If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

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

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

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 , starting the flashing light.

If you are in situation one, then the TV 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.

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.

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

this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.

for your VP50, it could just be simple as a power supply but it could also means more. Do you have the amber LED light when off and green when on? if so, try the main board first. If that doesn't resolve the problem, then change the sustainer boards.

SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

Good day sir Thor!!!!


I already encounter that kind of problem many times..It looks like all normal even the green power light is not blinks or change to red or amber color but still no sounds or picture on TV..

Sometimes it will happen to plasma TV in all brands and model..It cause of faulty main board..

This is the sample picture of main board of your unit..Part # (3850-0142-0150)

Just replace the board to fix your TV and it works again..

Note: When you install the board make it sure that the static energy on your body discharge to ground to avoid corrupt of main board IC..

EXAMPLE: open the cover then find the main board..before you do that make it sure you hold the metal portion of your TV to discharge static after that you can now freely replace the board and also make it sure to memorized the connector to avoid damage to make it sure take a picture on it before unplug connector for future reference in case..

again discharge static please!!!..Only few tech or other people know this that's why when they install new boards its not works even it is new..I discover this base on my experience and study..

Hope it helps..

Please don't forget to rate!!!!

Thank you using fixya..

It might be,

Audio is usually on a separate power source from the rest of the TV and what I'd do if I were you would be checking the power output on the power board for the amplifier.

It may be something as simple as a blown fuse (and nothing else!) or, more likely, bad capacitor or (again more likely since you said it happened soon after you bought it) blown fuse because of a shorted component somewhere in the amplifier.

I would suggest to remove the back cover and visually inspect the capacitors on the power supply with value of 3300uF/10v for bulging/leaking conditions on the top.

Plasma does stay powered on


Your sustainer board is probably bad. You need to get the Y & Z sustainer boards replace then it should be okay.
