Thanks for using FixYa. Please check the X and Y sustain buffer boards. When either of these boards goes bad common problems include negative image, no image, vertical or horizontal stripes on picture, turns on and than turns off, and many more. You’ll need to open the back off the TV and check for any swollen/bulged capacitors on these boards and replace whichever has gone bad. If still the issue is not resolved, then please check the power supply board. All this is only recommended if you have electrical expertise and know how to solder/re-solder components as these units contain high voltages even when in off position. Please do accept the solution if the issue is resolved or post a comment for further assistance.

    I missed the audio issue. However, for audio issue please check the audio with a DVD
    player or cable box. Also try using component cables if using an RCA cable or vice versa. Check that all of the cables are plugged into the
    back of the TV & MUTE button is not pressed. Do a hard reset by
    unplugging the power cord for more than 4 hours and power it again, then go
    into the on-screen-menu and make sure the sap is off and stereo is on. If this
    all didn't resolves the issue then it is an Audio IC or bad speakers/speaker

    Please do accept the solution if the issue is
    resolved or post a comment for further assistance.

My Haier pv50v6-a8 won't turn on

From your description it is not clear unit shuts off or the blue power indicator stays on?
If you have blue light stays on there is nothing wrong wtih power supply.
You need to trouble shoot either on Y-sus or Main board.

Good luck

Haier 50 inch, has power, but no screen/sound

No. Either you have in a 'video' mode (inputs) or it's a defective unit. 
Bring it back to the store and let them bare the weight - sorry about your disappointing purchase. Better luck next time around.  :/
