Hisense 55 in sceen has turned blue and no response to the remote

Hi try to use a power module if you can (it's a risky situation "high voltage" or get a qualified personel) on the power issue turn it to 5 volts up to 7 volts while checking the functionality.

Unplug the TV's power cord and hold the power button directly on the tv ,keep holding it for 20 secs or so then let the tv sit unplugged for a couple of minutes before you try it again.

Depends on model number but usually if LCD there is no adjustment.

I think you will need a remote as i looked up the manual and every setting can only be changed by remote :( Maybe get a universal remote??

If you wish to get more details; check the sites linked here. It has set-up code list & set-up procedure to many popular brand remote controls. Common set-up codes to check with TVs and other devices are given, in the order of the "device's brand name list" in alphabetical order. Pull up older posts.
