PANASONIC PLASMA MODEL TYST42PH20 TURN IT ON AND GOES INTO SHUT DOWN


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

Tv worked fine one minute and then when turned back on no picture or sound. Indicator light at eye came on for a second then went off. Whats the problem?


If the led goes off , and TV turns down completely, then the power supply unit is failing. In that case the PSU board must be tested and eventually replaced.

If the led stays on , or is blinking then the TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Cant decide which type of tv is better


LED is a couple years old and so far not many complaints but they won't be around long. Plasma is much more expensive to repair but a great picture. LCD 120hz 1080p is probably the way to go if money is no object. Stay with a brand name such as Samsung, Panasonic, Sharp, stay away from Polaroid, Ilo, Dell, Westinghouse, Olevia, these are brands that have very poor customer support and parts availability. I am in the service industry and I see it everyday. Happy shopping...

I have a Hisense plasma tv and it will not power up. we had a power surge and it usually powers back up but when the power came back on it didnt power up like it usually does. What can I do?It usuall goes...


Try first unplugging the TV for a couple of hours, after a power surge the TV often stays in protect mode.

By unplugging for a while, you drain power completely, sometimes this can fix the problem.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

Clicking sound!


The TV is on protect mode. The clicking sound is the protection switch that keep turning the TV off to prevent further damage, this happens when a fault had been detected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

Red led stays on after turning off.


Aren't you talking about the standby led? cause that is perfectly normal... when it's on it means you can turn the TV on by remote, usualy it goes away when you turn the TV off manualy by pressing the OFF button on the set, but is this really your problem?
