When tv is turned on, screen shows white w/ blue logo, then shows "VGA" and "no signal" on a blue screen. After a minute it turns off. We cannot get a picture. We have a Time Warner cable box hooked up.

Hi,

Please remove the batteries from your tv remote and then turn on the tv directly from the tv itself. If it stays on that means that your remote had an iffy power button that was the source of the tv constantly being turned off and on. Thank you.

Select the input channel for your Fire TV - Turn on your TV and select the input channel for the HDMI port you used to connect your Fire TV. You should then see a loading screen with the Amazon Fire TV logo 4.

Purple Panasonic PC>TV Problem:
The VGA cable uses three primary color RGB channels.
Red, Green, and Blue.
The picture is made up of pixels or dots arranged in a grid along the "X" horizontal axis and "Y" vertical axis.
The computer mixes the intensity of each color channel to create a unique color per pixel.
All RGB at 100% creates white.
R+G creates yellow.
R+B creates magenta, ie purplish.
G+B creates cyan.
So a purplish tint sounds as if your Green wire has no signal, which may indicate a faulty VGA cable or VGA socket.
Put another way, (R+G+B)-G=R+B=magenta.
So try another VGA cable, spray all socket pins with "Servisol " or similar contact cleaner.
0%<--------->100%

Magenta<--->Green
Yellow<------>Blue
All 0%=Black; All 50%=Grey; All 100%=White.

Hello, I have pulled out hair over similar problems. You either have an internal problem inside of the TV or you are losing your source for the picture.

These sets usually have a a Menu which tells the TV to go to a certain input socket for its feeding signal. If you have a bad cable or USB plug, the TV loses its feed and displays the Base Dell Logo.

This feed can be a HDMI multiple wire, or if you have a tapeplayer, CD deck, or Computer feed, they may be toggled separately. On some of my older equipment, I need to switch the TV ports through my Remote to get the appropriate appliance to show on my TV screen.

Depending on your Warranty, you may want to call Service. Sometimes dust can cross circuit the electronics and cause the problem you have. The cable feed wire can also be shorting and causing a loss of signal. Check you cable connections.

Sounds like the video card could be bad. Also make sure the connections from your cable box are securely tightened.

VGA no signal means "no signal" from the computer on the VGA (blue plug) cable... ...if the computer works check the cord for loose connection or get a new cord...if the computer is hooked to the digital cable (DVI/white plug)...set the signal source on the monitor to digital...

Don't forget that the TV source or input needs to be set to "PC". Once that is done turn the netbook OFF, then plug the VGA cable into the netbook and start the computer. The computer screen should automatically show up on the TV.

Hi,

Hold down Fn and tap F5, you may have to tap F5 a couple of times to get it to switch screens.


Regards.

Sounds like your resolution on your computer is set too high for your tv to accept. Try putting your computer resolution down to 1024x768 or lower and see if that works.
