SOURCE: Vizio L37hdtv10a fails to fully turn on

You will have to isolate the main board and Inverters.
Unplug the inverters and turn on the set.
If it "turns on" then try re-connecting each inverter seperately to see if only one is causing the problem.

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

Logic Control D Board got nothing to do with this problem. This is your main power supply gone bad(usually not the sub power supply). I just repaired my VIZIO by replacing main power supply. Just remove back cover and your board will be right in the middle of the screen. Just get board part/serial # and google it. My best price was through eBay(around $100). Everything is fine now.

If you lost the control when trying to use the switches on the TV, it means that the Main board is not functioning, this can be due to bad processor, bad unsteady DC. The main board send the ON signals to the Power supply and the backlights inverter board.
You should inspect the power supply module first since unstable DC can cause a lot of problem, if the voltages and components checked out OK , then you may ahve to change the main board. It will require in-depth troubleshooting to really narrow down the cause of the problem.
Please read my guide first to see if you will want to DIY repair or not.

Could be the capacitors going or have gone out. This is a common problem with Vizio TVs...including mine recently. Check out YouTube for tutorials on how to change the capacitors.

My vizio p50 hdtv20a have sound but no picture


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

What is voltage supposed to be for P on pin on power supply?


The power on is usually 3.3vdc, but on some sets it's at 0v to turn on the set, and 5v when the set is off. Your power supply maybe ground activated. If you replaced the main board, then the power supply is your problem

Vizio vw37l hdtv20a standby light on but wont turn on


you either have a faulty power supply or faulty main board. Vizio power supplies on the older sets are pretty decent. It's usually the main boards that go. These older main boards tend to be pricey so it may be better to buy a new set.

Vizio VW37L no power


Check for bad capacitors in power supply, check voltages coming out of the power supply, if voltages are good, bad main board.. Vizio's are notorious for bad main boards.

Do you have back light when turning on the TV? if you do then just replace the main board should resolve the problem. if you do not have back light, you will need to replace the inverter board(s) depending on your model. The inverter board(s) is located on the left side of the TV facing back of TV. you may have two inverter boards depending on your model. the other is located on the right side of the TV. Both mount vertically.
