DVI to HDMI loses signal

I have an older silver MacBook Pro (17" purchased in 2006). I can provide more details such as video card, processor, etc once I get home from work.

I recently purchased an RCA TV 39" Class - LCD - 1080p - 60Hz - HDTV
Model: 39LB45RQ SKU: 5395953

I am connecting my MBP to the RCA via DVI to HDMI with the following:
BlueRigger High Speed HDMI to DVI Adapter Cable
Amazon.com: BlueRigger High Speed HDMI to DVI Adapter Cable (6.6 Feet/ 2 Meters): Electronics

When I connect the two devices I click on

detect device
select the 1080 60hz
select mirror.

The video is projected on the TV just fine, then it will cut out and bring a message that says something like: "Signal Lost."

Why is this happening?
I purchased this TV one week ago.
I purchased the cable two days ago.

Any advice would be greatly appreciated.

Thank you,

Geoffrey

is the cable at fault or connection is loose ? make sure you tighten the connection. if still has problem
then get another cable and try it.
