Before replacing any more parts you should do some testing: first make sure that the power cord is ok (no, it's not stupid, you wouldn't belive how many times i stumbled on that); next you should check the noise filter; next the power button (including the starter contact); next the rectifier of the power board; next the output of the power board. From there , if you find a faulty output, you should check the parts/boards powered by that output. Only after you have identified the failed parts you should order them.

Hi

hugjean5,

Thanks in advance for choosing Fixya for Assistance


• It could be causes from a bad or group of defective

components


First you need to understand that there are Voltages applied to the

Electronics Components/ Circuits to work.


And these voltages can affect and control the system status, as it has

protections circuits even from the Microprocessor built-in inside your TV.


To know the cause , you may need to open it up ,

Only if you feel you can.

• You may need to measure voltages, But sense of hearing and a

good visual may partially aid you in localizing the problem.



How to test for Continuity



How to use a multimeter


Here are some of troubleshooting Guide:


• When the Plasma TV is plugged in, there’re a few

indications of normal operation. Knowing this will help us

understand what’s going on with the unit when an

abnormality occurs.



1.There is a click from the relays RL402 and RL403

when they are activated.

2.The LED in the Optical Jack inside the DT board turns on

for approx. 4 seconds.

3.Immediately after that, one of the Tuner LEDs (Right) turns on

( Solid Red ) for approximately 20 seconds.


4.The LED in the Optical Jack inside the DT board turns on again for

approx. 1 second and both LEDs (tuner and optical jack) turn off.


5. Then you will hear another click from the relays RL402

and RL403 indicating that they are no-longer engaged and

the Optical Jack LED turn off.)



• You need to check For Standby Voltages

STB 5V and 12V

FSTB 14

My Panasonic TV turns on and off continuously once powered on. It makes no sounds, clicks, or blinks of indicator light. Stays off for 1-2 seconds at a time. All fans are working. any ideas?


Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

One simple solution may be to replace the power cable or the power strip that the TV is plugged in to. If you cannot get any power to the TV even after this step, it is most likely a motherboard or some sort of circuitry issue. Make sure you are using the physical buttons on the TV when trying to turn the TV on; leave the remote out of the equation. If it still does not come on, your TV may be far gone. HDTVs have a lifespan these days of anywhere between 3-5 years for plasma, 5-7 years for LCD, and the new LED tvs are supposed to last anywhere between 7-10 years.
