D50u-d1 vizio tv blank screen - Vizio Televison & Video

If you have replaced all the boards in your Vizio D50u-D1 TV and you are still experiencing no sound and a blue screen, it's possible that the issue lies with a different component or a configuration setting. Here are a few troubleshooting steps you can try:
1. Check the audio settings: Go into the TV's menu and verify that the audio settings are correctly configured. Make sure the volume is not muted and that the audio output is set to the appropriate option (e.g., internal speakers or external audio system).
2. Check the input source: Ensure that the correct input source is selected on the TV. Sometimes, selecting the wrong input can result in a blue screen and no sound. Use the remote or buttons on the TV to cycle through the available inputs.
3. Test with different sources: Connect different devices (such as a DVD player or game console) to the TV using different cables. This will help determine if the issue is specific to one particular source or cable.
4. Perform a factory reset: Resetting the TV to its factory settings can sometimes resolve software-related issues. Refer to the user manual or Vizio's support website for instructions on how to perform a factory reset.
5. Update firmware: Check if there are any available firmware updates for your TV model on Vizio's official website. Updating the firmware can potentially fix bugs or compatibility issues that may be causing the problem.
6. Contact customer support: If you have exhausted all the troubleshooting steps and the issue persists, it's recommended to contact Vizio's customer support or seek assistance from a qualified technician. They may be able to provide further guidance or arrange for a repair if necessary.
Remember to exercise caution when working with electronic devices and consider seeking professional help if you are not comfortable performing the troubleshooting steps yourself.

If you have already replaced all the boards in your Vizio D50u-D1 TV and are still experiencing the same issue of no sound and a blue screen, it simply indicates a internal deeper underlying issue with the TV's internal components or firmware that requires a professional repair or assistance by any professional.

Check for a tripped circuit breaker in your fuse box or any gfi plugs in the same circuit need reset

that's because of the exposure to the ligth.. try moving it to another part of your house where the ligth does not reach the screen

Is the standby light flashing when you plug it in? Count the flashes. That tell you whats wrong with the TV.
In your browser type [Sony Visio D50u-D1 (no. of flashes) error code]. It should tell you how to fix it.

If you have the menu screen up does it look ok?

This sounds like a panel issue unfortunately, if its under warranty or you purchased an extended warranty great, if not your kind of SOL

You can replace the defective light bars in the panel, they can be ordered from ebay or shop jimmy, ebay is generally cheaper.

Question?

Start with the power supply board first. That usually fixes the problem. No need tor the T-con board.
