The reason your television keeps popping up the menu is simply because, either the remote or the televisions menu button is stuck.
To test if it is the remote, remove the battery from the back of the remote and try to operate the television from the buttons on the television to see if it works, if it pops up, then it means the problem is not from the remote and its from the television.
Either ways you have to open the remote and clean the panel with naphthalene, then adjust the menu button on it. or you can as well get a new remote for your television if you cannot clean it on your own.
Also to fix the television if it is detected as the fault, get the appropriate screwdriver, open up the television, then try to locate the menu button, then you adjust it and try to operate with either the remote of the menu key on the television.
Once it is seen to be working, ensure that the television is properly coupled back.
Always make sure the keys on the coputer and the television are not pressed too hard.
To calculate 7-2=5 (for example) on a business calculator: 7 + (all positive entries are followed by the + key) 2 - (all negative entries are followed by the - key) * (The Total key, marked with a star or a T finishes the calculation.)
It seems strange to people who use handheld calculators, but this is how adding machines have worked since the days of hand-cranked adding machines. The subtotal key (marked with S or a diamond) prints the running total without clearing it back to zero.
That message means the player cannot complete the HDCP copy protection check over HDMI. This usually happens with older TVs, receivers, or HDMI cables that do not fully support HDCP. Try connecting the player directly to the TV with a different HDMI cable, update the player firmware, or use the component YPbPr outputs as suggested if your display supports them.
ERR80 indicates a problem reading valid data from the EEPROM at power-on ("Protect area read error").
It is probably necessary to replace the EEPROM to fix this.
It is then necessary to re-set valid values for each address in the EEPROM by following the instructions in the link below:

You may need a repair center to do this for you if you are unable to do it yourself. A Sharp specialist should be familiar with this procedure.
You could try the re-set procedure first without replacing the EEPROM in case it's just a data loss.

This tends to be the result of an electrolytic capacitor somewhere, either on the main board or the power supply board bursting due to overheating. In this case you can pull off the back paneling and review the boards over to make sure all the capacitors are in excellent condition. After identifying a bad capacitor you can buy one from an electronics store in the area or a reputable online source. To replace it this will require soldering. Look for a capacitor with the same uF, the voltage can be the same or higher. Make sure all the power is out of the system before servicing, also make sure to note capacitor polarity observing the negative indicator line on the side. If your not sure this can be done at home I would recommend taking it in to a servicing shop. If you do not know what a capacitor looks like do a google image seatch for both examples of a good and bad copacitor. I honestly hope it's something much simpler, I hope this helped and good luck.
Just had this EXACT problem on a Sharp EL-9200C. I got the down arrow to go away and then the calculator functioned like normal. Here's how: I got a ball point pen and rapidly activated the reset button on the back, then rapidly pressing the CL key... probably about 45-50 times, but eventually it cleared all the memory out and the calc was able to boot up. This was after replacing the batteries multiple times and trying every key and every 2ndF key. I feel like the master of the universe now!
When experiencing slow or unstable internet, one of the first things to check is your Ethernet cable. Look for any visible damage, sharp bends, or kinks that might affect performance. Using a high-quality Cat5e or Cat6 cable can significantly improve connection speed and reliability. For more information on selecting the right Ethernet cables, you can visit NewYork Cables.

Don't refill toner cartridges on professional business machines. In most cases it is against the terms of the lease, as there is a clause for the company to supply toner, and they know when toner cartridges are changed. Also the quality is different and may damage the machine.
Question edited for clarity.Question moved from Misc to make model category.Unlikely you can get parts and it is a job for professional service anyway. The latch is part of the safety system, it has to operate a microswitch inside the machine and after installation, microwave emissions from around the door edge gap have to be tested.https://www.fixya.com/support/r29874712-repairing_microwave_ovens..
