I had the same issue when replacing my lamp for the first time. I replace just the bulb with the Phillips replacement bulb. After installing the power down issue started and it would take up to 7 attempts before the TV would stay on with a picture.
Since I never had this problem until i replaced the bulb i decided to send the new bulb back and replace it with a difference one. In my opinion replacement parts are never made to the same standard as original OEM parts. This TV is definitely very temperamental in regard to the bulbs.
When the second replacement bulb arrived I decided to not only replace the bulb I also cleaned the connector plug in the cartridge with a QTip and alcohol. I did the same for the plug receptor in the TV.
When I replaced the bulb i insured the the top of bulb lettering was facing the handle of the cartridge so when you put the cartridge back in the TV the top of the bulb would be facing you.
I also cleaned the entire inside of the TV where the cartridge is inserted including the screws.
Once I did all this the TV turned on the first time and has been working fine for three days now.
I do believe the replacement bulb position is very important as to how it heats up and determines when it needs to cool.
I hope this helps others with the same success i had because I really do not want to replace this TV and start replacing all the parts others have done with little to no success for this issue.
Just took a look at the manual. This information is in the troubleshooting section of appendix H in the owners manual.
12. Lamp indicator light is a flashing yellow. Lamp cover door is open or lamp cartridge is not secure. See AppendixH for lamp replacement information.
Appendix H is a bunch of graphics. that you'll need to see to understand. i can't paste it all here.
dirt internal to the tv. suggest taking the screen off and removing the small rectangular panel in the middle and spraying off LCD panels located under metal fins. this should fix distortion.......for now.
i just got the same tv today and the same thing happend to me but it happend with the satellite input and i did not have the blue vertical lines i just had a black screen and sound. i unplugged the hdmi cable that carried the signal to the tv and plugged it back in and i had a picture. hope this helps
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.
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.
If your Mitsubishi TV LT-55154 has no picture but has sound and the green light is solid, there are a few potential causes for this issue:
Faulty backlight: The backlight in your TV is responsible for illuminating the screen. If the backlight is not functioning properly, it can result in a black screen while still producing sound. You can try shining a flashlight on the screen at different angles to check if you can see any faint images. If you can, it indicates a backlight issue. In such cases, the backlight unit may need to be replaced. Contact a professional technician or the manufacturer's support for further assistance.
Loose or damaged cables: Check that all the cables connecting your TV to external devices (such as cable/satellite boxes, DVD players, or gaming consoles) are securely plugged in. Ensure that there are no loose connections or damaged cables, as this can lead to a loss of video signal.
Incorrect input/source selection: Make sure that the TV is set to the correct input or source that corresponds to the device you want to watch. Use the TV remote to cycle through the available input options and see if the picture appears on any of them.
Display settings: It's possible that the display settings on your TV have been inadvertently adjusted or misconfigured. Check the TV's menu options for any settings related to picture or display, such as brightness, contrast, or picture mode. Resetting these settings to their default values might help resolve the issue.
Hardware malfunction: In some cases, a hardware malfunction within the TV, such as a faulty video processing unit or mainboard, can cause a loss of picture. In such situations, it's recommended to contact a professional technician or the manufacturer's support for further troubleshooting and potential repairs.
Remember to exercise caution when working with electronics, and if you are unsure about any steps or lack the technical expertise, it's best to seek professional assistance to avoid causing further damage to your TV.
