The tuner or related circuits have a problem,the simple one will be that the grounds in the tuner are loose the other posibility is the tuner itself is doing this,make sure the conector were you screw the cable is tight ,if the conector itself is loose it can give you problems too,if you are familiar with tv service and you can solder electronic parts then is something you can do but if you are not too familiar you should call for assistance from a servicer or just dont use the tuner imput and use your vcr to change the channels.Let Us know if you need more information.

My digital tv is saying no singal whats the problem and how do I fix it? we have a huge antenna on our roof

1 – Is the NO SIGNAL issue happening on just one TV?
If it is just one TV that is showing the NO SIGNAL…
-Be sure your TV is on the correct source or input as your CABLE or SAT BOX.
-Press the TV button on TV remote control to turn your TV ON.
-Press the INPUT button on your TV remote control.
-Cycle through all the inputs on your TV.
-Do this until you are on the INPUT your CABLE or SAT BOX is plugged into.
-You should then see the CABLE or SAT programming show on your TV.
HINT: Your TV will most likely list the TV INPUTS as: HDMI 1, HDMI 2, HDMI 3, VGA, Component 1, Component 2, and so on.
If you still see NO SIGNAL on your TV screen, see the next step below…

2 – If you have your TV on the correct INPUT or SOURCE and you still see NO SIGNAL…
-Remove or unplug the power cable from the Cable TV or SAT set top box.
-Keep it unplugged for 2 to 3 minutes.
-Plug the power cable back into your Cable or SAT set top box.
-Give it some time for the Cable or SAT box to power up, get the signal, and initialize.
If you still see NO SIGNAL on your TV screen, see the next step below…

3 – If you have reset the Cable or SAT box and still have the NO SIGNAL…
-Remove the HDMI cable or other cables from your Cable TV or SAT set top box.
-Keep the cable unplugged for 2 to 3 minutes.
-Plug the HDMI cable or other cables back in.
-Give it some time for the Cable or SAT box to get the signal and initialize.
HINT: Make sure all the cables that are connected to your Cable or SAT box and your TV are tight, undamaged, and secured.

4 – If all of your TVs are affected with the NO SIGNAL screen…
-Be sure to check the ones where the CABLE or SAT come into your home.
-Be sure ALL Ethernet and Coax cables are secure.
-Call your CABLE or SAT provider to see if there is an outage.
-Realign your Dish if you have SATELLITE.

MY tv that goes straight to the screensaver mode like it would on pc. sony bravia kdl32nl140 is the tv.

J, it sounds like it may not be getting any input from cable or satellite, try switching cable and inputs around, try VCR or DVD player. You may need a firmware or software update.
Some forums say to unplug and wait 10 min. then it resets.
Check links below.

Have a 36 inch vizio flat screen it started about four days ago.When i switch from watching a movie on DVd back to regular picture on component 2 no picture is coming up tried chanel 3 an d4 still no...

It sounds like you aren't cycling fully.
It sounds like you are on the TV (RF/Cable) input, then you switch input to Component 1 (for your DVD) and watch the DVD, then hit the input selector again, switching it to Component need to keep switching the input until you are back on the TV / Cable input.

My Sony Projection tv is HD ready, but when I connect the cables from the HD receiver, I have a black screen. Thank you Kevin Davis


With so little information I will have to make alot of assumptions to help you. Are you hooking up a HDMI cable? If so it is straight forward. Plug one end into the HDMI connection on the receiver and the other into a HDMI port on the TV. Note the port designation (HDMI 1 or 2). Enter the menu on the TV and change the input to the proper HDMI input. This should make the unit work.

Thanks for using FixYa and for the great rating.

After warm-up screen flashes and loses color but comes back on and off intermittidly. This is a 50" Zenith Plasma tv. thanks.

Sounds as if a cable connection is bad. Check the cables first. If cable are good, change inputs, if cables are bad replace cables. If it's component, make sure that red, blue or green didn't come loose on both sides...the tv and the source. If you still have problems, check for red video noise on the screen itself, preferably when it's on but with on input (black) If you notice this, your plasma is failing.

Screen starts to flash like a strobe light

It sounds like you may have some bad filter capacitors in the power supply. The "easy" fix could be to replace the power supply board. These capacitors can act up as they warm up.

No signal

you have to take the remote, find the input button, push the input button untill your picture comes back, you should see the input go from cable/antenna, to vid 1--vid2---vid3---if pushing the button a couple of times dont change it, you will have to hit the input button, then arrow down, and select the nexy one, do that untill you find the picture

I just wanted to suggest some things for you to try, if you have not done them already. Try hooking up a known good signal, such as the main input cable from your cable or dish, hook it straight to your tv, and see if you can change channels, and get a picture on low band...2 thru 6, and then if not, how about any picture above channel 6, if you get picture on 2 thru 13 now, it could be whatever you have hooked in between the input cable and the sure you have the tv on the right channel for your receiver, usually 3 or 4, or if you are using another type of video input cable, make sure you have tv on the right input for that cable and that cable is good...check the in and out of your component unit, for correct cable hookup as well as your cables, in reference to using RCA video and audio left and right in and out...a lot of sets and vcr's will go to a blue screen if they lose signal to them....I hope this helps you out some.If you cannot get a picture from hooking your signal straight to your tv, it could be the tuner got a spike from a thunderstorm, or has lost the B Plus source for the tuner circuit. Be sure that it is not selected for an input signal,other than the cable or antenna mode, the onscreen text should verify this, if you can change channels with or without getting video...a picture....Good luck with it.

Cable connection generating static on screen & noise

Hi, it sounds like ya most probably gonna haveta resolder the Cable Connection Socket internally.. they often fracture, OR perhaps it is the Actual Cable Connection Plug itself?.. maybe you need to remake this input connection? Indeed it sounds as if the Earth Shielding is making bad contact...
