digital adapter will not synch

digital adapter will not synch

I have a digital adapter in guest room. The outlet is being used to power an amplifier installed at house input line. The technician left a “Power inserter” to use when I put a tv in this room. Has three connections: rf+amp, power and tv. How is this connected to the dta? I have rf+amp connected to the outlet, the power connected to to the dc adapter plugged into power and the tv connected to cable in on the dta.  It will not synch, therefore no picture.  Thanks in advance.

Re: digital adapter will not synch

Sunday morning update. Rather than utilize the power inserter in the guest room I provided a power source of 115 volts by snaking a small computer cord to the outside corner of the house near the amplifier. Plugged it in to outlet in bedroom. I installed a dual outlet in a housing and attached it to the wooden stake I previously used to mount the amplifier off the ground.  Plugged in the amplifier power adapter and connected it to the “power in” on the amp.  I moved the previous power source (the cable line into the guest room) from the amp and put it on the last available output of the amp to provide signal to the dta.  It then successfully synced up and the tv works now.  I am not too happy with the dta signal quality on a nice HD TV but...   That’s something to work on later. Only better signal would be another X1 box or a Comcast HD box. 

Thanks Andrew.  Problem solved.

Sounds right, is the DTA flashing or solid green?

It is flashing.  The adapter is known to be good as it will synch on the other tv I have that uses a dta. I am guessing with a hunch that I need another outlet since the current outlet is dedicated to providing power to the amplifier installed at the house input. Or perhaps a ‘zero loss’ splitter could be used at the outlet to connect one output to the dta and the other to the amplifier power adapter. The use of the “power inserter’ is proving unhelpful.

Can you look at your amp and see if it's getting power out of the power port or port 1 of the amp?

Hard for me to say. There is a cable connector on both the power in (15 v) and the rf power in.   The others are outputs and a connection for a voice modem.  I’m not sure which of those two power connections are coming from the guest room.

Because you have no incoming signal to the DTA (it's flashing), the DTA outlet is on the power port. If you have extra ports (1-4) on the amp, move the power over to Port 1. If you don't have an extra port, you'll probably have to have a tech out.

Re: digital adapter will not synch

Are you saying the dta outlet is on the 15 v power port or the rf power in? There is one vacant terminated port at the bottom of the amp.  Is “rf power in” port 1?  To be clear, if the dta (guest room) outlet is on the power port (not the rf power in connection), should I move the current “15 volt power in” to the ”rf power in” and the “rf  power in” to the vacant output port?

Move the cable on the Power In over to Port 1.
Yes to the vacant port as long as it's not the voip port.

Glad you got it all figured out. Your DTAs are Standard Definition, you can swap out to an HD version at your local service center anytime.(not sure if they'll still be free though)
