WHENEVER I POWER-ON THE MEGGER MIT520/2, AFTER INITIALISATION AND SELF CHECK I RECEIVED E77 ERROR ON DISPLAY. PLEASE HELP ME IN TROUBLESHOOTING MY MEGGER

Does the machine initialise? You should be able to hear it??? If not then it could be the formatter board but if it does initialise then check the screen or the cable

Nothing you can do, send back to Megger to get repaired.

Good Morning Friend,

I understand you are receiving error codes on your Frigidaire refrigerator, model# LGHC2342LF2. I suggest resetting your appliance, by either unplugging it or shutting the power off at your home's circuit breaker, for 3-5 minutes. Restore power. You will hear a beeping, and will need to press the "Alert Reset" button to stop your refrigerator from beeping. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your refrigerator status has changed successfully. If further troubleshooting is needed, I ask that you please let me know the error codes displayed on your appliance. Hope this is helpful.

-Best Regards-

Was it put into standy from the remote control and then just turned off at the wall? This can be a common cause, as it will be stuck in standby

turn power off the on to get printer to start initialising, as soon as it starts to move away from the home position turn off power again. Ther carriage can now be moved by hand. When you have checked your cartridge reconnect the power and allow the printer to reinitialise.

Please rate the help++++Thankis fore using FIXYA

Hey, I own one of these systems. Whenever I touch two of the wires together (shorting it out) the system shuts down and overload appears on the display. My suggestion is too check your wiring (especially in the spliced areas) or replace the wiring to the outside speakers and try it again. If you dont want to try that, take the wires you have hooked to the A speakers and see if they will work on the B setting (a quick troubleshooting technique). Please let me know if it worked for you. Good Luck!

The audio amplifier IC´s are on short circuit.

try unplugging the monitor cable from the computer and check if you get a power on self test displayed
if yes then the monitor is fine we have to troubleshoot the computer
and if nothing is displayed the monitor needs to be replaced.

need model number
