I have a 42 inch Gallevia model GV 42L. When TV is initially turned on blue screen comes up for about 2 seconds, it then goes black and a screeching noise comes through both speakers on the TV. No Picture and no other sound. Any thoughts on what might be causing this? Thanks in advance.

Sounds like the back light is going out or a connection to the back light has loosened of the years

Yes, a cap will rarely cause this issue.

If blue screen set is ok power wise.

If blue when connections are made to rear inputs also it means it is not the tuner in the set---a good idea is to hook a DVD up, turn it on and then the set--select that input with the DVD already on--

That aside you may want to make the effort to call Vizio and see if this is a known issue or if a software upgrade is available for this issue.

If I had to "guess" it will be the main board that processes all signal inside the set.

Do some research with GOOGLE by model number "known problems" blue screen only etc.

Hi there,
Have you got anything connected to the TV? If so, make sure they are powered on, and all connected correctly.
Hope this helps

any display in the corners of channel number av etc ?? if you turn the volume up and down does that show on the display if not likely to be a dead panel

I have a 42 inch baird tv it will show the blue screen for a couple of seconds and then there's nothing just a black screen

what is the solution?

42 inch hdmi digistar tv has no picture

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;

Don't buy it. VIZIO is not standing by their products.

My GV42L had issues from the ssart and now it shows No Signal and shuts of in 2-3 seconds. I read many similar issues on this site with VIZIO.
