Question LC-32A66M

[pradeep080112]

Hello, I am using SHARP Lc-32A66M tv since last 10 years. Now I am facing very unusual problem with this. I am not able to watch the pictures in 1080p or 720p format. It runs on 576p smoothly. I tried inputs from multiple source such as laptop, set-top box, fire tv stick etc. but nothing works.
Any idea???

Some better details are needed, what exactly do you mean not able to watch in 1080, do you mean when you set the resolution to 1080 in the device nothing shows up on the screen? Is everything connecting to HDMI with no adapters, converters, etc..?
