The hdmi port of my vizio e231-b1 smart tv is not working. It displays either "No Signal" or "Not Support!" How can I fix this?


That message tends to result from a bad connection (perhaps the hdmi plug in the tv) or a source that does not comply with hdmi standards. This can often be the case when using a computer or gaming device for the signal source. Find a known good signal source and test, then if you still don't get a picture, switch the cable to hdmi 2 and try that one. Ports can go bad or wear out or get debris in them. Good luck.

I can not find an HDM1 port on my Sharp TV. Can I use the USB Port?


No, the HDMI plug will not fit into a USB port. (It's the wrong shape and the pins are different.) The micro-USB port can be connected to some USB ports for power, not data, with the appropriate cable (micro USB to type A). (Without the model of your Sharp TV, I do not know if the USB port has the right specifications. Some older TVs only have a "service port" which doesn't always provide enough power.)

There are HDMI to component video/audio converters that may work. They do not always work with copy protected (HDCP) content. See http://www.bhphotovideo.com/c/product/770115-REG/KanexPro_HDRGBRL_HDMI_to_Component_Converter.html for one example. (Composite video is not recommended since that will downgrade the signal to 480i. Component video supports 1080p signals.)

If you have 1 HDMI port, then a multi-port HDMI switch may work. Note: automatic switches often do not switch on their own with some sources. If the source never actually turns off, like some set-top boxes, you'll need to switch the unit manually.

I hope this helps.

Vizio tv says no signal on any of the hdmi ports


Unfortunately, you fried the HDMI controller. Not necessarily part of the power supply "main board." (Not sure which board is the HDMI controller in your specific TV. It's usually a separate board by itself). Easiest workaround is to use the "Component" cable connectors. The downside is you only get 720P. However, most cable/satellite and _all_ antenna signals are only 720P anyway. Most people only see 1080P when viewing Blu-Ray discs. Aside from replacing the HDMI controller, the cheapest workaround for multiple source connections is to buy an HDMI to Component Converter A/V box, which allows you to connect multiple devices to one box with one set of Component cables connecting to the TV. Then select various "sources" via the box.

46 inch Sony Bravia TV is 5 years old. HDMI ports 1,4 work fine but 2,3 don't.


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!

I need the maual for this rca tv L37wd22yx6 tv just keeps saying unusable signal and i need the maual


What is the signal source for the TV? Make sure that you are on the correct input. Use the Input button on the remote. If you do not have the original remote, you need one that matches that function. (Often a Source or Input button is not available on the low end remotes.) Check that you have the signal set to Antenna or Cable if you are using the coaxial connection and the source is TV. (Menu > Setup > Channel Setup > Signal Type)

If your source is a computer, use the VGA port not the HDMI port. Computers send a different type of video signal than video set top boxes. The L37WD22 can't interpret the PC signal on the HDMI input.

For a set top box on the HDMI port, the unusable signal message indicates a communication issue. Try pressing the Info button on the remote. If you see an additional message of Acquiring Channel, then the set top box isn't responding to the remote. Check that the device is on and set up correctly to communicate with the TV. (For example, if your set top box offers progressive scan, try turning of that feature with the control for the box.)

The L37WD22 was built by TTE for the RCA label. The manual is available on the TTE support page.

The direct link to the User's Manual in English is http://support.ttetech.com/RCATV/Assets/pdfs/L37WD22_16788070_IB_e-07.pdf .

I hope this helps.

Can i use the dv port on my monitor to display a movie on a led tv? i bought a dvi to hdmi adapter and plugged into my monitor dv port and the hdmi cable into my hdmi port on my tv and i'm getting nothing...


Ports on the monitor are for receiving the signals from the sources, not for sending signals out to another devices.
Your TV HDMI should be connected directly to the video source output, not through the monitor.
