If the sleep timer is not set, it sounds like the power supply board. As the unit heats up a component is failing or a crack circuit trace is opening up. Someone knowledgeable about electronics can isolate it by causing the problem and using a circuit cooler spray on the board.

When I turn on my 42" vizio all I get is the vizio screen no sound and the remote will not work to turn it off.after being unplugged for awhile (days) i tried it again and it worked fine until i shut


You will need to get a diagnosis done on the set. It could be a power supply issue or a main board issue. Your problem is between one of those two boards.

Vizio 42 hdtv mo picture,no sound


Hi

Thanks for using FixYa. Please check the following—

1. Is Power board output +5V?
2. Is J1 (#19 in the right diagram)connector good?
3. Is DC-DC OK, check the voltage at J1 using a multimeter.
4. Is U4 (3.3V) working ok, U4 is an IC, you’ll need an IC tester or an oscilloscope to check this IC.

After checking this if it still doesn’t work then check P3 D-sub Input (on the D-board). See this schematic for details--

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Vizio 42" lcd powers up with sound only - no picture


It sounds to me that the unit has a faulty inverter board which could be due to an overheated/bulged capacitor. I would send in a claim on it to the factory if it is still under warranty.

I turn on the tv and it has a blue screen and no


Just try to reset so picture will back to normal again, some LCD 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.
1. Unplug the LCD TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the LCD TV power button for five seconds.
4. Plug the LCD TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the LCD TV is responding again.
6. Turn off the LCD TV and reconnect the devices.
7. Turn on the LCD TV.

Hope it may help you;

Regards;

Vizio vx42l hdtv back light


If backlight went out then sound should still work. Are there any indicator lights to show power is coming on anymore? Try unplugging for 30 seconds, hit power button a few times, then plug back in and try to turn on. This drains any capacitors of power to attempt to reset (basically clearing the TV's throat).

Can also try something on a different input. If current input is composite, S-video, or component, try using DVI or HDMI connection as this uses a different board in the TV. If that fixes it, then at least you can try to replace one board instead of entire tv. :)

The main board of your TV is bad. I have seen a lot of TVs have the same problem.
