Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.

Sorry to hear you’re having trouble.

What specific inputs/ports are used here (hdmi, component, composite, etc)?
Have you tried any other device with the tv (dvd, etc)?

Customer: replied 1 year ago.
Hi,
HDMI No other devices other than the amp and its working
Expert:  Nathan replied 1 year ago.

Is the amp connected via hdmi?

Are you able to see the onscreen setup menu (on the tv) from the amplifier/receiver?

Expert:  Nathan replied 1 year ago.

Was the cable box connected through the amp?
Or was the box plugged directly into the tv?

Customer: replied 1 year ago.
ok this is not my area of expertise so the amp is connected by the cable box. does that make sense?
Expert:  Nathan replied 1 year ago.

There are 2 ways this could be set up

1) hdmi from cable box into amp, anther hdmi out of amp to tv

2) hdmi from box to tv + separate connections from box (or tv) to amp.

Customer: replied 1 year ago.
on the cable box it says digital audio. when unplugged no sound
Expert:  Nathan replied 1 year ago.

You are getting sound because the box must be plugged into the amp directly

if you aren't getting picture, then you either have a wrong setting on the amp, the amp video output is bad, the hdmi cable is bad, or the tv input ports are bad or set incorrectly.

Customer: replied 1 year ago.
i think there is only one hdmi cable that connects from the box to the tv
Expert:  Nathan replied 1 year ago.

Okay, that is different then.

I need you to actually look at all the connections, and see exactly what is plugged where (what label on each port, etc)

Customer: replied 1 year ago.
ok on the box or the amp
Customer: replied 1 year ago.
I have 4 cables running out of the box
Customer: replied 1 year ago.
coax,hdmi,digital audio,power
Expert:  Nathan replied 1 year ago.

Both.

I have to know all connections being used here, with as much detail as possible to be able to help fix it.

Not just names, you have to trace each cable between each device and tell me exactly which port is used on each.
Ex: hdmi out on cable box to hdmi1 on amp,

hdmi out on amp to hdmi3 on tv, etc

Customer: replied 1 year ago.
ok i understand
Expert:  Nathan replied 1 year ago.

thanks

Customer: replied 1 year ago.
digital audio goes into TV/CBL
Expert:  Nathan replied 1 year ago.

From the cable box, to the amp?

Customer: replied 1 year ago.
cable in feeds to wall cable port
yes on the amp
Expert:  Nathan replied 1 year ago.

Okay so that takes care of audio, which is fine

what is in place for hdmi from box to amp or box to tv?

Customer: replied 1 year ago.
hdmi into hdmi back of TV input 1 which I moved it to about 1"2 hour ago to try differnet inputs
Customer: replied 1 year ago.
different
Customer: replied 1 year ago.
that leaves only power
Expert:  Nathan replied 1 year ago.

Okay and when you go into the toshibas input menu, and set it to either hdmi1 or 2, you still get no signal on both?

When you tested this box with another tv, was that via hdmi also? Was it using this same hdmi cable, or a different one?

Customer: replied 1 year ago.
correct
2nd question they used both I think for sure their cable
Customer: replied 1 year ago.
would you like me to try my hdmi with that tv?
Customer: replied 1 year ago.
I can send him an email to confirm he used the HDMI?
Expert:  Nathan replied 1 year ago.

Yes, if you can. Want to make sure it's not a bad cord

if it's not the cord, and the box works elsewhere, that indicates a problem with the tv.

It would be helpful if you had anything else (dvd, game system, even another box) to test on the toshiba to be sure though.

Customer: replied 1 year ago.
I dont have anything else to try. Hang on he brought in a test TV as well and I think he tested that with the HDMI one sec I will see if he replies he works until 8
Expert:  Nathan replied 1 year ago.

Okay. Well if we know this box works via the same cord on another tv, then it is a tv issue in this case.

Customer: replied 1 year ago.
hmmmmm ok so I just plugged the cable,hdmI cable and power into the other tv and I have no signal
Customer: replied 1 year ago.
im doing something wrong
Customer: replied 1 year ago.
im bypassing the cable box with the cable going directlyn into the tv thats wrong
Customer: replied 1 year ago.
geez i need to use the HDMI thst is currently attached to the Toshiba right?
Expert:  Nathan replied 1 year ago.

You mean coax direct to the tv? That could work, but would be basic cable channels only, no dvr, etc

Do you have any other cords, that you can test, like the red/white/yellow out of the cable box instead?

Customer: replied 1 year ago.
nope so am trying to get the tv to the hdmi cable thats plugged into the toshiba
Expert:  Nathan replied 1 year ago.

you would have the box hdmi out connected to hdmi in on the tv (hdmi1,hdmi2, etc)

Customer: replied 1 year ago.
i cannot get the cable to reach.
How could he have tested the HDMI cable with the other TV when one for sure has to be connected to the box?
Customer: replied 1 year ago.
the cable in the Toshiba isnt long enough? this is a wall mount by the way with the cable going through the wall
Customer: replied 1 year ago.
I confused
Customer: replied 1 year ago.
I'm
Customer: replied 1 year ago.
steps required to try the box with another TV?
Customer: replied 1 year ago.
The 4 cables one of which is power are all there are. no yellow,red or white
Customer: replied 1 year ago.
Nathan? sorry did I lose you?
Customer: replied 1 year ago.
is the call over?
Expert:  Nathan replied 1 year ago.

No I'm here, sorry

Expert:  Nathan replied 1 year ago.

Please try to reply only once and let me respond, when you keep sending multiple lines you get lost in the queue and I don't get them

Expert:  Nathan replied 1 year ago.

If the cord goes through the wall, you clearly can't test it then, but you could test another cable if you have one or can get one. That would at least tell us if the hdmi ports on the tv are working.
