YOU CAN HEAR SOUND. I HAVE PLACED IT ON WALL BRACKETS.
Check the backlight
SOURCE: dont know what size bolts
you should use minimum of 1/4" lag bolts by 2'" long.
Find a wall stud, and drive the bolts(one above the other into the wall through the mounting bracket holes.
SOURCE: hd tv makes a hjgh pitched sound whats wrong
Hi, the high pitched sound is coming from the coils or transformers on the power supply.
you can isolate the noise by removing the back and with the set on press gently with a plastic handle/item on each coil till you stop the noise. , you will probably have to replace the coil or the whole power supply, but sometimes you can tilt it over or secure it with silicone and it will stop rimging.
please click a thumbs up it this helps solve your problem

Metric M5 or M6, they should come with the mounting kit.
SOURCE: I was trying to wall mount a 32-inch flat screen.
If you get a slightly larger drill threader bit you may be able to rethread the hole to a slightly larger diameter.

If you see absolutely nothing on the screen then you may have a problem with the Lamp unit. If you can see around the back of the TV look to see if there is a vented opening with a noise of a fan and a rather bright light. If you see there is no light then try a reset (hold power button for at least 10 seconds). Turn the TV back on and the green LED should flash for a bit. If you still have no picture or video of any type (completely black screen) and have sound only you probably have a bad lamp. These lamps are around $125 or so and can be bought on Amazon or other sites that sell these parts. It's fairly simple to replace but make sure that the tv is unplugged and securely re-install the access door. Hope this helped.
