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.
That situation clearly indicates that no signal is coming to the set in its present setting. Have you checked to make sure that the tv's input is set on the right input setting. Mine always defaults to "Antenna" which drives me nuts cause I get that big blue screen with "no signal". It seems to do that at the slightest provocation, too. After 5 years, I still have to think twice before checking it. If that is not it, make sure that the cables are plugged in. If that doesn't fix it try another type of input such as HDMI or S video, composite, etc - one that you are not using. Don't forget to switch the input to it. Good luck!
If you have the same problem with both monitors, it sounds like a display card setting or problem. The chances of you having the same problem with different units is 1- 50. Try the monitors on a different PC and get back to me.
A " no signal" message on the screen means that the set is telling you that it is not receiving a signal from whatever component you have hooked up to it in most cases. But the main be can be bad. The input connections are on the Main bd. Try hooking up another source(Component) to that input and see if you get a picture. If you do then yo either have a bad comoonent or bad cables. If you do not get a picture then your Main bd is probably the issue.
How do you have your DVD player hooked up to your TV(i.e. composite, s-video, component)? Some DVD payers and TVs have menus to switch inputs and if you somehow switched off the input your players are connected to, you'll get a "no signal" message.
First try hitting the input button on your TV or the Input/connection option in your TV's menu.
If that doesn't work try hooking up the DVD player(s) with the composite Cable(yellow), the component(red,green,blue) and S-Video(black/round) at the same time. If you scroll through your TV's inputs you should get a picture on one of these connections and the TV should display which one. The display will usually be in the corner of the screen.
Try the following:
Right after power on, tap the F8 key to see if you can get a short menu to come up.
If it does, select "Safe Mode."
If your screen looks different, it may be just the driver for the display card or monitor is trashed (Windows like doing that, keeps us challenged).
- Open Control Panel, then System, then Hardware, finally Device Manager.
- Locate Display adaptors, open and delete the adaptor listed (all, if more than one.)
- Locate Monitors, open, delete any listing there.
Windows should 'find' two 'new' devices and install the drivers for them.
The display may still be different if you had other than the default settings.
Go then to the Display folder of the Control Panel, click on 'Settings' and experiment.
Depending on your Windows version, if you choose something dumb so it makes the screen unreadable, ignore it and Win will ask if you want to keep it and give you some time to acknowledge that you like it.
When you don't, it will just go back to the pre-tinkering settings.
My HDMI has stopped working. I have had a technician from Dish network out to my house 3 times and they have replaced the receiver and the HDMI cable and were unable to get the set to work all I get is a blue screen and a message which reads no signal. I also cannot use mt set using 3 rca cables connected to the component input when set to 1080 I keep intermittenly get a black screen then a blue screeen and sometimes a no signal message. I have to watch the tv set to 720 on component 2 and it is the most stable in that setting. Please send help
