without a remote and disabled keypad keys, the only other option, is to open the unit up a physically RESET the TV. remove the cables from the power board. i believe it has a phillips head screw. careful when you separate the rear cover from the front cover. there is a board screwed in the lower right corner, there is a connecter and a ground cable screwed to the rear cover. take your time prying on the rear cover. once you separated the two pieces, look for the light yellow board with your AC power source. Unplug it for 30 minutes and repeat the process. while your at it, also look down to the lower left side of the monitor. u should be able to see the keypad. press each button, while pressing, look to see if the button is pressing against the circuit board. it may be loose, try this test, u just may be able to fix your keyboard as well. hope this works out.

welcome to fixya!
without doing voltage checks, my best guess is this:
Plasma hpr5053 or hps5053 models will burn out a buffer board or both, there are two buffers and the Y board.
I usually change all 3 at once, but if on a budget you can try to remove one buffer and see if you get half picture (upper or lower)
this is something only a technician should attempt. the boards cost $200 each (buffers)
$300-$400 (Y board).
if you actually get half a picture the Y and one buffer are good, a bad buffer usually burns out the Y board. and in really bad cases the panel is bad also (not common, but possible)
For part#s , specific help you can post a model# , but again this is a repairmans job not something the average customer can fix.
hope this helps

Testimonial: "thank you sounds greek to me and costly but I guess I have to do what I have to do-----have you ever heard of a video IC board?"
At this point it appears that your main board is probably bad. You most likely have a 5 volt scource going to the main board but its not powering up the set. The main board is part number BN94-00796A.
You might want to have a technician look at the TV to verify this as the issue before purchasing it. Please take a few moments to rate my answer. Thank you.

•Stand within operating range of the
Insignia TV, then aim the remote at the TV's receiver and press the
"Lock" button on the remote control.
• Aim the remote at the TV and press the
channel buttons to make sure the TV is unlocked. When the TV is locked, it
shows a black screen and does not allow you to view anything else. If the
screen remains black, press the "Lock" button again. If this doesn't
work, change the batteries in the remote and start over at step .
