My logik tv freezes. And can't change from tv to hdmi . No picture

change the HDMI cable

With the HDTV set for an HDMI Input that matches the HDMI Jack that you've connected to the cable HD STB (set-top-box or "converter"), use the cable STB remote to change channels on the STB - not the TV.

You can not change channels of the STB with your TV remote. You may however, be able to program your STB remote to operate your TV. Most will allow you to power the TV on / off; volume up / down / mute; change input (HDMI1 / HDMI2 / ANT / Composite / etc.) and even some of the more complex functions as well. Contact your cable company for more details.

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.

Based on what you're saying it can only be a few things.
Trying putting the HDMI cable into a different port on the tv and change input.
Try changing the HDMI cable.
If that doesn't work, change over to component cables, change TV input again and see if that works.

I recommend you switch from using HDMI cables to using component (R/G/B RCA-style) cables. HD picture is superior through component cabling, and solves several HD picture issues.

What is happening is that when video resolution changes (like from regular programming to commercials) the video information is poorly sent down the HDMI line. Component cabling from your DVR will eliminate this problem.

I hope that helps.

convergence board

Make sure you change the input that the cable is coming in on, If you was watching in HD mode then you was using an HDMI or compontet hook up.Look on tv remote for Video input button to select the componet input 1 or 2 or HDMI inputs which it is connected to. Look for a button on the remote called TV/VIDEO or INPUT

Sounds like a probable main board issue
