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.
If your Mitsubishi WD-77731 TV screen has turned completely white with white vertical lines, it is possible that there may be a fault in the display panel or the video processing circuitry of the TV. This could be caused by a variety of issues, including a faulty LCD driver board, a loose or damaged video cable, or a problem with the TV's power supply.
Here are some troubleshooting steps you can try to determine the cause of the problem:
Check the video input: Ensure that the video input to the TV is working properly by connecting a different video source, such as a DVD player or game console, to the TV.
Check the video cables: Inspect the video cables that connect your video source to the TV for any damage or loose connections. If you find any damage, replace the cable.
Power cycle the TV: Turn off the TV and unplug it from the power outlet for 1-2 minutes. Then, plug the TV back in and turn it on to see if the issue persists.
Check for firmware updates: Check the Mitsubishi website to see if there are any available firmware updates for your TV. Updating the firmware may help to resolve any software-related issues.
If none of these steps resolve the issue, it is recommended that you contact a professional TV repair service to diagnose and fix the problem.
If you have replaced the DLP lamp and are still experiencing a black screen, along with a flashing red/orange light, there are a few possible causes. One possible issue is with the color wheel. The color wheel is responsible for producing the colors on the screen, and if it malfunctions, it can cause the TV to display a black screen. Another possible issue could be with the ballast, which powers the lamp. If the ballast is malfunctioning, it can cause the TV to fail to turn on. It is also possible that there could be an issue with the power supply or the main board.
In order to determine the cause of the issue, you may need to contact a professional technician who can diagnose and repair the TV. It is important to ensure that any repairs or replacements are done by a qualified technician to avoid any further damage to the TV.
It sounds like the wire you're describing is likely a connection wire for the audio component of your Mitsubishi 73838 projector. It's important to reconnect this wire properly in order to restore audio functionality to the projector.
Here are some steps you can take to reconnect the wire:
Identify the connector on the circuit board where the wire originally came from. This should be easy to spot as it will likely be the only empty connector in the area.
Carefully reconnect the wire to the connector, making sure that the wire is securely connected and properly aligned.
Check to make sure that the wire is not in contact with any other components on the circuit board, as this could cause a short circuit.
Power on the projector and test the audio to see if the wire has been reconnected properly.
Please be cautious when handling the projector. It's best to be sure that the projector is unplugged and you have a static free environment. Also, be sure to check the manual of the projector or consult the manufacturer to ensure that you are handling the projector in the correct way.

A blinking green light on a Mitsubishi WD-65833 television can indicate that the television is in standby mode, and is trying to establish a connection with a signal source (such as a cable or satellite box).
First, make sure that the TV and the signal source (cable or satellite box) are turned on and properly connected.
Check that the cables are securely plugged in to the TV and the signal source.
Make sure that the TV is set to the correct input (e.g. HDMI1, HDMI2) to receive the signal from the cable or satellite box.
Try unplugging the TV and cable/satellite box for a few minutes, then plugging them back in to reset the connection.
If the green light continues to blink, and you have tried the above steps, it is possible that the problem is with the TV's internal hardware or software. In this case, you may need to have the TV serviced or repaired by a professional.
It is also important to check the TV's manual or the manufacturer's website for troubleshooting information specific to your model.
Please note that the reason of the blinking light can vary depending on the TV model and the specific issue.
Mitsubishi rear projection DLP keeps turning off and shutting down. The red light then turns on for a while and then turns off. TV can be turned on again and works fine until a random shutdown occurs again. No fault codes are stored. No blink codes. No airflow warning messages. The original thermal sensor was replaced 8-1/2 years ago. Fans are completely clean and running smoothly. I fixed this problem by replacing the 8.5-year-old thermal sensor. The problem is gone. Mitsubishi thermal sensor part number 299P313010A. Manufacturer part number YS11A95B-C6. Do not use the connector plug. Strip the wires, and hard wire and solder the 2 connections. This might also apply to these models: WD-52631, WD-57731, WD-57732, WD-65732, WD-57831, WD-65831, WD-Y57, WD-Y65
Take the board out and use your heat gun to heat the board. Look for any loose connections and resolder if needed. I see why you when with inverter replacement. It sounds like a board issue.
Hello, one of the fans are bad or just clogged up, but only vacuum them off, NEVER blow them out, you'll wind up with dust bunnies in your optics causing blurry spots on your screen. Thanks Techman 57
all PC and TV and projectors all those have fans.
for sure thing that run faster, than say notepad
and yours does fan all fans suck in piles of lint
learn to clean it or have shop do it.
if ignored the fan jams up with lint, and stalls or makes noise (bad)
and stalls. all things with a fan does that.
and causes overheating damage that wrecks all elecronics with fans.
it needs service do get serviced
or rear the service manual
