I am attempting to connect a Verizon Fios QIP6200-2 HD set top box to my Mitsubishi WT-46805 HD TV using the Y, Pr and Pb RCA connections (no HDMI port on TV) I cannot get any HD channels to work.


The set will have two component inputs, one is NOT HD.

You want to connect to the DTV input which if you look from the back will be marked 480/1080 I .

Also double check the connections to be sure blue-red-red and green to green.

Push power button and it clicks once then green light goes out and then clicks again and then nothing happens


Do the self check the model indicated has:

When power light goes out on the front of the set press and hold both the Menu and Input (device) buttons for at least five seconds and then release both buttons.

Watch the power light closely as it will blink a two digit error code: 2 blinks and a pause followed by 2 blinks is the most common one.

It will repeat the code about 5 times and then to get it to do it again you would have to unplug the set and attempt to turn it on again etc.

Let me know what code you find and I will tell you what it means and what kind of trouble you have.
