Question about V, Inc. Vizio P50HD Plasma Television
I have Vizio P50HDM TV When I return it on I here a clicking sound and I believe the light goes green a few seconds later theres nother clicking sound I believe it comes from another are and the light flashes orange (I believe it goes to safe mode). The TV is about 3 years old and I had a Sears service guy come out he did not seem to know much but said it maybe the Plasma screen or the display board part #6870QZH044B. He did this without even removing the back of the TV. He then informed me the TV Display card was no available and the TV was scrap. But when I went on e-bay I saw the the card. Do you what maybe causing the problem.Puzzled
It really goes to safe mode to prevent further damage..it happens when the systems detects a fault during start up..it's really hard to point out the exact fault without visual inspection and actual test and inspection of parts..it could just be a point size solder or dirt stucked between the pins of an IC or a resistor loose solder..professional service is suggested..

When TV does not start, and sometimes you hear a clicking noise, that means that 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
