Your Mitsubishi VCR HS-U580 looks to have a problem with the information rollers and drum. Here are some things to check: Look for something blocking the VCR or cassette compartment that would possibly be stopping the guide rollers. Check the belt that drives the VCR mechanism. If it is loose or broken, you may also need to substitute it. Clean the video heads using a head-cleaning cassette to make certain they're not dirty. See if the drum motor is working. If it is not spinning, there may be an issue with the motor. If the trouble persists, it's an exact idea to get assistance from a professional technician or contact Mitsubishi's purchaser support for advice. Be cautious when dealing with electronic devices, and if you are not certain what to do, it's great to get assistance from an expert.

You can purchase a replacement power cord for your Mitsubishi model #LT-55164 from TVserviceParts.com. The part number for the power cord is 246C638010 and it costs $18.40.

Hoping you did not have electric overload that damaged the power supply, try unplugging the set and push the button On until no lights indicate anything. Then wait about an hour so the capacitors would empty themselves further. Next plug it back in and see if this worked. It is never wrong to push the edges a little in finding if the cables that go around the screen have a problem at that point. When one opens the TV (off power and unplugged) these flat cables should be checked for corrosion and right position in connectors. Corrosion is caused by little moist only, combined with the electricity. Then see if capacitors from the power supply, or any at all, have expanded tops. Those are the larger and smaller towers with metal on top that is divided in three parts. New ones alike can then be ordered but replacing requires basic skills. Further examples can be found on YouTube. Capacitors are common to fail early. Those larger ones have dangerous high voltage and can hold their charge for long span of time. it is not uncommon for devices like this to fail after being off.
