I unplugged the tv, held the power on button for 10 secs and still nothing after i plugged it back into the power supply.
SOURCE: acer laptop wont turn on has power button light up
This is a common problem with Acer units, both desktop and laptop. The motherboard fails to read the system BIOS at startup. Removing the battery from a laptop merely removes the power source, but not the stored memory. If you are able to locate the CMOS battery, or the cell battery the size of a US quarter dollar, that is the system battery. Remove that, wipe with a lint free cloth (coffee filter) then replace.
If that effort fails upon replacing the cleaned CMOS battery and laptop eneregy source, then a new coin cell may be the solution.
If a new coin cell fails to resolve the problem, the motherboard itself is the culprit. Time for a new laptop or desktop.
Hope this helps you...
SOURCE: only vizio light on
why should i tell you (fixYa) how i fixed the problem for free? You wanted to charge me for your info so i think it's only fair that i charge you for mines. I did figure out and solved the problem.
SOURCE: only vizio light come on then nothing. have to unplug to turn off
there a problem on power side.. chage the ic and the resistor going to ic and check also the signal diode.

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.

It is most deffinately a convergence chip issue. The die for no reason. They can be bought online for around $10 dollars and anyone with experience with soldering can replace them pretty easily. I have done it.
