WHEN PLUGGING TV IN, RED LIGHT BLINKS 10 TIMES BUT DOESNT COME ON

PLUG IN, IT SOUNDS LIKE IT IS TURNING ON AUTOMATICALLY, BUT THEN THE RED POWER LIGHT BLINKS 10 TIMES, THEN SHORT PAUSE, THEN 10 MORE BLINKS AND SO ON. TV WILL NOT COME ON. WHEN PUSHING POWER BUTTON, IT MAKES CLICKING NOISE BUT STILL DOES NOT COME ON AND JUST BLINKS. TV WAS GIVEN TO ME, I DONT KNOW ITS HISTORY.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

SOURCE: Power light blinking 2 times

2 blinks means the unit is having problem with 12 volt supply.
while power on you can check 12DC on power supply before shutdown.if the voltage is constant before shut down I would recommend to replace D board.

SOURCE: red light blinks 9 times on Panasonic TH-42PZ77U

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.

hope this helps..

if you have a warranty let them check it out before opening the panels, it may void it.... may be an internal power short.

SOURCE: TV clicked and went blank...no picture, no sound.

Most problems with TV not turning ON is a power supply related problem. The relay click are a normal process that powers up the circuit boards. Right now the TV is most likely in " Protection Mode ". The TV detected a bad circuit board and it will prevent the TV from fully turning ON. This keeps the other circuit board from being damaged. The power light blinking is a code.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet. This will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, blinking light codes, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

I can give you some advice on the first thing you need to try. Unplug the tv for 10 minutes. Plug the tv back into the wall or power strip. Try powering on the tv. This may work or may not. It is important to try this before moving on to more complicated troubleshooting.

Sounds like you lamp ballast has gone bad. I good way to verify this is, when you press power on the projector look inside the lens. If you see a small amount of light, then the ballast is good, and the lamp is bad. If there is no light then chances are the ballast is bad.
