Problem switching between 480 and 1080i modes (get blue screen)
When using the HDMI cable mode, the set sometimes successfully switches between modes but often I get a blue screen. Once I get into a 480 mode, surfing the channels isn't a problem. In 1080i mode, when I surf the channels I'll encounter blue screens. If I use component cables, the set works fine.
Mitsubishi replaced the main board in the set but the problem continues.

Any contemporary monitor is able to switch analog/digital mode automatically if connection from signal source to monitor is set up properly.
Connect digital output from your graphic card to DVI input of the monitor. Disconnect any other signal cables from monitor and switch on both devices (PC & monitor). Wait a while. Monitor checks its inputs and a activates digital DVI, because it is only one active input on it.
If none picture excluding error message of monitor is displayed, go through these steps: 1) Check whether your monitor is set for automatic input selection. If monitor buttons have no response try to use analog input to activate screen (any picture, desktop background...) and then get monitor menu access by pressing menu button.
2) Find out what connector type has your graphics card in PC. Possibilities are: DVI, HDMI, DisplayPort and some their options. See Wikipedia for connector look if you are not sure. Remember that blue D-SUB (VGA) connectors are analogue and you cannot activate digital mode through analog VGA cable.
3) Use appropriate cable to connect monitor to PC. Example: Your PC has HDMI output. Use HDMi-to-DVI cable. Your monitor input is DVI and common DVI-DVI cable is not suitable in case you have PC with the HDMI. Note that DVI-to-DVI, DisplayPort-to-DVI etc. cables are available. You must buy right one.
Be aware that "Auto" button is inactive in digital mode of monitor.
Try connecting it using HDMI and the standard composite video. Then when you press the power button on the PS3, Press and hold it, it will beep once for turning on, then beep again, once you get the second beep, release the button. Switch your TV to the composite mode and go to your display settings. Then change your display settings to the HDMI cord and the screen will most likely go black. Then switch your TV to the HDMI mode and finish the settings change. Then, change the audio settings to audio as-well. Hopefully this helps.
If by regular cables you are talking about the standard red/yellow/white composite cables, then, yes, it will affect HD as composite cannot send an HD signal. Only HDMI and component (red/blue/green video only) cables.
Change to HDMI and let us know if it works for you.

Have you switched inputs? Some sets when you are on component/ HDMI/DVI will only allow a couple of PIX modes, Antenna will usually allow you to use all of your modes, If you have a cable box they sometimes will also have format modes. Try switching to cable channel 3 (if you get it or have a box on that) and changing format, try a VCR or something if no cable ch 3.
