Lately the tv displays a b&w negative image instead of color. Unplugging and replugging the TiVo T800 (and waiting for the reboot) fixes the problem for awhile. Any ideas?

moved you out of computer to TV and best match SKY

Hi- My name is Shannon and I am with Suddenlink. The SL-TiVo remote can be programmed to control the TV and one other A/V device using these steps:

1) From TiVo Central, select Settings & Messages > Settings > Remote, CableCARD, & Devices > Remote Control.

2) Highlight Part 1: TV power, volume, and mute and press SELECT.

3) The DVR displays a list of television brands. Use the UP ARROW and DOWN ARROW buttons and the CHAN DOWN and CHAN UP buttons on the TiVo remote to highlight your TV brand and then press SELECT.

4) The TV Remote Codes screen appears. Follow the instructions on this screen to enter a code into your remote control. If the first code does not work, repeat the instructions to enter the second remote control code, and so forth, until you find a code that works. The remote is now programmed to operate the TV.

5) If also programming to control volume & mute on an A/V receiver for surround sound; Highlight Part 2: A/V volume and mute and press SELECT.

6) The DVR displays a list of audio/video receiver brands. Use the UP ARROW and DOWN ARROW buttons and the CHAN DOWN and CHAN UP buttons on the TiVo remote to highlight your receiver brand and then press SELECT.

7) The AV Remote Codes screen appears.

Follow the instructions on this screen to enter a code into your remote control. If the first code does not work, repeat the instructions to enter the second remote control code, and so forth, until you find a code that works. The remote is now programmed to operate the receiver.

The TiVo remote will now turn the TV on/off and switch inputs and adjust the volume and mute the audio on the receiver.

If you have any questions, feel free to email me at shannon-AT-suddenlink-DOT-com. Thanks!

Parts are not exactly easy to find for this brand---I would Google the model number with parts to see what is available and at what cost---look for the main board

I had the same problem....turned out it was the "lvds" cable that runs from the mainboard to the lcd controller board. Simply remove the tape that holds it to the back of the backlight housing and also remove the foil shielding tape from the connector on the lcd controller board.

I would use the warranty for this problem. The part that need to be replaced can be somewhat expensive.
With the credit card statement, you can use that as a receipt.

Hi
Goto Apple>SystemPreferences>

in the System section choose UniveralAccess>Seeing and make sure it says Black on White is selected, that Use Grayscale is unchecked and contrast is set to Normal.

If it's not that then its your display and needs a service.

All the best

Good Day, Props123;
It sounds like you may have locked-up the micro, try unplugging TV from wall for 3-4 minutes, then replug. If the TV was magnetized (crt) the osd would also display no color.
Good Luck, Big Irish.

please check you TV color system. you are not using the right color frequency. if your TV has got an auto color region select then set it to auto. otherwise, select the TV color mode until you get the right color frequency
