i have had optik TV for 2 months now. i have the Cisco Cis430 box

I have 2 TVs hooked up to this box. a panasonic plasma on HDMI and a Sony LCD on component. The plasma is used as TV at nite while the sony is a computer monitor. in the morning the sony is used as TV.

in the settings i have the aspect ratio set to 720p. after shutting off both TVs in the evening all is well. when i turn on the TV in the morning the settings are back to 480i SD. i have to go into the menu every morning to reset the aspect ratio and save the changes. when the installer set things up he set it as 720p and as far as i remember it was ok then. the "forgetting" of settings is a recent development.

any ideas of why this is happening? I do not shut the cisco off and had to reset it once (unplug) because of a HDCP error ..

I'd say the battery or some such device that powers volatile memory the setttings are stored in is non-functional or the non-volatile memory (drive?) is faulty. I've had to do cold reboots on Minerva (power out) and the settings don't forget.

Could try:

1) opening the box are looking to see if there's a battery to replace (I just had a peek from the outside and didn't see one)

2) Initiate a reformat of the box (I think the directions are in one of the links)

3) Call Telus

It sounds like your Panasonic plasma is negotiating the 480i resolution when it is powered off or on. Try checking your TV settings menu.

If you can't find a solution, you can test my theory by powering off the Panasonic, setting the Optik box to 720p and just use the Sony. Leave the Panasonic powered off in the morning and check the resolution. If it still goes back to 480i, please post the exact steps you are using to change the settings on the Optik box.

Please post back to let us know how things works out.

There have been previous complaints re this issue with some TV sets connected to the STB via HDMI. Some resolved by changing the HDMI cable. Others had to revert from HDMI to Component due to a 'handshake initialization' problem between the TV and the STB when using HDMI.

well to update.

This is what i have discovered thus far. I set the cis430 to 720p. both TVs say they recieve a 720p signal. When i turn off the panasonic on HDMI (50S1) it turns off the 720p setting. The sony (32xbr6) on component shows a 480i signal. i used to go back into settings and change it and save it as 720p on the sony. Left it alone one day and in the evening when i turned on the panasonic the 720p setting would come back.

so it is the panny or panny on HDMI that is causing this. guess i can live with it as the sony is only on as a TV for an hour or 2 each morning and at night its a computer monitor.

@Blintok, you can solve your problem by switching your Panasonic to component cables. You can test using your Sony cables if you don't have an extra set. Most people can't tell the difference, but some people say that HDMI results in a slightly better picture. Component cables are one direction, while HDMI has 2-way negotiation. Therefore your Panasonic won't be able to change the settings on your STB.

From your description, it sounds like Panasonic decided to set the other device to 480i when the TV is powered off. Then when the TV is powered back on it operates normally by negotiating the best resolution between th TV and the other device. Under normal circumstances where you only have 1 TV connected to the STB this wouldn't be a problem.

BTW can you post the model of Panasonic you have? (It might be an older model and they might have improved their HDMI handshaking since then.)

if i switch the Panasonic to component i then lose the use of the Sony for TV. And if i switch the Sony to HDMI wont that just reverse the problem?

I did post my Panny model above (50S1) TCP-50S1

thank you for the help but i guess i will just put up with it. As i said the Sony(32xbr6) is mainly a computer monitor and the main TV is the Panasonic.
If i have to i can turn it back to 720p or just leave it as its just to watch news b4 heading off to work.

Sorry I missed the model number and I got a little muddled. I looks like the model is fairly recent but I don't think it is standard behaviour for the TV to change the HDMI settings on "Power off". I suspect that if you switched the Sony to HDMI and the panny to component it would work properly.

Let us know if you try it.
