TV Input Problems Troubleshooting for TV Repair of HDMI & Other TV Inputs That Are Broken


This video is designed to help you better
understand the symptoms that your TV is showing and to also help you when gathering information
and troubleshooting when seeking help for your TV repair.
When troubleshooting, be sure to ask the following questions and take notes as you are observing
the symptoms. You having this information will allow us to better diagnose your TV in a quicker and
more accurate way. We will now go over some common symptoms that TVs can show and what
we should look for in greater detail with these symptoms. Here are some questions to
ask to help with the symptoms for troubleshooting if you are having problems with the inputs
on your TV. Have you updated to the latest firmware for
your TV model? Do you get NO SIGNAL on the screen with certain
inputs? Or do you get NO SIGNAL on the screen with
all inputs? If just one certain input is not working,
have you tried a different source and a different cable? For example if your HDMI 1 input is
not working, have you tried whatever source you are using, maybe a blu-ray player, have
you tried that source in a different input, just to be sure that source is actually working
and not the cause of your problem. You could also try a different cable as well
with that source. Do you get video but no sound, or sound but no video? If using component,
do you get a weird color or tint on the screen? Do you have intermittent or no channels over
the air? Are you using an antenna? Have you always received a poor picture on
your screen or is this something new? Have you tried a different TV with the same
coax connection, if that is where your problem is? We strive to

  2. i have sound but no picture on my vizio M550 NV LED. I have it open but would like to know what to do. Thanks

  3. Hi, my Sony Bravia tv (kdl-46xbr45) has been displaying green and purple vertical lines on the screen. The TV operates normally for about 5 minutes and then this occurs.

    It then is constant while the TV remains on. However the Lines disappear once the menu is opened. I think that the lines only appear over an input (hdmi, atv, dtv, etc). I have the TV open and have inspected capacitors as an issue and I think that I can 'generally' rule that out. I am thinking that the Panel is okay as well as the backlight controller. I am doubtful that the T-Con is at fault and am wondering whether I should replace the Mainboard or the power supply.

    I assume that the issue is heat related based on the fact that the issue only occurs after 5 minutes of operation.

    Here are some general images

    Thanks, for all your very helpful videos!!!!

  4. Hello, I got a very particular problem with my TV, I got a LG 32LK310. Some weeks ago I connected my desktop PC to my TV via HDMI, I connected in one of the HDMI input and the resolution wasnt ok, then I try the other HDMI input and work OK. Then I try to connect my laptop and in the screen said NO SIGNAL, the I try with my PS3 and said the same thing. But, when I connected again my desktop PC it worked OK. I try with many laptops and didnt worked, only worked with my desktop PC in both inputs.
    The others input (AV , VGA, USB) work ok. 
    Is there a solution for this?

  17. hello, I have a Quasar SQ1901 19" LED tv. the hdmi ports & component port stopped working out of nowhere, but the TV Input works just fine. it occurred when there was a rain storm. I called the company & they suggested I send the product to them for an exchange, but it'll take an additional 4 weeks til I could get another one. Iniially, it wouldn't come on at all. Only the standby light would switch to blue & stay with no display. after that happened, I kept the tv on standby for an hour & then it started to work again, however, now the hdmi input & component input is showing "No Signal" & I can't play my PS4 without the hdmi ports. I used my ps4 on a different tv in the house & it worked just fine. the problem is just the hdmi & component inputs on my tv now. help?

  20. I moved a flat screen from my cable box with HDMI to another room with just a cable connection. It says ANT next to the only cable connection but I have no selection for ANT in my input selections.

The Tv is an older model Westinghouse

  22. Hi There I have a Sharpe TV Model # LC-42SB45U purchased Feb 09. Lately the Input drop down box appears without a command. This happens intermittently. It can drop down and highlight the location it's on and fade away after some 10s of seconds or it will just rotate through the inputs and settle on one at some point even though there may be no input on that portal. I've tried cleaning the ports and cables but that doesn't help. I've also tried disconnecting all external inputs and just left it on the coax tv cable but the problem persists.Any ideas?Bill H

  39. I have a Westinghouse tv. it's been working fine for some years. This morning when I turned it on it started going through the input modes and won't stop. tried unplugging. Tried customer care, no nothing. When you hold the button on the side of the tv it will stop but you still can't see anything. Soon as you let it go it keeps going. When I tried pushing input on the remote it kept going but it was a little longer pause between switching. So I tried to turn it on again and it showed 3-0. Hit input and it's still doing this. Can you help me please? Thank you in advance for any response you give me.

  47. My insignia tv HDMI1/DVI is now gives no signal whenever I plug anything into it. However If I plug My fire stick into it it shows the amazon logo for a few seconds then goes back to black. This all happened after a lightning strike.

  48. I have an old Toshiba tv 2007 model 26HL47. I have direct tv. It was working fine. then the tv decided to change inputs, not sure why. When I hit the input button on the remote the only input options it allows me to use are dvr, compact disc, vcr, or cable. The direct tv is inputed in the hdmi 1 location. But on the input screen it has all the hdmi inputs in light gray and the word hidden after each. I am unable to switch back to hdmi 1.
    is there a solution?

  49. I have an imperial led tv it was working and all of a sudden when I touch the remote to antenna to fix it its showing no channels I auto scan and still not picking up any channels. But everything on the tv remote is working. I even watch DVD shows on the tv but the tv channels not picking up

  50. I can’t change my Insignia TV’s source from tv to HDMI. I can’t use the TV’s panel of buttons or a remote control. If you hit source/input it shows the TV at the top of the list & it’s highlighted. Nothing let’s you scroll down to : comp/av – HDMI1-HDMI2-VGA or USB.

  51. My Sharp TV will not let me use Antenna and get a picture but it is ok if I hook up cable. Is my TV dead.
    I put on antenna, hook it up to air and nothing.
