When you press the menu button, does a display come up. Blue screen means it is not receiving a video signal of any kind. So check the signal from your satalite receiver on another tv if you can. And as Dmr says, try signal from another source such as DVD, etc.

All the best

Do you have a DVD player/receiver or a VCR receiver that you can connect to to test the tv with?

    What type of cables are you using to connect the tv to the satellite receiver? And where are you connecting to on the tv?

Why does my Sony Google TV NSX-46GT1 46 in. HDTV LCD TV powers up, displays application screen on bottom, makes a computer chime and shuts off completely, and starts the same process over and over aga


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

How restore signal on technika 32 lcd 207 tv


Blue is no signal, first see if rear inputs work with a DVD etc connected as this will rule some things out.

If using for example a cable or satellite box, remove it and the set from power for several minutes and then power both back up which would allow them to try to reboot.

Toshiba Satellite P105-S9722 white screen on stat up


Don't assume. Diagnose.

Problem could be graphics chipset, Video Cable, screen Inverter, or LCD screen.

Graphics chipset:

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.
(Back of laptop - Blue)

Example of a VGA Cable, and a VGA connector, (Port on laptop),

http://en.wikipedia.org/wiki/VGA_connector

If you have a CRT type of monitor (Looks like a small TV), you can use it, or a flat LCD screen monitor with a VGA cable.

The Toshiba Satellite P105-S9722 Notebook PC, also has a DVI connector on the back of the laptop. (Next to the blue VGA port)
You can connect a flat LCD screen monitor with a DVI cable.

Example of a DVI Cable, and DVI connector,

http://en.wikipedia.org/wiki/Digital_Visual_Interface

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default the display should be on the external monitor.

If not;
Press, and hold down on the Fn key, (Bottom left), and tap once on the F5 key.
The F5 key is the Display Toggle-Over key.

You will see a list. It 'hot cycles' through the list, until you come to the external monitor device you are using.

External monitor display shows no white screen?
Your graphics chipset is good.
Go on with the diagnoses.

Problem is with the Video Cable, or in the Display Assembly.
(Screen Inverter or LCD screen)

Video Cable:
The Video Cable attaches to the motherboard under the Switch Cover, and about at the F2 and F3 keys.
It then routes under the left Hinge, and up into the Display Assembly.

From there it connects to the screen Inverter, and back of LCD screen,

http://www.irisvista.com/tech/laptops/toshiba-satellite-p105/big/toshiba-satellite-p105-11.jpg


From;

http://www.irisvista.com/tech/laptops/toshiba-satellite-p105/take-apart-1.htm

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-P105-P100/remove-lcd-screen-inverter-1.htm

Due to normal opening, and closing of the laptop, the Video Cable may become pinched, and pulled on.
This can lead to a simple loose connection of the Video Cable TO the motherboard, or TO the back of the LCD screen.

(The screen Inverter connection should also be checked)

Visual inspection will NOT do. You need to physically see if you can plug the motherboard connection, and LCD screen connection in.
It could be just loose enough you won't be able to see it, but will affect the display.

Sheath of Video Cable needs to be visually inspected for signs of damage. Signs of damage to the sheath, may also mean damage to the tiny wires inside the sheath of the Video Cable.
(Stretched/Broken)

Assurance that the Video Cable is not the problem, means checking out, or have checked out, with a multimeter set to OHM's, to run a continuity check of all the wires.
('Mom and Pop' computer store. See if they will check it)

Or simply replace the Video Cable. (After you fire up the laptop, and see if loose connections was, or was not the problem)

http://www.batterysupport.com/toshiba-satellite-p105-s9722-cable-p-377633.html


(Left side connects to LCD screen. Right/Top connector goes to motherboard. Right/Bottom connector goes to screen Inverter)

Video Cable checks out OK?
Go on to screen Inverter.

http://www.ebay.com/itm/TOSHIBA-Satellite-P105-S9722-laptop-lcd-Screen-Inverter-/250759700669


The plastic thin frame in front of the LCD screen, is the Display Bezel.
The screen Inverter is behind the Display Bezel, and mounted at a location towards the bottom of the LCD screen frame.

A screen Inverter is tested with a sensitive multimeter. Read fairly expensive,

http://www.fonerbooks.com/test.htm

It is for this reason that those who do not have access to a sensitive multimeter, usually just replace the screen Inverter.
(Also low cost, and ease of access to replace)

Screen Inverter checks out OK?
Problem is the LCD screen,

[ Bet it's the video cable, or screen Inverter, that is the problem ]

[ Primer:
An LCD screen cannot produce light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, (Or two of them), or a series of LED's.
(Light Emitting Diode)

The Toshiba Satellite P105-S9722 Notebook PC, uses One CCFL for a Backlight.

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height,

General example,

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

A CCFL contains -> Mercury, just like Fluorescent lighting used in homes, and businesses.

A screen Inverter is used to convert the power from the laptop, for the Backlight, and LCD screen.
90 Percent of the Time the fault is a bad screen Inverter.

Primer over.

Tried hooking up my tv to the satellite cable but I have nothing but blue screen and it says no signal. tried to auto scan and it wiped out all my channels. How do I fix this problem?


I think I see what happened here. Normally you have the tv cable connected to one connector and satellite or others to different connectors. When you want to switch you use your remote or the tv controls to change the source.This will preserve the scanned channels as well. On your remote you should see source or something like that. As you select it it should shows options like antenna, cable aux1 aux2 and so on.

So hook your tv up and rescan your channels. Then hook up the satellite to one of the other inputs. Then use the remote to switch the source. You will never see more than one sateliitel channel at a time and you will have to use the satellite remote to change channels on the satellite box.

Turn on goes blue then turns off


The most common reason for a TV to display a blue screen with no picture is because the source device has not been set to the proper mode.

If you are using a cable or satellite set-top box, ensure that it is turned on and set to an active station. If the set-top box is connected to the television using a coaxial cable, then the television should be set to Channel 3 or 4 to receive the signal.

If you have are using a VCR that is turned on, but not playing a tape and not tuned to a receivable channel, then a blue screen will be displayed on the TV. To resolve this, turn off the VCR or tune it to a receivable channel. If a cable or satellite set-top box is connected to the VCR using a coaxial cable, then the VCR should normally be set to Channel 3 or 4 to receive the signal.

If the blue screen is not because of a connected VCR or set-top box, the TV may require service.
