Right click on desk top and get the menu for changing screen resolution.

Try another monitor to be sure it is the monitor not the computer. If it is the monitor you need to take it to the repair shop. Be sure you are operating it in the proper range.

Check your cable connection on both ends. Try to change the cable.

You more than likely have bad capastors or diodes that will require taking the monitor apart then the parts replaced they will have to be soldered in and a small solder gun will be needed to keep heat as low as possible so the board doesn't get damaged. Use only japanese made gold rated parts

There are broken/exploded capacitors on the power plate, it is a 5 Minute job to replace them.

monitor led didn't light mean power cable is damaged or monitor you can try

Here is a link to the owners manual.

i think in your TV...... design ..... is such that once channels are autostored it cannot be retuned ..... so you try this ...... it may work ......... disconnect tv antenna cable ( or local tv channels cable ) from your TV & then click autostoring (auto tunning ) ..... definitely it will scans (search for channels ) ..... but since no cable is connected no channels will get stored ...... but previously autostored channels will get removed ...... so now again connect your antenna cable or local tv cable & then click autostore ...... it will scan for channels .... like this you can retune ....... but remember again you may get same quality of picture which you got earlier ..... if you want better quality of picture you have to use signal amplifier (increases cables signal's strength - then picture quality improves ) .....
