Sharp LC-52SB55U powers on for 10 seconds then powers off

[shelby5041]

hi

i was given a sharp lcd tv with cracked screen

owner said tv worked fine prior to screen cracked

i powered tv on and it powers on ok backlight on...and there is a picture through the cracked screen area and sound..and the osd works fine....but after about 10 seconds tv powers off and opc light flashes as well as power light

all i would like to know is i want to verify the boards on the tv are good or bad

can the cracked screen be causing the tv to shut down?...normally if a lcd tv has a cracked screen from my brief experience is tv will stay on and not shut off unless there are other faulty boards....but maybe in this case its a safety shutdown???

any input?

thnaks

Would probably have to look up fault code.

understandable but can anyone tell me if a cracked screen would/could cause some tvs to power off after a few seconds?

or should the tv stay on as long as all boards are good?

thats all im asking
