Inspite of cleaning with alcohol supco shows invalid display

Question edited for clarity.
Question moved from Cars and Trucks.

You just buy another one when they start to malfunction. I used to buy this type of thermometer 10 at a time. In catering they lasted 6 months. The advertising page doesn't say about Calibration, but ours had to be done and recorded once a month. We filled a glass with ice and added water. Let it sit for 10 minutes, stir and put the thermometer in and leave it until is settles. Press and hold the button at the end. Try removing your battery and wait 10 minutes before inserting it again.

Was the orange wire on a switched live on the old compressor connections? It may come on when the compressor goes off in that case. If not, recheck the schematic for the other end of the heater. If it has a neutral, join the orange to the live feed to the supco. If it has a live, leave the orange on the neutral of the supco.

If your phone show Invalid SIM it means the SIM card is corrupted you will have to change the SIM card.There is no other option.

try to clean contact for ink cartridge using cloth with alcohol and restart. let me know if work.

Did you make the disk if you made the disk your computer has to give it a digital signature so the DVD player can read it if you're using a regular DVD then I would very carefully using rubbing alcohol and Q tip clean the actual laser I would be very careful doing this if too much rubbing alcohol is on the Q tip it will ruin the laser you can also try resetting the DVD player by taking out the battery and unplugging it from any power source and leave it that way for at least 20 seconds to a minute if that doesn't work you might have something else wrong

The k5400 is not recognizing that the ink cartridge is installed. Clean the contacts on the back of the ink cartridge and also the contacts in the K5400 printer. I always use 91% isopropyl alcohol, Hp says to use distilled water. Do let the contacts completely dry before reinstalling.

When you go to the maintenance menu does the menu show the cartridge installed? If so here are some cleaning tips. First off do not use regular rubbing alcohol to clean anything electronic it contains 75% water this will damage some parts. Use "denatured alcohol" to clean the contacts on not only the cartridge but the printer. Be gentle with the cartridge and always go with the direction of the ribbon. If these do not work take the black cartridge to Walgreens and they can do an electronics test for you for free. Let me know how it comes out...Be mucho blessed...Mark
