Question about Sharp Televison & Video
Hard to diagnose some problems without hands-on. However, my guess is the power supply is fine, as are most on LCD's. The inverter board which powers the screen is the most likely cause of problems on that model set. Only other thing that i've seen is a shield that moved slightly beneath the main pcb. It moves because the putty that holds it in place was not rated at a high enough temp. and it simply turns to goo, allowing the heat sink to slide down and touch the main board. Three boards must be removed to find this problem. By holding down the power button on the set you may not be allowing the shutdown circuit to engage which means the problem could still be anywhere in the set. Sorry I can't be more help. All you can get is a guess here.

A component is shorting out, and the TV is auto turning itself off for protection. Usually it is a shorted out horizontal output transistor. Only a tech can fix this.

most likely the evenheat board is bad, but it could be the motor relay, get under the console and check the trouble shooting wiring diagram. there are several checks you can do to narrow it down.

Sounds like the switch is weight sensitive. A safety feature to prevent overheat as contents run low? The baseplate is probably not moving freely enough to move accordingly.

your garage door has saftey sensors at the door
these are photo eyes
in the owners manuel that came with the opener
that has pictures in it which would help
the photo eyes need to be clear of debri and aimed at each other with no obstruction
there are leds on each sensor and when aimes properly they should be light if i remember correctly
if you can not get them to light then you may have to replace the sensors
