Tv not working

try changing to a different input source

My Vizio Has a Blue Screen But Doesn't Shut Off Troubleshooting your Vizio TV requires that you first identify the source of the problem. A blue screen on your Vizio TV can indicate that you are experiencing a problem with the video input on your TV, while the failure to turn off may indicate that there is a problem with overcharged internal memory or your power capacitors in your TV.

Finding the cause of your Vizio's problems can involve trial and error.

Check Your Connections The connections leading to and from your Vizio TV may be responsible for your Vizio TV having a blue screen and failing to power down. Tighten the coaxial connections to your TV and firmly press in any HDMI, component or composite video cables connecting to your TV, then check the signal on your TV to see if the blue screen problem resolves itself.

Discharge Your TV's Memory Overcharged internal memory can lock up your Vizio TV and prevent it from changing channels or turning off. To discharge your TV, unplug your TV and press and hold the "Power" button for 30 seconds. Plug the TV back into the electrical outlet after 30 seconds and check to see if the problem persists.
Change Input
The input source connected to your TV may be malfunctioning and preventing your Vizio TV from powering off. The "Input" button on your remote will allow you to select a new input source. Cycle through input sources until you find one that displays an image on your screen and power the TV off. If this method works, you may need to replace the input source preventing your TV from turning on.

Power-Cycle Your Equipment Power-cycling your equipment can solve errors created by devices or with your TV's power supply. To power-cycle your equipment, unplug your TV from the electrical outlet along with any devices connected to your TV. Plug your TV back in and turn it on. Plug in each device, one at a time, and notice if your TV displays a blue screen or has trouble turning off. Repeat this process for each device connected to your TV and replace any devices causing problems with your TV.

This definitely means that you have no signal input to the TV. Check the signal input and switch to the source input that you provide, like cable or antenna.

Refer to the manual (free download here). Generally, a blue screen indicates a very low or non-existent signal. This can happen when the antenna is unable to gather enough of a signal from a particular broadcaster, or if an A/V input is selected, but the A/V device is not on or providing a signal. Since you are not seeing channel information when tuning, I suspect that the television is set to display an A/V input instead of the internal tuner.

With a working remote, locate the TV/AV button on the lower left (manual page 3 - item 8). When this button is pressed, you can choose to display signals on the ANT, VIDEO1, VIDEO2 or COMPONENT jacks. The ANT selection chooses the input on the RF jack such as an antenna or cable TV (with or without converter box). If using a cable box, the TV tuner should be set to Ch3 or Ch4 as determined by your cable box. Otherwise, select the VIDEO1, VIDEO2 or COMPONENT input that has the source signals you wish to watch from a cable box, DVD player, etc. that is connected to the rear input jacks. Page 7 of the manual details the connection and remote operation.

I hope this helps!

Sorters -

Re-connect to me on the chat and we'll get this sorted. I'm really sorry - I got disconnected and the system would not allow me to reconnect to you. I have some ideas but chat would be easiest. If you don't want to chat, post a message here and I'll message back with some things to try.

BElectric.

OK A Blue screen, indicate that there is, or the TV "Thinks" there is NO SIGNAL. Please Check your Antenna Connection. Unplug the TV, for 5 mins or so. You MUST prove either the TV or it's "Signal Source" the Antenna. Try the antenna on another TV, if possible, try another antenna,on the TV, Try feeding in a signal via the EXTERNAL inputs. IF ALL Inputs are proved OK, and the TV, still will NOT display any signal, then it would appear that you may have a "Tuner" fault, or some other underlying condition, that affects the reception. In my professional opinion, in that case is to get the unit looked at by a Toshiba, recommended service center, VERY IMPORTANT to do that. Ask for a "Quote" from that service center, and go from there.

i just have a blue screen and it said no signal on the tv

Hello,

 

Picture quality problems (such as lines, fuzzy image, or wrong colors)

1. Check the cables and connections: Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
2. Check the  display issue with  a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
3. Make sure that the image quality issue is not coming from your source signal. For example: if the image quality issues occur while viewing TV , switch the source to a DVD player to see if the image quality problems go away. If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and . If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem. NOTE: Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
4. Try to Reset the TV ( LCD) quality options. Please look in to User Guide to make the TV to factory Defaults..
5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV . If the image quality problems still exists across all types of signal sources, the TV should be serviced.

I hope that this should resolve the issue. However, if the issue still persists then please contact LCD manufacturer for further more on the issue.

 

Bye.

Mine (2005 vintage) is doing the same thing. Wiggling the connector at the rear of the set cures the issue. however, it must be a loose connection inside. How about soldering the connector?

Any other ideas on how best to handle the soldering of the connector inside the set?
