Tv doesn't connect though coaxial hook up

Main board problem. Good luck,

Please contact the authrized service center for Hitachi. Sounds like corrupted firmware. Firmware update is necessary, and the firmware to Hitachi is very difficult to get by internet.

the video format from your medium doesn't support the tv's max resolution

Hey cthaemar, it sounds like it may have been switched off the correct channel. If it is hooked up with a Coaxial cable it will be on channel 3 or 4, and if it is hooked up with an AV cable then it would be on one of the inputs.

If it's channel 3 or 4 try pressing the gray TV button on the remote and changing the channel. If that doesn't work you may need to use the TV's remote or the TV itself.

If it's on an input press the same gray TV button and then try pressing Input. With this you can also try the TV remote or the TV itself to change those if our remote doesn't change it.

Let me know if you have any other questions or concerns!

If you have the DVR connected to the TV with the Coaxial and the HDMI that is probably causing the problem I work for a Cable company and have dealt with this problem on numerous occasions. Try just disconnecting the Coaxial cable from the cable box that should fix this issue.

change the tuner.

They don't make a coaxial to RGB or Component adapter. I know they make a coaxial to RCA. If you go that route you would just connect the coaxial to the video. Now if you do this not sure as to what would happen with sound, if you would have it or not. It is possible but not sure. The adapter I am talking about is called a
UHF Female to RCA Male Coaxial Adapter. Which can be found at most Radio Shacks. If this doesn't work I would contact the cable company about a cable box that they could then run the coaxial to and then the RGB or Component cables to the TV.

Hope this helps.

The way you have it hooked up right now will not work unless you have a coaxial out on your cable box going to the dvd recorder. Even then, picture quality will be severely degraded. The best way to do it is to leave your cable box hooked up to your TV via HDMI and connect your dvd recorder to your cable box via component video if your dvd recorder has a component video input. If it doesn't, then just use the composite video input. That way your picture quality will be better and you will still be able to record with the TV off.

connect coaxial cable connector from your cable service company to cable box-----in jack.
2-using coaxial cable connect cable box out to tv-vhf/uhf jack.
connect projection tv audio out (var-fix)jacks to avr 230 line in.

it could be any of the things you listed, the coaxial output on the dvr, where it says channels 3-4 out, the cable , or the coaxial input port on your tv. the dvd player is probably hooked up with rca cables (red white and yellow) so the reason you dont have the issue with it is because its on a different port, one solution would be to hook your receiver up to the tv using this kind of cable, this would also get you stereo sound, you would then watch dish network programming on a video input channel,
if you want to narrow the problem down, i would suggest hooking a vcr up with the cable thats connected to 3-4 out, play a tape and see if the issue continues, if not the issue is with the dvr, if so try a different coax cable, if this resolves the issue, the issue was the cable, if not unfortunately the issue is your tv
