Yes, if it was fine before moving to downstairs, means it has lose connections or cold solder joints, especially on convergence ICs pins, please re-solder convergence ICs having mark like STK xxx

that manual is no longer available through mitsubishi or retreveo.com/ you may be able to purchase one through manualsinpdf.com

This set has a problem in the horizontal sweep circuit or in the main power supply. Most likely a failed component, and the set shut down to protect the rest of the circuit. If you know how to read a schematic diagram and how the circuits operate, then you will need a good multimeter and an ESR type capacitor checker to find out the short in this set. Sometimes the CRTs(Picture Tubes) will leak the coolent fluid out and onto the printed circuit boards. Also sometimes the convergence IC's can cause this problem, but if that is the case the small little pico fuses will pop also. If you have had no solid state or printed circuit repair experience, play it safe and call in a trained tech. Good Luck

that usually refers to either a diode or transistor in the xray protection circuit. There are only about 8 or 9 components that can cause that you will need the service manual to isolate which components make up that protection circuit. If you do have the service info and would like it I can post a link where you can get the mitsubishi service manual emailed to you cheaper than anywhere else on line.

your set is the V17 series so a code 22 means short protect. Which means the TV has a short circuit condition and is shutting down to prevent further damage.

1)Pull chassis or center PC board
2)Replace STK392-570 IC's
3)Locate green soldered-in pico fuses = use ohm meter
to find which ones are open ( bad ) = replace
4)Reassemble, test

What was the orginal problem?

Sounds like convergence issue--Replace Stk IC's and reset alignment.

The lamp is not enabled possibly due to the colour wheel motor not turning. Any broken glass jamming it? Or the lamp ballast has failed due to an old/worn lamp.

Most likely you need to replace the projection bulb. You can find them online. DLP sets are famous - or infamous - for burning out the bulbs/lamps.

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.

i think finding a downloadable service manual for your Mitsubishi HS-U580 VCR might take some searching, but here are a few options: Check the official Mitsubishi website's support section. They might offer downloadable manuals for older models.Many online appliance parts stores like RepairClinic or AppliancePartsPros stock service manuals for various brands and models. Search for your specific VCR model to see if they have it available.Websites like ManualsLib or iFixit sometimes host user-uploaded service manuals. While the availability and quality can vary, it's worth checking. If online options fail, consider purchasing a physical copy of the service manual from online marketplaces like eBay or Amazon. Remember, some websites might charge a fee for downloading manuals. Always be cautious of suspicious websites and download from reputable sources.

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.
