Tv will not respond to the side buttons and will not respond to the remote. changes inputs on its own, goes to hdmi on its own. the remote is not the problem. turns on & off by itself
Sounds like a main board fault. Contact any service technician to confirm. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

The problem is the "Y-SUS" board. It is inside the set on the left side with several aluminum heat sinks, under the left side brace bar. You can order this board from Union Electronics at www.ued.com .Search for part number: TNPA3243AB-PA
It lists for about 115$

You will be lucky if its actually the fuse. This HP TV is known for a circut board problem that was actually A KNOWN PROBLEM and HP still sold the TV's anyway. They were fixing the TV's for Free up until Dec when they decided to stop. You might want to contact the group that is taking legal action agaist HP for Selling a known defective product.
