Please go to tuning menu and select Auto Scan/ Auto Tuning to tune all available channels to store in tv memory.
Factory reset actually delete all data/ settings in memory chip and set tv as it was in-box.
Thanks.

BE VERY CAREFUL!! This area is part of the output transformer which produces the HIGH voltage to the screen. The one to adjust is the SCREEN control. I would be surpised if just moving the TV would have caused this to have altered.

Try doing a "factory reset". This will "burp the baby". Turn the set on and ignore what you see. From the side control panel, push the volume+ and channel+ buttons in synch. This will take you to a base OSD (on-screen display) that can best be compared to the BIOS on your PC. The real goodies are here.

On the OSD, you'll see "picture", "audio", and "advance". Using standard navigational input on the remote, go to "advance". Tab down to "clear all". The set will appear to turn off, but the front LED will remain blue. The set is re-formatting the on-board memory and will restart in a few seconds.

Your panel should now restart as normal, but will be returned to factory "burn-in defaults". Your color and audio adjustments will be lost, so you'll have to do some fine-tuning in the regular OSD menu. Cycle power to the TV after you have made the desired adjustments.

TIP: Perform the factory re-set a second time, then select "picture". Toggle down to "video format". You might find it set to "Pal". Change this, using standard navigational input on the remote, to "NTCS" or "AUTO". Cycle power to the TV after you have made the desired adjustments. The TV will now perform at a refresh rate of 60hz, the American standard. "Pal" is 50hz, the EU and Asian standard. The improvement to image quality will be noticable very soon, as both your eyes and the set adapt to 9.94 hz improvement. NOTE: You may need to fine-tune the TV again after making this change.
