How to connect hdmi cable from roku box - Mitsubishi WS-55613 55" Rear Projection HDTV

To connect a Roku box to an LC320EM2 TV, you'll need to follow these steps:

1. Connect the Roku box to the TV using an HDMI cable. Locate the HDMI port on the back of the TV and plug one end of the cable into the Roku box and the other end into the TV.
2. Power on the Roku box and the TV.
3. Change the input source on the TV to HDMI by pressing the "Input" or "Source" button on the TV remote. Keep pressing the button until you reach the HDMI input that the Roku box is connected to.
4. Follow the on-screen instructions on the TV to complete the Roku box setup process. This will involve connecting the Roku box to your home Wi-Fi network and creating a Roku account.
5. Once the setup is complete, you should be able to use the Roku remote to access various streaming services, such as Netflix, Hulu, and Amazon Prime Video, on your LC320EM2 TV.

If you have any issues during the setup process, refer to the Roku box manual or contact Roku customer support for further assistance.

what brand/model? Might want to try a factory reset

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.

is the normal tv input for high definition? Don't understand that term. I have a dish receiver, when I use an hdmi cable I get a really nice picture even with Roku

I think it will only work if connected directly to the tv with the correct cable.

If you have another HDMI port or A/V cable available on your TV, you don't have to unplug the cable box from the TV. You'll only need to connect the Roku to the vacant Input ports (HDMI or A/V) and change the input source of the TV accordingly.

This sounds like a basic setup, so correct me if I made any wrong assumptions.

You have 2 "output" devices: a Roku and a cable box. Both have HDMI outputs.

You have 1 "input" device (your TV) that has 2 HDMI inputs available.

So, you need one HDMI cable to connect your cable box to your TV. Remember what HDMI port it's connected to - the back of your TV probably says "HDMI 1" and "HDMI 2" or similar. That's the "input name" of your TV.

Connect your Roku to your TV with another HDMI cable.

Now turn on your TV and use the remote to change between the inputs. Most remotes have a button that says INPUT or SOURCE (or sometimes a dumb little icon with no writing). If you press that it should change inputs. Usually, each time you push the button will cycle to the next input, so sometimes you have to hit it a bunch of times until the on screen menu shows the input you want. Most TVs will automatically switch to the selected input after a few seconds, so you don't have to push any buttons on the remote to tell the TV to change inputs.

If "at the same time", you meant actually watching both Roku movies and your cable at the same time, you are talking about a TV feature usually called "picture in picture". That should be possible, but will depend very much on your TV. I'd suggest checking your TV manual, or calling the company's 1-800 number and asking them to talk you through it.

Hi,

You must match the TV's input connections and the Roku output on your remote. This means if the Roku's output is connected to your TV's "HDMI 2" (or A/V 2, etc.), you must be able to select HDMI 2 (or A/V 2, etc) on the TV - either with your remote or pressing a button on the TV itself.

Sometimes, the TV will skip over unused inputs when it was first set up. This is done to reduce the number of button presses to go from say "HDMI 1" to "HDMI 4" by programming OUT the HDMI 2 & HDMI 3 choices.

You'll need to program IN the input that your TV uses to connect the Roku if it isn't already available. You MUST connect cables properly if not using HDMI. RGB is Red-Green-Blue and must be connected to RGB jacks at the Roku and TV for a picture and the the White & Red (left and right) audio must connect the the corresponding Red / White audio jacks - or it will provide strange results.

Make sure the power plug is connected to an outlet that is ON and connected to the power jack on the Roku box itself. Unless you have a defective Roku box or TV, it SHOULD work. You can try using a different HDMI or A/V jacks on the TV to determine if it is the TV jacks or not.

Good luck!
