Lift error can occur if headphones are plugged in as well. You could also try unplugging and plugging it back in to reset it.

This is for whirlpool models.Try this procedure and see if it helps.what is your model?

Microwave will not operate (cook). F7 error code
appears on the display.

Electrical circuit interruption between L1 and Neutral in
the microwave inverter circuit.

Possible reasons:
1. Check door, hinge and cavity front alignment and adjust
as needed.
2. Check the operation of all interlock switches.
3. Check over temperature protector for the magnatron.
4. Check all Cavity Thermostats for closed circuit.
5. Unplug the oven for at least 40 seconds. If this solves
the problem
A. Check the Cooling Fan for proper operation or
blockage
B. Check the resistance of the magnetron thermostat.
It should be 0 Ohms, replace if necessary.
6. Check that the control cable to the 1100 watt inverter
is properly connected to plug P2 on the display PCB
& Adjust or Reconnect
7. If interlock switches operate correctly, replace 1100W
inverter.
8. If problem persists, replace control assembly.

You have a motor error. Remove any load from dryer and check if drum turns freely by hand. Check L1 power supply voltage, motorwindings, and motor thermal protector (if motor thermal protector has tripped,it may take up to 30 minutes to reset). If error persist, replace the motor with this new one.

To lift the protector off one edge of the display, place a sticky tape on the edge of the protector and then pull on the sticky tape to lift off the protector.
Lift the screen protector from one edge, peel it back to the last bubble then re-fix the protector in place by slowly apply pressure across the proctector as you push the protector onto the display making sure no bubbles forms between the display and the protector.

this one is so called a "self diagnostic system" that only sony servicemen can interpret internal failure exist in their unit checkout if the waranty period still active it might help u a lot from repair costs.

Hi there, I'm having the same problem with my TAVL1R, it's giving me error code 3/4 and the supposed 'Sony Techs' are not being helpful. I will appreciate any related recommendations that could help me resolve this issue. Thanks.

This should be a hardware problem. Take it to the Sony Center.

on my home theater display it shows protector push power
