Have TV Questions? Ask a TV Technician
Hi , I`m Jack , i will be helping you todayCan you please send me a reply when you are ready to proceed ?
What is this "magic box" , does it have a model number ?
Also ,Can you please give me the tv`s model number written on the back cover ?
How is that box connected to the tv ?
O.k and the tv actually turns off as if you had pressed the power button ?
That box , does it have a config menu ?
Let me have the model number of that box please , I believe I know what is happening and the tv is not the problem here
This tv is a few years old and has a maximum resolution of 720p or 1080i and while your cable box is auto adjusting to this , I don`t think that box is and is trying to drive 1080p resolution and cause the tv to shutdown
So unless you can tell that box to output a max res of 1080i , it won`t do
I take it that this box only has HDMI out ?
If it has only hdmi then perhaps this converter (or one like it ) could be used to take down the resolution into component type connection ;
Or this one
It still shuts down the tv ?
O.k then this is how I see it , we know this box is the culprit if the tv runs fine otherwise , no need to fool around with your tv and at this point what I see as the solution is to try and convert the digital signal that does not agree with your tv into analog .
Those units are not the state of the art when it comes to compatibility anyway , its either another different model or that 20 bucks converter.
Again , your tv is old but fine , it just cannot cope with this device

You mean the converter , if so then NO , just make sure it also has the audio and watch out , plenty of "component to HDMI " but you need the reverse HDMI>>>COMPONENT + AUDIO
Any questions on this ?Remember that you can come back here at any time after rating (no charge) if you have other questions related to that
