Hello

Power Supply board is dead.Replaced the power supply board will solved this.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

After the red 2 flashing starts, press the power button on the front of the TV and hold pressed down for ten seconds.
You will hear a faint click comming from the back of set.
After 10 sec release the button and wait 10 more seconds then press the start button and release right away.
The green light flashes and the bulb attempts to start.
I found my picture will turn on on the third attempt of the bulb restarting.

When you do this and the room is dark you can see the bulb attempt to restart, My bulb has restarted on the third restart every time.

(note: The three start attempt happen after I do the button pressing
1 time and I do not need further button pressing restarts.

I think panasonic needs to let us know what the problem is.

I called Panasonic and they told me to plug it into a wall plug by itself.

I have it plugged into a multi plug adaptor now and have not tried this yet.

Based on your message, your TV has a bad high voltage section. Probably the HOT (Horizontal Output Transistor) failed or shorted and it either killed the high voltage; that is why the picture went, but sound remained and you heard a pop sound fainting. Then, when you turned it off or unplugged it the protection circuit remained active.

There's a 75% probability it will require a high voltage and horizontal deflection amplifier overhaul. The normal cost of that should be less than $200 if you take it in.

For this problem, I would suggest to contact a repair tech and have him take care of the problem.

Good luck and have a great day!

hello you will need a replacement and they are not cheap sorry

This unit has a very complicated bulb replacement procedure. You would be much better off if you contact a panasonic service center and have them replace it. Bulb assy is pretty expensive as well. The part # is LFS4000PA1EB but you will have to go to panasonic to get it. Good luck. Thanks

1. Check the Input Source: Make sure you have selected the correct input source on your TV for the device you are using. Use the remote control to cycle through the input options until you find the one connected to your video source.
2. Check Video Connections: Ensure that all video cables (such as HDMI, component, or composite cables) are securely connected between your TV and the device you are trying to watch content from. A loose or faulty cable connection could result in a loss of video signal.
3. Restart the TV and Video Source: Try restarting both your TV and the device you are trying to watch content from. Power off both devices, wait a few moments, and then power them back on. This can sometimes resolve temporary glitches or issues with the video signal.
4. Check for Software Updates: Make sure your TV's firmware is up-to-date. Sometimes software updates can resolve compatibility issues or bugs that may be affecting video playback. Check the settings menu on your TV for an option to update the firmware, or visit the manufacturer's website for instructions on how to do so.
5. Reset Video Settings: If you've made any changes to your TV's video settings, such as resolution or picture mode, try resetting them to their default values. This can sometimes resolve issues with video playback.
6. Try a Different Device: If possible, try connecting a different device (such as a DVD player or gaming console) to your TV to see if the issue persists. This can help determine whether the problem lies with the TV itself or with the original device you were using.
7. Contact Panasonic Support: If none of the above steps resolve the issue, it's possible there may be a hardware problem with your TV. In this case, you may need to contact Panasonic customer support for further assistance or to schedule a repair.

1. Check the Power Cord: Ensure that the power cord is securely plugged into both the TV and the power outlet. Make sure there are no visible signs of damage to the power cord or the plug.
2. Inspect the Power Outlet: Try plugging another electronic device (such as a lamp or a phone charger) into the same outlet to verify if it is functioning properly. If other devices work fine, then the issue is likely not with the power outlet.
3. Check for Tripped Circuit Breakers: Check your circuit breaker or fuse box to see if a circuit breaker has been tripped or a fuse blown. If so, reset the circuit breaker or replace the fuse and try plugging in your TV again.
4. Test with Different Power Source: If possible, try plugging your TV into a different power source altogether, such as a different room or building. This will help determine if the issue is specific to the power source you were previously using.
5. Contact Panasonic Support: If none of the above steps resolve the issue and your TV still does not power on, it's likely that there is a hardware problem with the TV itself. In this case, you may need to contact Panasonic customer support for further assistance or to arrange for repairs. Be sure to provide them with details of the troubleshooting steps you've already taken.

Hope this helps
