You MAY have some condensation in a high voltage path inside.
The noise might well be from leaking high voltage.

I recommend you let it climatize for a couple of days before trying it again, otherwise you may damage circuitry not normally involved with production of the HV.

TV turned off by itself today, It initially makes a clicking noise, the green power light flashes and goes out after 2-3s hear 2nd click and nothing happens. No red blink lights, nothing.


These 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.

Hello i have a panasonic TC-P50S1 plasma tv (2009) and it does not turn on properly anymore. You turn it on and then it turns off and start to blink repeatedly.

Loud noise then lose picture


The green power LED probably is merely indicating that power is getting to your TV but the internal power supply is failing as evidenced by the loud "pop".

My Zenith plasma TV blinks green 4 times then goes red, No picture. None of the Capasitors are blown.


I had AWFUL customer service. (Sherry is DREADFUL her # is 1-877-543-8325 she is in"executive services". Ask to speak to her directly...if you would like ZERO help.)

They WILL NOT extend the warranty, even though they know there is a defect with this AND other models. Zenith name on the front...LG guts in the inside.
Ours turns on, screen black and then clicks three times and then turns back off.

Rca HD61LPW42 -- we just replaced the color wheel. now we get a picture but only for a few seconds. then it turns off and after a few seconds restarts. this goes on indefinitely. a couple of times...


Hello

If the power light blinks slowly,

you've tried to turn on the TV during

the lamp cooldown cycle. Wait

approximately 30 seconds, and the TV
will turn on automatically.

If light blinks, pauses for about a

minute, and blinks again: the lamp is

trying to turn on (TV will turn on

when successful). If TV doesn't turn

on and sequence continues, the lamp also
needs to be replaced.

To order lamp call 1-800-338-0376.

Have your TV serial number

and lamp type available (you'll

find this information on the

sticker that's on the right side of
the TV).
OK.

Philips 42PF7320A blinks 3 times every time i hit the power button


The SSB is small self contained board that u connect your Antenna, and HDMI to. An error three is a communication error between the SSB and to Logic board ( located underneath the SSB on the back fo the plasma panel that is just below the power supply. U can check parts.com and see if u want to purchase a SSB for this TV. Is the 3blinking lights coming from the front of the TV. Also check the power supply and see how many times the green led blinks on the upper left of the power supply and let me know.

Loud bang, unit stopped working


I have seen the caps in the power supply vent, which means they get hot and the top pops up and splits open, resulting in the "bang" sound. If you have experience in electronics then remove the back of the set and examine the power supply, looking for any caps whose tops are bowed upward, and replace.
