How can I hook up prima ht8104 to my tv?or where can I find the manual?

I have never heard of this make in North America!

All about connections. You need a 75- ohm coaxial cable fly lead.

..

all I could locate for prima, give them a shot. 653, 673, 674, 842, 912.

You took the TV out of the mode for either satellite or cable and it need to be reset . check the user manual for the setting.
You didn't give model number for the unit/ I may be able to get you the instruction for you to reprogram the tv.

the panel is bad. if just purchased QUICKLY take it back. usually covered under manufactur warranty. next time stick with name brand tv. they dont make spare parts for the no name brand they just replace with new one. DONT GET RCA eighther. hope that helps.

try turning the channel up or down with the tv remote to input 1 or 2 depending on which one is being used for the dvd player. tv should use input 1. dvd should be on input 2.
when turning the channel set it to show the dvd screen, then go up 1. if it doesn't show, return and go down 1.

for advent remote codes manual (page is small print, advent is listed on far right)

Try pressing the TV button on the Prima remote to make it work on the TV. It should work on the Prima Tv without new codes. Codes would be needed for your cable box.
Consider calling Prima at 866-447-7462 for the codes. They should have a website for the codes or email you the codes for free.

PS Please rate me if this helps.
