it could be a capacitor or more failing or the control chip failing. crt tv's don't have mean spare parts. as lcd's etc are more easy to get hold of cheap. you may be able to get hold of a copy chip you can get them for under 7 pounds. capacitors make sure you get the same rating that are on the old set. if they are blue change them to black type as blue only have a heat rating of 85c were as black have a rating off 105c. blue type are only recommended for audio but they put them in to save money. look for rounded tops on any capacitor and change them. also remove any and all the dust from the boards wires etc. as any dampness in the air will stick to the dust and cause problems.

EC means euro connector, I.E. Scart socket. For some reason there is no video signal coming out of the scart cable/out of the VCR or being displayed on the TV. Try plugging the scart plug into a different scart socket and see if that helps.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
