54 8 blinks picture flashes then dead. When I plug it in, I can hear the click of a relay.
When the power button is pressed, the screen comes on for a second, then shuts down and then the LED blinks 8 times. I unplugged the SS board and then there is a solid light, no blinks but no picture at all. So I replaced the SS board and there is still the same problem. I am leaning toward the SC board being the problem.
When I unplug everything from it, there is still 8 blinks when the TV is turned on. Does anyone have any thoughts? JPG 1. I believe this is just a Panasonic? Heh, the newer ones don't seem to last Questions via PM will not be answered. Post on the forums instead! Thanks for the reply. The service manual you posted is for a TV that has some different boards. This TV has only one SS board. I do appreciate it though. The documentation should be broadly useful, though 8 blink diagnosis in particular -- I'll try and track down some other documents for you.
The manual has a great flow chart for the 8 blink problem, but when I follow it with this TV, it has me check the 1 and 2 pins on the SS52 through SS57 connectors on the SS board.
When I do this, I have continuity where I should. On that flow chart, it leads me to replace the SS2 board. There is not a Ss2 board on this set. Where does it say replace SS2? I only see replace SS? On UT50 guide. ST50 has SS2. Last edited by tom66; at AM. This is on the second page of the 8 blink flow chart. After reading that, I am kind of thinking it might be the A board? Check the voltage there as it shuts down. If it doesn't A is guaranteed to be faulty.
I don't have anything to get in there to get a good reading. The points on my meter don't seem to get a good contact on that pin.
Is there something you would like me to check on there. Sorry for not seeing it. Yes, that has the same function as pin 5.Quick Links. See also: Owner's Manual. Table of Contents.

I'm still nervous everytime I turn it on. I will continue to update. Have unplugged it from the wall and hope by morning it will work as tomorrow is Saturday and my husband spends it watching college football.
In our case the TV worked all day. My husband turned it off when he went to bed and when I tried turning it on the darned red light was blinking. Crossing my fingers - we are still under warranty if this doesn't work. I have contacted Panasonic and I'm waiting for a reply. I'll post the outcome. After less than 10 hours of use on my new 50" there is a huge black vertical bar through my screen.
I see now these are a problem. Wish I had read this before I bought it last week. Waiting to see if Panasonic will replace the defective tv. Followup to October 2 blog entry. It seems that Panasonic has a really stupid policy of ignoring the "blinking light". I called, got the nice lady on the telephone, made an appointment and finally were able to have the tech come out today Thursday. Dumb me, I thought since I had told the nice lady that the light was blinking twice to indicate a dead SOS D Board whatever that is the tech would have such an animal ready to install to fix the set.
Seems even though the TV set has the intelligence to say what's wrong with it the folks at Panasonic ignore that and send the tech to "diagnose" the problem anyway. The tech spent nearly an hour poking and prodding and came up with the same diagnosis the TV set already provided The tech said he would have to order the part.
If that does not fix the problem we will be asking for a replacement.PANASONIC TH-L 32B6D Easy to repair,10 second automatic standby such as No Screen.
We had bought the Panasonic partly out of brand loyalty but that is being severely tested. Lately I've had to pull the plug and wait overnight to get it back on.
Did the email thing to Panasonic and although the say they'll email back within 2 to 3 days I've yet to hear from them.Show 40 post s from this thread on one page. Blinking 8 times. Looked into the SS bored and found shorted Q DG mosfet. I have yet to find any other short circuits on any components. I wonder if I just replace this DG Does anybody know a good substitute. I don't feel like spending 50 bucks on eBay for a repair kit for this board. I have another Panasonic sustain board that uses a few different mosfets.Best hunting pants for stalking
The heat sync handling the dissipation of this high speed switching mosfet and diode is less than adequate for the task at hand. The bottom of the ss board is dark in the area.
Bad design in my opinion. SO do you have the specs for the DG?Ag maritime fleet list
With D, what are the markings on it? Personally I doubt it. They've had more than sufficient time to sort it out, if it did cause it, that's poor design. I'm going to hug my PZ80, because it looks like there are no good plasmas made beyond about Oh btw.
There are arc marks on every screw lug of the ss board.
A shame that panasonic went this route. I however have a tc-p55ut50 with a busted screen. Looks like its part scavenging time. Did you see the arc marks on the panel?
I think Norcal highlighted a quality issue with this series where the screws were loose. Do you think poor earthing may have killed this? Is the 55 SS the same board as the 50? If you only have 1 part to fix this nothing else in the stash.
