I've never been able to get a signal through any of the HDMI ports on the above TV. Any suggestions?

Hvis TV-en din ikke tar imot signaler til HDMI-inngangen, kan det v?re flere ?rsaker til problemet. Her er noen feils?kingstrinn du kan pr?ve:

1. Kontroller kabeltilkoblingen: S?rg for at HDMI-kabelen er ordentlig tilkoblet b?de TV-en og enheten du pr?ver ? koble til. Pr?v ? koble kabelen til en annen HDMI-port p? TV-en din for ? se om det gj?r en forskjell.
2. Pr?v en annen enhet: Hvis kabelen er tilkoblet riktig, kan problemet v?re med enheten du pr?ver ? koble til. Pr?v ? koble til en annen enhet, for eksempel en spillkonsoll eller en Blu-ray-spiller, og se om du f?r signal.
3. Oppdater TV-programvaren: S?rg for at TV-programvaren er oppdatert til den nyeste versjonen. Du kan sjekke dette i TV-innstillingene. Hvis programvaren ikke er oppdatert, kan det p?virke TV-ens evne til ? gjenkjenne HDMI-signalene.
4. Tilbakestill TV-innstillingene: Pr?v ? tilbakestille TV-en til fabrikkinnstillingene. Dette kan hjelpe hvis det er en programvarefeil som forhindrer TV-en i ? gjenkjenne HDMI-signalene.

Hvis ingen av disse trinnene l?ser problemet, kan det hende du m? kontakte en kvalifisert tekniker for videre feils?king og reparasjon.

As the HDMI input of TVs are only meant to accept video signals (to set HDMI specifications), any SMART TV dongle that attaches to the HDMI port is going to output a video signal compatible with the set HDMI specification. A modern TV like yours will be able to accept the digital video signal from any dongle, as it accepts all the common modern formats (1080p, 1080i, 720p, 576p, 576i, 480p, 480i)

I presume you've checked that the HDMI cables are good, and that the signal sources (e.g., blu-ray player, Roku, etc.) are working correctly. If the HDMI ports are individually selected by four buttons on your Sony remote, which is unlikely, it's possibly a problem in that remote. It's also possible that ports 2 and 3 are physically damaged by abuse. If you have ruled out all of those potential causes, this is almost certainly a problem in the way the defective ports are attached to the underlying printed circuit board inside the TV, or a flaw in that PCB. Too bad it's out of warranty. Repairing this will be a hassle if it can be done at all, and probably not cost effective. Instead, I suggest three possible workarounds for your consideration.

First, if you can find another way to get the signals into your TV, such as using the component inputs instead of HDMI, that will your cheapest and easiest alternative. This will only be doable if the signal source offers other types of outputs besides HDMI. Note that I am NOT suggesting adding any type of signal converter, just a different way of connecting the signal source to the TV.

A second alternative is to buy a multi-port HDMI switch with a remote control which you can find for less than $30 at online retailers like ebay. Plug that switch into one of your two good HDMI ports, and connect your unserved signal sources to the switch. It will be slightly less convenient to use the multi-port switch because you will need to operate one more remote control than you do now.

The third possible workaround is to buy an autosensing HDMI switch instead of the multi-port type, which would eliminate the need for the extra remote. However, an autosensing switch must have only one signal source active at any given time. This may not be possible if one of your signal sources is a streaming device that is continuously powered up. Good luck!

Step 1:

Plug your TV into the HDMI port.

Step 2:

Right click on the audio icon on the task bar, and the click "Playback devices".

Step 3:

Choose your TV and click "Set default"

This sounds similar to my Vizio's second HDMI port; they sometimes become finicky after a while. You may have to just adjust and wiggle the end of the cable inserted into the TV; if it works, then make sure you don't even slightly touch it or else it'll lose signal again. If you have any other ports, try them instead; otherwise the problem may eventually get to an unusable point. You will have to have the port repaired or the TV replaced.

Most TVs will have HDMI and RCA component and composite jacks. Some TVs will also have a VGA port. Your laptop will have a VGA port. (If the laptop is fairly new, it may also have an HDMI port.)

Not all TVs will support an HDMI signal from a computer, so the VGA signal is often better. However, that limits you to SD (anything with HDCP will fail.)

Very few TVs ship with the HDMI or component cables. However, there are some vendors who do package the HDMI cable with their TV. Without knowing which exact model of TV and laptop, I can only make a few suggestions. I know that the TCP42ST30 (Plasma 42") doesn't have a VGA port.

Look at your laptop for any external monitor port. VGA ports are generally blue female ports with 15 holes (D-Sub). If your TV has a matching VGA port, get a standard VGA monitor cable.

If you have the VGA port on the laptop but not on the TV, you can try a converting from VGA to HDMI. (You may need a DVI to VGA adapter and either a DVI to HDMI cable or a DVI to HDMI adapter.) Note: this gives an analog signal (RGB format) to the TV. You'll also need to make sure that your VGA port is active (in the BIOS for some computers) and then set your computer to send the signal to the external monitor. It is best to turn off both the computer and the TV before connecting the two. Then turn on the TV and set it to the correct input before turning on the computer. (In Windows 7, I set the video signal for the external monitor by right clicking on the desktop and selecting Graphics Properties. Set the signal to the external monitor and click Apply. Then click OK (in the external monitor's screen).)

If this doesn't work, you need a VGA to component video converter. (Not a VGA to component video cable - those are for projectors that read the RGB signal.) See http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215-p1.html .

Some laptops come with an HDMI, mini-HDMI or a DisplayPort option. For the latter two, you will need the appropriate cable with that end and the HDMI connector on the other. Then connect the TV and the computer as described above. (Note: my TVs accept a computer signal at the HDMI port labeled HDMI/DVI. However, you need to make sure that your TV understands this signal. It isn't the same format as that from a set-top box. My laptop has VGA and HDMI out; the desktops have VGA, DVI and HDMI (on one).)

If you add a comment with the model of your TV and laptop, I'll be glad to give you more specific options to connect the TV and the computer.

I hope this helps.

(A DVI port is a digital video out option with ~21 pins and is usually white.)

The main tv Tuner signal board have problems and all those HDMI insert ports are shorted dead,those HDMI insert ports are put on by wave soldering machine and fused by iron core solders joints to the main tv Tuner board itself.These HDMI insert ports are not replaceable by hand soldering equipments or can buy those HDMI insert ports individually anyway.Tv still work wright?Yes? Why don't u just skips the used of those HDMI insert ports all together and tries used those RCA component cable connections like AV1 and AV2 on the tv.Or u must have some mechanicals skills and like take things aparts and putting back together again?Yes?Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv main Tuner signal board for the replacement to able to used those HDMI insert ports again.I have the same problems with my Samasung 46" all my HDMI insert ports are dead too,but the tv still functions.That what i did used RCA cable components connections for my cable box and blu Ray player.

Might some how got that HDMI input port shorted?Tries tv unplug and that HDMI cable input it into another HDMI port,replug tv back about an hour later.So the tv resetting itself back to factory setting.Tv on goto tv menu,goto tv PICTURE SETTING going down to do resetting.This should resetting the whole tv Tuner signal board.These steps,should help ur tv HDMI ports functions again.

It might be your XBOX Port, or your HDMI Port. Either one may be damaged.

I have a similar problem. The Sharp TV aquos appears to be shutting down my blue ray player and dvd recorder when connected via HDMI. They work fine and never close down when I connect them via the rca cables either single video connection or a composite 3 cable rca lead. I have 3 HDMI inputs on the tv and the problem occurs on all 3. Any suggestions?
