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.

on the remote, is there a button that will let you change the option or set it to video? Try unplugging the cable as well and try different ports from the back till you get the video. you will have to video source cable and plug it to other available ones. try using a different cable as well if you have spare.
This is normal. Depending on what you have connected to it the lines could be white, black and white specs, or green. Just mode will show the entire picture event the parts that aren't supposed to be seen. I would not recommend that setting. Full is the best mode if you want to see the entire picture in the correct ratio.
If you haven't already bought a nice set of HDMI cables, go ahead and do so (just dont fall for the "gold plated" cables as they are a gimmick). Unfortunately, while we all want that HD quality, there seems to be some problems with the ln46a530 when switching from RCA to HDMI. On the bright side, they have been resolved in this forum post.
Best audio settings: Mode: Custom SRS TruSurround XT: On Auto Volume: On TV Speaker: On
(# of clicks): Balance: 0 100Hz: 8 clicks right 300Hz: 8 left 1kHz: 4 left 3kHz: 3 right 10kHz: 5 right
For best picture:
Most accurate settings (This with the mode at movie) Backlight = 6 Contrast = 85 Brightness = 49 Sharpness = 0 Color = 50 Tint = G50/R50
Black Adjust = Off Dynamic Contrast = Off Gamma = 0 Color Space = Custom Red: R33 - G0 - B0 Green: R18 - G52 - B0 Blue: R11 - G0 - B51 Yellow: R49 - G53 - B0 Cyan: R22 - G46 - B56 Magenta: R37 - G0 - B43 Flesh Tone = 0 Edge Enhancement = Off Xycc = Off
Color Tone = Warm 2 Digital N/R = Off HDMI Black Level = Low (actually it's disabled when playing Blu-ray)<-- set this according to your source! If you use a PC, or aPS3/Xbox360 with expanded RGB levels, you might need to set this tonormal! Film Mode = off (disabled) Blue Mode = Off
Unplug the TV and disconnect any HDMI cables to the set. If the issue goes away there is a possibility that your HDMI source is causing the problem. Anything on the HDMI can cause odd problems with the TV since the serial data and serail clock lines are routed on HDMI. Those are the 2 commmunication lines used throught the TV for operation so anything HDMI that might load down one of those can cause issues.
Normallly, if the picture size button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made.
A Motorola Cable box needs to be set up to go to a wide screen or zoom when an analog signal is detected.
Some Dish Network boxes have Size buttons on their remotes and also in their main menu.
It's difficult to determine the repair without knowing the types of the peripherals.
Hope this helps.
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.
