OLD VCR HOOK UP

I have an older vcr/dvr player that only has the three rca plugs for output.

I bought a RCA to HDMI adapter.  But when i plug in to the HDMI port on the ROKU tv it does see the connection...

What is required??

Re: OLD VCR HOOK UP

Are you sure you got the right kind of adapter?  Some go HDMI->RCA and some go RCA->HDMI.

You sure the Roku tv doesn't have a 3.5 mm jack labelled AV? For use with breakout cable like this:

Re: OLD VCR HOOK UP

My older VCR is also not working with the TCL Roku TV.  I have a cable with the 3 components at one end and the AV (to go in AV connection) at the other end.  I robbed it off an older Roku box I have.  But it is not working.  Sound is ok with a buzz added and picture is no good.  Any ideas of what I should do?  Its a new TV.  Cable was working fine yesterday (on different TV hooked to an old Roku Box).  Is there something wrong with the TV?

Those cables aren't necessarily interchangeable.  Didn't the TV come with a cable?  You can try mixing and matching the colored connectors and see if you ever get a picture.

Re: OLD VCR HOOK UP

The TV did not come with a cable. Mixing the output of the RCA end did not change anything.  Thank you for your advice that the cable I have may be mono directional. Since I had been successfully using it for an AV to RCA application but now it does not work for RCA to AV, likely the cable does not do what I am trying to force it to do.  Which is a better scenario than a brand new TV's AV input not working.  I can get a RCA to AV adaptor from Amazon for $7 or I can even get a RCA to HDMI cable for $11 and up.  However, I think I will just move this old VCR of mine to a digital TV I have that has the 3 RCA inputs.

Re: OLD VCR HOOK UP

Good plan!  You should note that those simple RCA-to-HDMI cables only work in a very specific situation - one that I've never seen.  You need a converter that's a little box and has a power supply.

You might want to try this AV adapter that claims to work with TCL TVs:

If you look at the pinout for that adapter it looks a little non-standard.  Ground is usually one of the end two conductors.  I don't know how handy you are or if you have an Ohmmeter, but you could check the adapter you have to see if it matches that one.
