The machine was inadvertently switched to Prgressive Scan mode which only works if you have the proper cables and receiver. The following sequence runs through the menus that you cannot see when the mode is incompatible and switches off the progressive scan mode: Turn machine on (no disc). Press down arrow 3 times, then press OK. Press down arrow 2 time, then press OK. Press OK again. Press down arrow 1 time, then press OK.

On my e-motion tv when I switch it on and go onto did it says no signal....help please


Why does my TV say no signal? If your HDTV or Standard TV displays a "No Signal" error message, it may be due to one of the following issues:
  1. Determine how many TV's are affected.
    • If it is one TV, continue to step two.
    • If multiple or all TV's are affected, continue to step five.
  2. Ensure that your HDTV is on the same source/input as your MTS Ultimate TV service.
    1. Press the TV button on your MTS Ultimate TV remote control.
    2. Press the TV/Video button.
    3. Wait 10 seconds.
    4. Repeat steps b and c continually to cycle through all the available source/inputs on your TV until the correct source/input is selected. (ie. HDMI 1, HDMI 2, Component 1, Component 2, etc.) On standard TV's (non HDTV), you may have only 2 choices, TV or Video.
  3. If the source is correct from step two:
    1. Unplug the HDMI cable from your MTS Ultimate TV Set-top Box.
    2. Wait 30 seconds.
    3. Plug the HDMI cable back in.
    4. Wait for the signal to initialize.
    5. Make sure all cables connected on the set-top box and your TV are secure.
  4. If the problem persists:
    1. Unplug the power cable from the back of the MTS set-top box.
    2. Wait 60 seconds.
    3. Plug the MTS set-top box back in.
    4. Wait for the signal to initialize.
  5. If you are still experiencing a problem:
    1. Make sure ALL Ethernet and/or Coax cables are securely in place.
    2. Unplug the power from the MTS box labeled 2Wire or Pace as well as the affected set-top boxes.
    3. Wait 60 seconds.
    4. Plug the power back into the MTS box labeled 2Wire or Pace.
    5. Wait for the broadband light to turn a solid green colour.
    6. Plug the power back into the affected set-top boxes.
    7. Wait for the signal to initialize.
Good Luck

There are three ways you can connect a DVD player to a TV. Component video gives the best picture quality, but requires 3 cables for the video signal alone. S-video needs only 1 cable but it isn’t as good as component video. Composite video is the easiest connection to make, but gives the lowest picture quality.

Though all remotes are differnet just try this it can be kind of standard. But not all remotes are always compatible

1. On the remote control, press DVD once and Turn DVD player off

3. Aim the remote control at the TV and press SCAN. The red light will blink twice.
4. Continue aiming the remote control and click on and off at the DVD Player (which may take up to 5 minutes) until it turns off. Immediately press any key except VOL-, SCAN, or SET. If SCAN is pressed again after any key stops Auto Scan, the remote will continue Auto Scan of the next ID from where it stopped. If you have passed by the code that turns off the TV, press VOL- one or more times until the TV turns on again.

Poor picture and colour quality on hd through hd box red is pink fuzzy hd picture


You need to check the resolution of your TV thru your input setting, try to check which will give better picture quality between 1080 or 720 settings. Also secure that your input setting as either HDMI 1 or 2 or 3, you can use the original remote and change setting by pressing input in cycle.

Is it bad for a camera to continually change settings


Changing settings won't affect how well the camera works, i.e., the quality of the picture. The only thing that *might* happen is the mechanical pieces will eventually give out. Buttons, motor driving the lens and auto-focus, flash pop-up will eventually give out...but they are (usually) robust. Think about the button presses on a video game controller. Don't do something like toggle a switch back and forth dozens of times before each picture - this is unnecessary usage. Changing the setting for each picture - no problem.

I have a Coby dvd 505 home theater system and it's playing dvd's only in black and white Any suggestions?


There are a few possibilities. 1) You have the system on wrong broadcast system. Press the TV.Sys button on the remote. (In the US, you need the NTSC (analog) broadcast for older TVs). If you have lost the original remote, you need a replacement that matches the feature. See http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=12937326385240&smodel=DVD505&brand_pn=COBY_DVD505 for a substitute remote. 2) You have mismatched cables/inputs.

For the second issue, a composite video cable could be connected to a component video input. If both devices have component video, get a component video cable (red, blue and green for the video, separate red/white cable for audio); it isn't included with the player. Otherwise connect to the composite (AV) connections on the TV (yellow for video, red/white for audio).

If needed, you can reset the player as follows:
****RESET THE DVD PLAYER BACK TO THE DEFAULT SETTING***
1) Open the DVD tray.
2) Press the "Setup" button.
3) On the "Down" arrow, press it three times.
4) On the "Right' arrow, press it once.
5) On the "Down" arrow, press it three times
6) On the "Right" arrow, press it once, then press "Play/Sel" button.
7) Press the Setup button to exit.
*The default setting will take affect as soon as you press the setup button (step 6).

I hope this helps.

I have a (cyberhome ch-dvd 300) dvd player and changed setup menu now lost video cant see to change back is there a reset code or something


I wish I could find the website that gave all the repair hints for this DVD player, but I downloaded the info, and can no longer find the site. Here is what it says with regard to your symptoms. I hope this helps. I have done all the mods the site suggested, but continue to have difficulty with the remote, tray opening, etc. I have 2 machines and used to love them, but frustration has taken it's toll. Recovering from a condition with no TV picture
Accidentally switching to PAL and getting a rolling black & white picture happens all the time to baffle users, especially on models with a System or P/N key on the remote. To get back your color and sound just switch to the proper system in the menu or put in a movie of the correct type and it can switch automatically or try the procedure below for resetting to the defaults.
Sometimes owners will accidentally switch to Progressive Scan in the menu then get no picture at all. You can fix the no picture condition on the CH-300 by resetting the defaults to interlaced as mentioned in the users manual:

"To reset the VIDEO OUTPUT, turn Off the player, turn back On, open the disc tray and press and hold the Stop button on the player for 10 seconds to reset the scan mode."

The Reset procedure doesn't seem to work on all versions but you can sometimes get a usable B&W picture allowing you to get to the menu and change the settings by connecting the composite video input of your display to the Red Pr/Cr or Green Y component output jacks on the rear of the cabinet.
You can also go into the Menu and set it blind with the following key presses on the Remote:
1. With the unit Stopped, press Setup.
2. Press Enter.
3. Press the Down Arrow 3 times.
4. Press the Right Arrow Once.
5. Press Enter.
On 300Z & 300ZS models if the video is set to Progressive Scan and you can't get a viewable picture on the Red or Green jacks try going into the Menu blind and changing it back with the following key presses on the Remote:
1. With the unit stopped, press Setup on the remote.
2. Press the Right Arrow Once.
3. Press Enter.
4. Press the Down Arrow 2 times.
5. Press Enter.
6. Press the Up Arrow 2 Times.
7. Press Enter. This should switch it back to Interlaced scan with S-Video and Composite output.
To change the Parental Control setting on the CH-300 use the factory password of 3351. For the CH-400 use 1379.
