Power light comes on and blinks then tv shuts down.
I am currently having the same issue as another member (Pserrano) with the same model tv. I have copy and pasted his question below.
"My television will not turn on. If I plug it in, or press the power
button the red led lights up 10 times. Every other blink is slightly
longer the the other. Are you familiar with this problem? Thanks you
in advance for your help."

Hello, If you will look the power light blinks in a pattern. depending on the model number it has either a bad "SS" or "SN" board in it, it's the board on the right side looking from the back. This is a common issue with these sets....tks
Thats a common issue for that model which is caused by weak DM capacitors. When the power is down the caps discharge then they cannot recharge when power is restored and the led blinks non stop. Thw WS48511 - WS65511 DM repair kit from www.tvrepairworld.com has the caps and the repair instructions which usually solve that issue.
It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
I hope this will help in solving the problem......
I have a Sony Grand Wega 55 HDTV, Its 6 years old. Problem is as follows: I press the power button and the TV warms up and goes on for about 30 seconds than shuts off to a no power screen , with the power light flashing green. Than after about 60 seconds the TV comes back on for about another 30 sec and shuts off again. The longer i leave the TV on the longer it stays off when it starts blinking the green light. Can anyone tell me if its the sensor or something else? Is the part I need attainable with the ability to replace it myself.
Look forward to your replies.
Hello well this kind of problem all the time is because you have a fan problem and you could have dirt inside of your tv and sounds also like a ballast problem i have this issue also and I got connected on the live chat that a web say has that they call discount-merchant they sell parts and lamps for TV they could help you they help me twice.
hello, panasonic plasmas have a safety shut down circut to protect the main panel when a short is present or internal circut panel is non functional some info i found in the service manual for 10th generation plasma
if your tv is still under warantee take advantage of the pany free service other wise it is a matter of exchanging the defective board then you will need electronic skills for this repair if you plan to do it yourself. it would be wise to have a skilled tech check it out and give you a estimate there are some techs that will come out and check it for free and give you a repair price.
here are some repair manual tips for blinking panasonic .. i didnt find 9 blinks on this manual i may be using a different manual but these are panasonic plasma blinking fault tips for 10th gen
becuase all models have different blinking codes you may need the model specific service manual
for 10th gen model some models 2008,2007,
8 Blinks SOS: Pin 91 of the MPU IC9003 monitors the status of the SS board. During normal operation, pin 8 of connector SS23 outputs a low to pin 91. If the SS board becomes defective, a high is provided to pin 91. As a result, the unit shuts down and the power LED blinks 8 times.
9 blinks panel config sos
10 Blinks SOS: The SUB5V and DT9V sources created on the A board are monitored by IC1100. If they are not present at pin 30 and 34, the MPU shuts down the unit. The power LED blinks 10 times.
10 Blinks SOS: The F_STB_15V of the P board, as well as the derived SUB5V and DT9V sources are monitored on the A board for excessive current. If a short circuit is developed in one of the supplied lines, pin 114 of IC1100 receives a high. The SUB5V and DT9V lines are also monitored for excessive voltage. When an over-voltage condition is detected, a high is also output to pin 114 of IC1100. The DT9V is provided to a DC/DC converter to create the BT30V for the tuner. If the BT30V becomes excessive, a high is output to pin 114 of IC1100. A high at pin 114 of IC1100 causes the unit to shutdown and the power LED to blink 10 times.
The problems you are having are an indication of a Power Supply problem. The issue could be in the switching power supply or the High Voltage Power Supply. The shutdown circuit is activating which is allowing the TV to play until it detects an over-current event. When an over-current event happens the shutdown circuit will turn the TV off. I would suggest that you check the Horizontal Output Transistor, the HV Transformer, the Horizontal damper diode, and the capacitors that are in parallel to the damper diode. The important thing is to find the component that is causing the problem. If you do not have a background in electronics I would suggest that you get a qualifiedelectronics technician to look at the set.
