You have main board issues, there is a 3.2 volt regulator on your TV that gives issues and will make the set turn on at random times, replace the main board and it should fix it, or you can order the part for under a buck from China and replace it yourself if you have soldering skills

Use your remote to reconfigure the picture. There may be a picture button on the remote that will switch the picture from 4:3, 16:9, Standard, Stretch, and so forth.

switch on the dvd player so it's playing, then do a new master tune. press the dtt/tv button so you are watching the internal freeview system, then press menu, then go to installation, and re-install all channels. the tv will then detect your dvd player in the intial set up/tune mode.

hope this helps..

According to what i could find, there is no way to actually SOLVE the problem, this is what i did find; The plasma display panel is lighting the phosphors by the discharge of internal radiation. Depending on the screen contents, in rare cases this may cause vertical stripes to appear because of failure to light. Please note that this is not a malfunction.

First make sure that the current Source or Input is set to TV. This is usually the only reason for the error message you see. To select the source, look for a Source or Input button on the original remote. If you have an universal remote with a button with the Source/Input label, you may need to try alternative codes to make the button work. (Power and channel controls will often match across multiple codes for the TV manufacturer.) Alternatively, check if there is a Source/Input button on the TV or a section of the menu system with the function. Once you set this source, try again.

Note: there was a period when manufacturers sold some TVs without tuners. They were labeled HD-ready sets. These can't do a channel scan and do not have an RF antenna jack on the set.

I hope this helps. Please add a comment with the model number of your Hitachi TV for more information on setting the source on your set.

Depends on the model number.

Under Audio or Audio Settings on the on-screen menu, TV Speakers is set to On. All of the cables physically connected to the TV and the input devices are secure. Switch to a different input device and verify there is sound from the TV speakers (for example, a DVD player or a gaming console).

It is reporting reduced air flow due to a clogged filter. Swing the case upwards, remove the filter and wash it is soapy water. Rinse, dry and replace it.

look on the back of the television and the DVD player, there should be a SCART socket and/or red, white and yellow AV sockets, either use a SCART lead and connect it to the SCART on the DVD player and the TV.Or use an AV lead with 3 auxiliary shape connectors and match the colour of each connector with the female sockets on both the TV and the DVD player instead of using the other component connections.
