View Sonic LCD TV - N3020W

My TV has a blue screen. The remote control does not communicate with TV. The butonns on the side do not work. I have taken this TV to a small repair shop but they said they could not get parts from View Sonic. They told me it was the power supply. Does any one have this problem ? Is it worth geting fixed? Where would I get a power supply if this is the problem?

SOURCE: ViewSonic TV sound but no picture

If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

Theinverter is the high voltage board that provides variable power to thebacklight lamp. This is the most common. When inverter is faulty youcan get no picture, or a very dim picture that can only be seen bypointing a torch light with a 45 degree angle on the LCD surface fromvery near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
Thisis quite uncommon, but happens. If the TV had been hit or moved the LCDcable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
Thisis the board that controls the video signal, it is difficult to test,as there is need to read determined values on IC pins. To test thisboard you need to purchase a service manual and follow thetroubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where youconnect the video and audio cables, if a signal board is defective,then you may get no picture on particular inputs located on faultyboard.

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.

SOURCE: i have a 20inch view sonic LCD TV and it says menu

When menu is locked this means the child lock function has been activated on the system. This is usually to stop kids from tampering the remote and adjusting settings. The procedure for doing this differs from unit to unit Refer to your user manual to determine the procedure for unlocking the unit.
Hope this solution has been helpful?

How u get it off the **** screen When i hook up my xbox its comes on but its on the left part of the screen & the right side stays blue


Good day!!!

Please try to input other device such as DVD player to determine which device (x-box) or (TV) need to set up full view settings..

If you play DVD and the screen is fine so you need to set up the full view of your x-box using remote..

If you play a DVD but the screen is still half..You need to set the full view of you TV using remote..

I you have more queries and clarification just add a comment..

Hope it helps..

Thanks for using fixya..

I have a soniq 42"


Ah, the old universal remote isn't so universal anymore is it? Most "universal" remote controls were designed for the old tube type television sets. There are some seriously nice universal remotes for new flat screen TV's, but most of them are pretty pricey. The only reasonable flat screen universal remote that I've found (that actually works) is the Vizio HDTV Universal Remote. It's about $25, and believe it or not ... Wal-Mart carries it in the store.

The menu button is locked on my view sonic tv how do i unlock it????


Depends on the model of TV. Some ViewSonics will unlock the menu if you Press the Channel + and Channel - buttons at the same time. You should see a message stating the menu is unlocking. Once it clears you can use your remote control to make any necessary changes to the TV.

Harmony 880 display is backlit but menu won't display. It seems to still work (pressing the button I know to be "Watch TV" turns everything on ok). Is the LCD broken?


Sometimes the LCD screen fails on the 880/890 series. But, there are a few tricks you can try that have brought the LCD back to life.
Some LCD problems have been solved by updating the remote's firmware while the remote has been placed in 'safe mode'. To do this, launch the Logitech Remote software on your computer and click on "Downloads" (on the top menu bar). Then, take the battery out of your remote and at the same time you connect the USB cable to your remote (it should be already connected on the computer end) press and hold down the Off button at the top of the remote. This will put the remote in "safe mode". Continue to hold down the Off button until you see the message "safe mode requested" on the remote's screen and the screen starts blinking. Now, since your screen is not behaving properly, you may or may not see this message, but after about 5 seconds you can release the Off button. Now, go back to your computer and click on "Firmware". If the software is able to communicate with the remote, an update to the remote's firmware should be executed. This has solved many a 'blue screen of death' problem. Good luck!
