    Does anyone know what a service call on this is going to run? Because of course this doesn't break until after the warranty runs out

  • dabraham6 Dec 13, 2008

    I am looking for parts online at the website from my owners manual and I can not find boards that are sc, su, sd. I can find PC Boards c1, c2, c3, etc. I guess I am not sure what I am looking for in order to see what parts may run.

    i was on the same partstore website and without knowing exactly what board or part i'm looking for there are too many parts to go through. i guess calling service on it will be what i need to do. thank you for your help on this. our plasma will not be looked at for a while as it is bad timing. this is a great website to get help on

    no video. audio is fine. red power light blinks 7 times. just stopped working. I have 4 yr warranty through best buy and am still waiting for them to find me a technician,

    After a year of working just fine tonight the tv will not power on but the red standby power light flashes seven times. Panasonic says by phone yes they've heard of the problem and lined up a local repair shop to come out. In a week.

    From the look of all the messages on several websites this has been going on for years.

    Our TV same model 42 Panasonic Plasma just shut off tonight. When we try to power on, the red light flashes 10 times, then stops for a couple seconds and then flashes 10 times again. We tried shutting off power comletely and waited quite awhile. Still the same result. Just passed warantee (of course).



    Anyone have a clue how much this will cost to have fixed?

    What level of reliability can be expected post repair? I am also outside of warranty with 7 red blinks and received a quote for repair, but concern remains whether spending ~$500 will be wasted if a design problem or something else is shorting the SC board which will not be covered by 90day parts/labor warranty.

hello you have what you call a "shut down circut" it is for safety and when one of the internal boards gets shorted or is not working properly, service doc reads as follows

7 Blinks SOS:
Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times


thiera blinking 7 times is cuase by a fualt in sc,su,sd boards

Ihello, I would recomend a online search for a local certified hdtv plasma repair service center , find a service site that provides a free estimate they will come out and check your set free and also let you know what it will cost. they do this becuase theres alot of competition so repair shops will try to get your business. make sure to call and talk to the service center first let them know what the trouble is they should be able to give you a ruff idea of the price over the phone. usually ranging from 250 to 400 for some boards depends what board and the cost of it, also you may want to find the part yourself online and see what the cost is before you pay way to much for a part.when you get your estimate then take the plasma to them it is cheaper if you do this instead of them coming out, google search locally in your area first then if not possible to find some company close by look for a little further away next county or even state, since they are mobile field techs so they will come out to you and check your set.. key word "plasma hdtv repair service" hope this help

I have a panasonic plasma tv. Model #


I don't know but I'm having a similar problem. I have a plasma
TH-50PZ77U. It will run for a while and then shuts off. Also, the volume goes up and up and then it shuts off at times. Like I have a ghost here. I had both of my sat. recievers replaced. It seems to get worse over time with shut down. I called panasonic and they had no info and denied this was an issue but I beg to differ from my research here online. It's only a few years and we paid lots of $$$. They gave me a # for service 1 hour away!
